Aircraft Static Wicks

Aircraft Static Wicks

Aircraft Static Wicks - Static wicks are available with and without FAA and PMA approval and with various methods of construction. Dayton-Granger has PMA approval for a variety of discharge wicks for use on piston and jet aircraft. It also provides dischargers to OEMs.

Dayton-Granger's Javier Pacheco told us the company continues to advance its wick design, offering the Null Field discharger product, the Mircopoint discharger, the Carbonpoint discharger and a line of composite dischargers. The company also has a history of making high-quality aircraft antennas, plus lightning diversion strips.

What Happens When Lightning Strikes A Plane - Nz Herald

As Avidyne put it: “Static buildup is a very real issue that cannot be mitigated at the equipment level. If the aircraft OEM intended static wicks to be installed, it had a reason for it, and if it didn't, it's still probably a good idea."

Are New Avionics More Immune?

As we flew along, p-static began to build in the headphones. I had that happen a time or two before, and it always cleared itself within a few minutes. This time it didn't. It got so intense that I could not hear the controller or anyone on the frequency.

In addition, the needles for both VORs began to oscillate randomly. A quick check resulted in hearing only static, no identifiers, on both radios. Most of the aircraft skin is bonded (connected) to the static discharge wicks with the exception of the windshields.

When we fly through high altitude ice crystals (cirrus clouds), heavy rain, or snow, the static discharge wicks don't dissipate the precipitation static that builds up on the windshields. The precipitation static eventually discharges on its own, providing a fascinating web-like display a few inches in front of us.

Anytime an aircraft flies, the friction of the air over the aircraft's skin causes the aircraft to build up static electricity. Discharge of the electricity can generate radio frequency interference (RFI) or static noise level. RFI can become serious enough to interfere with comm and nav radios to the point that reception becomes impossible.

What Would Happen Without Static Wicks?

Any particulate matter in the air, be it rain, snow, dust, sand or even volcanic ash, will cause more RFI to be generated as the material sticks to the aircraft and any protrusions, especially antennas, which is why they have an anti-

static coating. On your next flight, while you sit back, relax and enjoy reading SkyMall, there is a good chance your flight crew is enjoying their own, shocking light show. Pilots see static discharges dancing on our windshields fairly often.

As a passenger, you might be surprised or even concerned at the display. It can be very impressive, but it's completely harmless. Take a closer look at one of the coolest light shows that pilots experience on the flight deck...

Yes and no. We asked Garmin engineers about the effects of RFI on its retrofit and OEM avionics, including its most modern integrated suites for jets. One said that some modern systems are impervious to the effect (including GPS receivers) because GPS operates at such a high frequency.

What Happens If A Static Wick Falls Off?

However, navs, comms and audio systems operate at lower frequencies and are much more susceptible to static interference if the aircraft has worn or missing static wicks. As one engineer put it, "The importance of static wicks is about the same for a 50-year-old airplane with old avionics as it is for a brand-new one with an ultra modern glass cockpit."

Friction generated as an aircraft moves through the air can cause a buildup of static electricity. The wick, which resembles a wire, transfers that electricity back into the atmosphere to prevent it from interfering with navigation and communication radios.

In the unlikely event your trainer should get struck by lightning in flight, the static wick would work to dissipate the energy from that strike. There are normally around 15-20 static wicks on all commercial aircraft.

This is a significantly higher number than required, ensuring that in the case of damage, there is always a sufficient number to perform their task correctly. If it looked similar to the windshield static discharge pictures, than it was likely static discharge off the wings.

Keep Your Eyes Open For St Elmo’s Fire

Since you mention you were near thunderstorms, it might have been actual St. Elmo's Fire. I'd love to see a photo if you took one! In addition to radio static, you may experience a corona discharge when flying in precipitation.

Corona discharge involves a static charge so great that excess electrons start to ionize air molecules and form a visible corona around sharp objects on the airplane—the end of the prop, antennas or wing tips, for example.

The effect is known as St. Elmo's fire. A corona discharge, taken to its extreme, occurs when a spacecraft enters the atmosphere and ionizes the surrounding air, turning it into plasma and wiping out communications until the spacecraft slows down.

Yesterday as we were beginning our descent into Atlanta on a stormy night we saw what was depicted on Star Trek Next Gen when they are going at low warp speed. It was amazing. This was out the passenger window first row of seats on a 737. Anyone know what that is called?

Why Does A Plane Need Spikes On The Wings?

We were flying through Wisconsin from Minneapolis to Fort Wayne International back in September on a stormy summer evening through a very energetic thunderstorm with lots of lightning. I saw blue discharges like your pictures in the cockpit but they were smaller and were dancing back and forth on the wing.

Can you tell me what I might have witnessed? You've seen or heard static discharges around your house. In the winter, when you take a blanket out of the dryer, you can hear the static electricity snap and crackle.

If you turn off the lights and give the blanket a shake, harmless sparks can be seen as the excess static discharges. This is the same stuff we see on our windshields. Without static wicks — sometimes referred to as static discharges — the aircraft would gradually attain an increasing static electric charge as it passes through the air.

Feature Identification - What Is This Tube-Like Thing Protruding From Under  An A330's Wing? - Aviation Stack Exchange

When flying through air with precipitation, such as ice or rain particles, this static charge can increase even more rapidly through a process known as triboelectric charging. Please note, Aircraft Spruce's personnel are not certified aircraft mechanics and can only provide general support and ideas, which should not be relied upon or implemented in lieu of consulting an A&P or other qualified technician.

Wick It Away

Aircraft Spruce assumes no responsibility or liability for any issue or problem which may arise from any repair, modification or other work done from this knowledge base. Any product eligibility information provided here is based on general application guides and we recommend always referring to your specific aircraft parts manual, the parts manufacturer or consulting with a qualified mechanic.

Toll Free: 877-477-7823 Customer Service: 800-861-3192 Fax: 800-329-3020 As an aircraft flies through the sky, air and precipitation rub against the aircraft's skin causing a buildup of static electricity. The same thing happens when you rub a balloon on your hair.

When this electrical charge is strong enough, it can cause static on aircraft radios, interfering with communications. In typical conditions, the charge is continuously dissipated by small, pointed static discharge wicks mounted to the trailing edges of the wings and tail.

No matter the manufacturer, prices can range from $40 to as high as $85 or more for a wick suitable for a single or twin, and far more for jets. In general, most wicks for singles and light twins measure roughly 7 inches long and weigh .50 ounces each.

P-Stat Lesson Worse In Snow

Still, all of this effort has little effect on in-band noise sources, particularly in VHF. As Avidyne explained, as static charges build, move and collapse on the airframe, very wide-band RF energy is released; some amount of this energy will fall in-band for the VHF and other RF receivers.

The in-band component of the static noise is picked up by the antenna and amplified in the receiver as if it were the intended signal. Look at a static wick and you'll see a cord-like structure riveted directly to the skin of the trailing edge to make metal contact.

Aib Nigeria On Twitter:

It may be wider where it connects to the airplane than at the end. Static wicks are bonded to the metal structure of the airframe. Because they are constantly transmitting electrons into the atmosphere, they eventually wear out—or at least the tips do.

Once that happens, RFI can develop on the airplane. If a static wick falls off, it's not a huge deal. As they are deliberately slender, and attached to the extremities of the aircraft, it's actually fairly common for them to become loose and fall off during flight.

Progress At Cirrus

Unfortunately, as a passenger, you probably won't see static discharges. I've never seen or heard of them happening on side windows. If you are flying on a stormy night, however, you might catch a glimpse of St.

Elmo's Fire on a wingtip similar to the photo above. If you see it, be sure to take a photo. It's a rare phenomenon and I'd love to see another picture of it! This charge cannot build up forever, and once the charge is large enough — based on a range of factors — it will look to discharge itself back to the surrounding atmosphere.

The charge will look for the easiest route. This is usually the thinnest part of the aircraft, such as the wingtips and tailplane. The resulting discharge of energy can result in a loud bang, heating, and even visible sparks.

They are unobtrusive for the most part, and sometimes they are overlooked on a preflight inspection. But static wicks—the small wires protruding from the trailing edge of an airplane's wing or empennage—serve an important function in the air.

Rarely, this can mean that the aircraft might even begin a flight without all the static wicks. Commercial aircraft can fly with some static dischargers missing for a set number of flights before they are required to be replaced.

Partnership Os - Lh - Austrian Airlines

Although I'm an avid fan of Star Trek – Next Generation, I don't know what you are describing. If you can provide a picture of the actual occurrence or a picture of what "Low warp speed" looks like, I might be able to figure out what you were seeing.

On the plane, St. Elmo's Fire appears as a bluish glow or flame emanating from an aircraft wingtip or nose. The phenomenon is rare on aircraft; most pilots have probably not seen true St. Elmo's Fire.

St. Elmo's can appear in heavily charged air in the vicinity of a thunderstorm and is harmless to aircraft. Turning on the landing light revealed that we were flying in moderate to heavy snow. I knew snow was worse than rain for generating p-static, but I'd never encountered anything like this.

I knew it was snowing in Grand Rapids and forecast to continue, so I started considering turning back to Cadillac where it should just be decent VFR with a high overcast. At that point I recalled something I'd learned when encountering St.

Elmo's fire and a remark made by an old freight dog. If you ride long enough through snow, fog and desert dust, you'll likely hear the audio signatures of static built up on the airframe. It can be severe enough to shut down a comm and nav receiver.

The troubleshooting chase can be as frustrating for the techs as it is for pilots because everything will likely work perfectly on the ground. Static discharge wicks should be the first accessories to consider, especially when committing to a new avionics installation.

But antennas could be the culprit, too. They are designed to be more attractive to static energy, than any of the other aircraft extremities such as antenna, wingtips, or flight controls. As the plane moves through the air, the wicks help to discharge any static electricity that has built up from the friction of the plane moving through the air.

Owners may struggle with getting the correct replacement, especially when sourcing them through mail-order supply houses. Aero-Mach's Jon Snider told us choosing the correct replacement wick should be easy because it's usually governed by the original type certificate of the aircraft, and replacement options are prescribed by the aircraft repair manuals.

St. Elmo's fire is a form of plasma that can occasionally be seen emanating from roof peaks, towers, spires, and other pointed objects in the vicinity of thunderstorms. The phenomenon is often seen prior to a lightning strike.

If you see it, get indoors! So, there you have it — the mystery of the static wicks solved! Now you know just what those metal rods are and why they're on plane wings. Next time you fly, take a look out the window and see if you can spot them attached to the back (trailing edge) of the wing!

Aircraft Satcom Systems - The cost of using this equipment is high and the purchase price can be upwards of $50,000 US and in most cases upwards of $100,000 US including antennas. A high price but you have access to broadband data from pretty much anywhere – the only limitations being at the Poles.

This equipment requires a significant installation investment and is installed under a STC. Passenger Information and Entertainment Services Domain (PIESD) encompasses all passenger services, mostly known as IFE (In-Flight Entertainment) and includes video streaming, passenger internet and intranet browsing, access to social media... This domain is today handled by cabin SATCOM

(average throughput 20/30 Mbps) but cockpit SATCOM with cabin capability can fulfill it (throughput <1 Mbps) for basic needs and/or as a backup for cabin SATCOM means. In addition, EUROCONTROL is a key player in the coordination with the ESA Iris program, which aims at validating a satellite-based air traffic services datalink using SATCOM Class B and paving the way for evolution to Class A. Iris takes advantage of IP-based

broadband to provide secure and high-bandwidth cockpit communications for exchanging flight information and trajectory data with the ground for oceanic as well as continental communications. The crew can also use the SATCOM to contact the AOC regarding, for example, an HF system fault message alert during the flight which could affect the next flight dispatch.

This enables maintenance teams to be ready to check the fault on arrival and minimize delay. Communicating while aloft should be as straightforward as it is on the ground. Our offerings make on-board communications simple and easy to manage, with solutions built for any size aircraft performing any mission, with any service provider.

At the time of writing this equipment uses geostationary satellite networks and large high-gain antennas, however in the future this capability will also be provided by Iridium Communications at a lower price-point. It may even use its own terrestrial based network – such as services offered by Gogo, SmartSky and AirSky.

Other manufacturers of operational equipment for this market include Rockwell Collins and Honeywell. The LCS offers a light and efficient SATCOM solution. Beyond standard SATCOM voice and datalink usage, the LCS will unlock the use of new connected applications such as Mission+ from NAVBLUE (an Airbus subsidiary).

Airlines will have new means to optimize their operations. Typical users of this equipment are private owners, tourism/charter operators, and some first-responders. They typically fly small fixed wing and single engine aircraft and helicopters. Well-known providers of this equipment are SpiderTracks, Blue Sky Networks, Guardian Mobility, and TracPlus Global.

Installation is cheap and there are no installation certification requirements for this type of equipment. Today, satellite constellation technology enables more throughput, taking into account regulatory requirements and the growing number of customers. However, while airlines need and expect more connected IP-based applications, it is fundamental to ensure aircraft systems remain protected.

All cockpit communications to/from aircraft are routed through Satellite Service Providers (SSP) infrastructures (Satellite, Gateway/GES). Today two SSP are recognized to be used by commercial aviation to exchange aircraft cockpit data with ground users: Inmarsat and Iridium.

Since the early stages of commercial aviation, and in order to enhance safety, regulations have required long-range communication means for flying over oceanic and remote areas. Initially performed exclusively with HF voice communication, the cockpit SATCOM which operates in the L-band radio frequency is now recognized as an alternative means of communication with the ATC (Air Traffic Control) or AOC (Airline Operation Center).

For continental areas such as Europe, VHF is mainly used thanks to a widely deployed, but increasingly congested, VHF ground network. Flight crew can operate and control LCS with the new radio control means RMP (Radio Management Panel, cf FAST article Cockpit communication - new-generation audio system) or with the legacy MCDU (Multipurpose Control and Display Unit) and ACP (Audio Control Panel)

, according to aircraft configuration. In the FCI context, SATCOM, together with the terrestrial communication systems, will enable the future SATCOM concepts supporting IPS communications and Performance Class A, which are being developed in the context of the SESAR, NextGen and CARATS ATM modernization programs.

The focus in SESAR is primarily on safety of life communications and also in Airline Operational Control (AOC) SATCOM communications, as both are allowed to operate in the same frequency bands under the AMS(R)S ITU frequency allocation.

Pricing is around the $1,500 - $3,000 US mark with additional operational costs for the tracking service in the vicinity of $50 - $150 US/month. Some manufacturers also have a built-in cellular network option that complements the satellite technology.

The cellular option is a cost-saving measure and used when in-range of cellular networks. During the development phase of the LCS, flight tests were conducted on several Airbus aircraft types. More than 70 hours of dedicated flight were performed.

The objective was mainly to check the correct behavior of the SATCOM interconnected to the avionics, ensure there was no interference with other Communication/Navigation/Surveillance systems, evaluate the end-to-end connectivity performance through satellite space and also the ground segment during all

phases of flight and all flight envelope of the aircraft. Flight crew workload and Human Machine interface were also evaluated. This equipment is typically used by first responder aircraft and the military and manufacturers include, Blue Sky Networks, Flightcell, Honeywell and Latitude/SkyTrac.

A typical installation will take 2-3 days and will be installed under a Supplementary Type Certificate (STC) or an engineering modification. At EUROCONTROL, we support the technical, operational and standardization activities in SESAR2020 Wave 2 PJ.14 Solution 107 "Future Satellite Communications Datalink".

In particular, EUROCONTROL is an active contributor to ICAO Working Groups in the update of the SATCOM standards (SARPs and Manual) to include provisions for the future SATCOM systems, meeting SATCOM Performance Class B and in the future SATCOM Performance Class A systems supporting ATS Baseline

2 (B2) and B3 service requirements. EUROCONTROL is also a participant in EUROCAE WG-82 activities aiming to develop ATN/IPS and Voice over IP capability for future SATCOM. Exchanges with ATC are essential to prevent collisions, ensure and optimize the traffic in controlled airspace.

Aircraft automatically report their position (ADS-C) and also exchange data via pre-formatted messages (CPDLC) to allow controllers to safely guide aircraft to their destination (routine operations). Both functions are part of FANS application (FANS 1/A in oceanic and remote areas).

Flight crew can contact or be contacted by ground control by voice means (SATVOICE function) in distress, emergency or flight safety situations (non-routine operation). Such communication exchanges supporting safe operation of aircraft are part of the "Aircraft Control Domain" (ACD).

These critical communications must demonstrate minimum end-to-end performance known as PBCS (Performance-Based Communication and Surveillance). PBCS defines a minimum performance to allow an aircraft to use optimized routes (therefore allowing fuel savings). Passengers and flight crews can enjoy the luxuries of high-speed data connectivity powered by our global satellite communications.

From the sky to the ground, our communication platforms are deployed worldwide in all types of aircraft so people can stay in touch. In some cases, cellular technology supplements the satellite technology, providing operational cost benefits and broadband data for email and internet access.

Pricing is around the $10,000 - $20,000 US mark including antennas. The upper end of this price bracket includes add-on's that include WiFi and Bluetooth™ connectivity for smart devices, or Iridium Push-To-Talk (PTT). There are additional operating costs for tracking and voice services, and they are at a similar price point to the basic tracking devices above.

There may be additional costs for satellite voice calls, but cellular calling costs are negligible. Satellite communications (SATCOM) are already today an important component of aeronautical communications, in particular for the oceanic airspace. In the future, SATCOM is expected to be equally important also for the continental airspace and become an integral part in the Future Communications Infrastructure (FCI).

In addition, evolving satellite constellations provide new SATCOM systems offering new capabilities to meet the current and future aviation communication needs. High Capacity Multi-Systems This grade provides high-end satellite equipment for high-capacity voice and high-capacity data.

There are many voice and data channels and they are accessible to multiple onboard devices. This system is typically installed in the avionics bay of a wide-body passenger jet or a business jet. Some dual-engine operational helicopters use this equipment, however that is the exception and not the norm.

Jim FAWCETT, Lead Flight Test Engineer and specialist in communications systems describes the experience: "We operated our flight test aircraft throughout the entire flight domain to ensure good SATCOM coverage even in case of manoeuvring. To ensure good geographical coverage and correct voice and data service behavior at satellite handover boundaries, we even operated our A350 on a 12-hour flight from Toulouse in France to Gander in Canada and back, without landing!

Our crew found the HMI (Human Machine Interface) intuitive and easy to use. The system behaved well and should provide a secure solution for our customers in the years ahead. Typically, thanks to the EFB (Electronic Flight Bag) live weather forecast application, the crew on a transatlantic flight can detect an unexpected approaching storm cell with potential turbulence as a complement to the onboard weather radar.

They can then call the ATC using the satellite communication system to get clearance to change the flight plan. The next Inmarsat LCS evolution under development is FANS C over SATCOM (FAST article FANS C - on page 34).

This future capability will enable the use of SATCOM for ATC datalink communications over ATN (Aeronautical Telecommunication Network). It will provide an alternative means to alleviate the European VHF datalink network, expected to be saturated in the near future, especially in high density areas, mitigating the risks of quality degradation of datalink services for ATC and AOC.

FANS C over SATCOM will enter service on A320 and A330 aircraft families and will be capable of 4D Trajectory Based Operations (new mandate from 2028). Exchanges with AOC allow airlines to support aircraft operational efficiency.

It is part of Airline Information Services Domain (AISD). Aircraft can receive and send preformatted automatic maintenance reports via the ACARS network. To support flight operations, crews can request weather data updates during flight to optimize flight path while ensuring passenger comfort (cf FAST article EFB - the new standard).

Aircraft also send maintenance reports to the ground automatically, in order to anticipate dispatch and maintenance activities after landing. Voice calls also offer the possibility for pilots to exchange operational information complementary to ACARS with their airline control centers.

Basic Tracking Devices This is typically a single device that is affixed to the glare shield with suction cups. Its main purpose is to track the position of the aircraft and send event information. This type of equipment almost certainly has a messaging capability, but no voice capability.

The tracking and messaging data is sent to and from the aircraft using the Iridium satellite network.

Aircraft Satcom Systems

Aircraft Satcom Systems

Aircraft Satcom Systems - The cost of using this equipment is high and the purchase price can be upwards of $50,000 US and in most cases upwards of $100,000 US including antennas. A high price but you have access to broadband data from pretty much anywhere – the only limitations being at the Poles.

This equipment requires a significant installation investment and is installed under a STC. Passenger Information and Entertainment Services Domain (PIESD) encompasses all passenger services, mostly known as IFE (In-Flight Entertainment) and includes video streaming, passenger internet and intranet browsing, access to social media... This domain is today handled by cabin SATCOM

(average throughput 20/30 Mbps) but cockpit SATCOM with cabin capability can fulfill it (throughput <1 Mbps) for basic needs and/or as a backup for cabin SATCOM means. In addition, EUROCONTROL is a key player in the coordination with the ESA Iris program, which aims at validating a satellite-based air traffic services datalink using SATCOM Class B and paving the way for evolution to Class A. Iris takes advantage of IP-based

How To Operate Lcs

broadband to provide secure and high-bandwidth cockpit communications for exchanging flight information and trajectory data with the ground for oceanic as well as continental communications. The crew can also use the SATCOM to contact the AOC regarding, for example, an HF system fault message alert during the flight which could affect the next flight dispatch.

This enables maintenance teams to be ready to check the fault on arrival and minimize delay. Communicating while aloft should be as straightforward as it is on the ground. Our offerings make on-board communications simple and easy to manage, with solutions built for any size aircraft performing any mission, with any service provider.

At the time of writing this equipment uses geostationary satellite networks and large high-gain antennas, however in the future this capability will also be provided by Iridium Communications at a lower price-point. It may even use its own terrestrial based network – such as services offered by Gogo, SmartSky and AirSky.

Other manufacturers of operational equipment for this market include Rockwell Collins and Honeywell. The LCS offers a light and efficient SATCOM solution. Beyond standard SATCOM voice and datalink usage, the LCS will unlock the use of new connected applications such as Mission+ from NAVBLUE (an Airbus subsidiary).

Airlines will have new means to optimize their operations. Typical users of this equipment are private owners, tourism/charter operators, and some first-responders. They typically fly small fixed wing and single engine aircraft and helicopters. Well-known providers of this equipment are SpiderTracks, Blue Sky Networks, Guardian Mobility, and TracPlus Global.

Installation is cheap and there are no installation certification requirements for this type of equipment. Today, satellite constellation technology enables more throughput, taking into account regulatory requirements and the growing number of customers. However, while airlines need and expect more connected IP-based applications, it is fundamental to ensure aircraft systems remain protected.

All cockpit communications to/from aircraft are routed through Satellite Service Providers (SSP) infrastructures (Satellite, Gateway/GES). Today two SSP are recognized to be used by commercial aviation to exchange aircraft cockpit data with ground users: Inmarsat and Iridium.

Since the early stages of commercial aviation, and in order to enhance safety, regulations have required long-range communication means for flying over oceanic and remote areas. Initially performed exclusively with HF voice communication, the cockpit SATCOM which operates in the L-band radio frequency is now recognized as an alternative means of communication with the ATC (Air Traffic Control) or AOC (Airline Operation Center).

For continental areas such as Europe, VHF is mainly used thanks to a widely deployed, but increasingly congested, VHF ground network. Flight crew can operate and control LCS with the new radio control means RMP (Radio Management Panel, cf FAST article Cockpit communication - new-generation audio system) or with the legacy MCDU (Multipurpose Control and Display Unit) and ACP (Audio Control Panel)

, according to aircraft configuration. In the FCI context, SATCOM, together with the terrestrial communication systems, will enable the future SATCOM concepts supporting IPS communications and Performance Class A, which are being developed in the context of the SESAR, NextGen and CARATS ATM modernization programs.

Viasat Dve To Improve Satellite Connectivity For Military Isr Aircraft -  Avionics International

The focus in SESAR is primarily on safety of life communications and also in Airline Operational Control (AOC) SATCOM communications, as both are allowed to operate in the same frequency bands under the AMS(R)S ITU frequency allocation.

Pricing is around the $1,500 - $3,000 US mark with additional operational costs for the tracking service in the vicinity of $50 - $150 US/month. Some manufacturers also have a built-in cellular network option that complements the satellite technology.

The cellular option is a cost-saving measure and used when in-range of cellular networks. During the development phase of the LCS, flight tests were conducted on several Airbus aircraft types. More than 70 hours of dedicated flight were performed.

The objective was mainly to check the correct behavior of the SATCOM interconnected to the avionics, ensure there was no interference with other Communication/Navigation/Surveillance systems, evaluate the end-to-end connectivity performance through satellite space and also the ground segment during all

phases of flight and all flight envelope of the aircraft. Flight crew workload and Human Machine interface were also evaluated. This equipment is typically used by first responder aircraft and the military and manufacturers include, Blue Sky Networks, Flightcell, Honeywell and Latitude/SkyTrac.

A typical installation will take 2-3 days and will be installed under a Supplementary Type Certificate (STC) or an engineering modification. At EUROCONTROL, we support the technical, operational and standardization activities in SESAR2020 Wave 2 PJ.14 Solution 107 "Future Satellite Communications Datalink".

In particular, EUROCONTROL is an active contributor to ICAO Working Groups in the update of the SATCOM standards (SARPs and Manual) to include provisions for the future SATCOM systems, meeting SATCOM Performance Class B and in the future SATCOM Performance Class A systems supporting ATS Baseline

2 (B2) and B3 service requirements. EUROCONTROL is also a participant in EUROCAE WG-82 activities aiming to develop ATN/IPS and Voice over IP capability for future SATCOM. Exchanges with ATC are essential to prevent collisions, ensure and optimize the traffic in controlled airspace.

Aircraft automatically report their position (ADS-C) and also exchange data via pre-formatted messages (CPDLC) to allow controllers to safely guide aircraft to their destination (routine operations). Both functions are part of FANS application (FANS 1/A in oceanic and remote areas).

Flight crew can contact or be contacted by ground control by voice means (SATVOICE function) in distress, emergency or flight safety situations (non-routine operation). Such communication exchanges supporting safe operation of aircraft are part of the "Aircraft Control Domain" (ACD).

These critical communications must demonstrate minimum end-to-end performance known as PBCS (Performance-Based Communication and Surveillance). PBCS defines a minimum performance to allow an aircraft to use optimized routes (therefore allowing fuel savings). Passengers and flight crews can enjoy the luxuries of high-speed data connectivity powered by our global satellite communications.

From the sky to the ground, our communication platforms are deployed worldwide in all types of aircraft so people can stay in touch. In some cases, cellular technology supplements the satellite technology, providing operational cost benefits and broadband data for email and internet access.

Pricing is around the $10,000 - $20,000 US mark including antennas. The upper end of this price bracket includes add-on's that include WiFi and Bluetooth™ connectivity for smart devices, or Iridium Push-To-Talk (PTT). There are additional operating costs for tracking and voice services, and they are at a similar price point to the basic tracking devices above.

There may be additional costs for satellite voice calls, but cellular calling costs are negligible. Satellite communications (SATCOM) are already today an important component of aeronautical communications, in particular for the oceanic airspace. In the future, SATCOM is expected to be equally important also for the continental airspace and become an integral part in the Future Communications Infrastructure (FCI).

In addition, evolving satellite constellations provide new SATCOM systems offering new capabilities to meet the current and future aviation communication needs. High Capacity Multi-Systems This grade provides high-end satellite equipment for high-capacity voice and high-capacity data.

There are many voice and data channels and they are accessible to multiple onboard devices. This system is typically installed in the avionics bay of a wide-body passenger jet or a business jet. Some dual-engine operational helicopters use this equipment, however that is the exception and not the norm.

Jim FAWCETT, Lead Flight Test Engineer and specialist in communications systems describes the experience: "We operated our flight test aircraft throughout the entire flight domain to ensure good SATCOM coverage even in case of manoeuvring. To ensure good geographical coverage and correct voice and data service behavior at satellite handover boundaries, we even operated our A350 on a 12-hour flight from Toulouse in France to Gander in Canada and back, without landing!

Our crew found the HMI (Human Machine Interface) intuitive and easy to use. The system behaved well and should provide a secure solution for our customers in the years ahead. Typically, thanks to the EFB (Electronic Flight Bag) live weather forecast application, the crew on a transatlantic flight can detect an unexpected approaching storm cell with potential turbulence as a complement to the onboard weather radar.

They can then call the ATC using the satellite communication system to get clearance to change the flight plan. The next Inmarsat LCS evolution under development is FANS C over SATCOM (FAST article FANS C - on page 34).

This future capability will enable the use of SATCOM for ATC datalink communications over ATN (Aeronautical Telecommunication Network). It will provide an alternative means to alleviate the European VHF datalink network, expected to be saturated in the near future, especially in high density areas, mitigating the risks of quality degradation of datalink services for ATC and AOC.

FANS C over SATCOM will enter service on A320 and A330 aircraft families and will be capable of 4D Trajectory Based Operations (new mandate from 2028). Exchanges with AOC allow airlines to support aircraft operational efficiency.

It is part of Airline Information Services Domain (AISD). Aircraft can receive and send preformatted automatic maintenance reports via the ACARS network. To support flight operations, crews can request weather data updates during flight to optimize flight path while ensuring passenger comfort (cf FAST article EFB - the new standard).

Aircraft also send maintenance reports to the ground automatically, in order to anticipate dispatch and maintenance activities after landing. Voice calls also offer the possibility for pilots to exchange operational information complementary to ACARS with their airline control centers.

Basic Tracking Devices This is typically a single device that is affixed to the glare shield with suction cups. Its main purpose is to track the position of the aircraft and send event information. This type of equipment almost certainly has a messaging capability, but no voice capability.

The tracking and messaging data is sent to and from the aircraft using the Iridium satellite network.

Aircraft Stall

Aircraft Stall

Aircraft Stall - A reed horn warning system is better suited for a high wing airplane where it is possible to locate the horn at ear level in the cockpit. It probably wouldn't be as audible in a low wing airplane where the horn would most likely be located somewhere behind the instrument panel.

At any rate, the reed horn warning system is lightweight, easy to install and to adjust. Incidentally, this same check can be used for another purpose. Just before you close and lock the hangar door, go over to your trusty stall warning lift detector and gently raise the little tab.

Aircraft Stall

Stall - How Did This Boeing 787 Perform This Near Vertical Takeoff? -  Aviation Stack Exchange

If nothing happens (no horn noise) you know positively that your Master Switch is OFF. Isn't that much easier than climbing back on the airplane for a look at the switch? The good news is that pilots can overcome stalls by focusing on two main things: the airplane's angle of attack and the airplane's speed.

How Pilots Overcome Stalls

If an airplane starts to stall mid-flight, the pilot must quickly adjust these settings to regain control of the aircraft. If the stall was caused by an incorrect angle of attack, the pilot must adjust the airplane's pitch to achieve an angle that's lower than the critical angle of attack.

If the stall was caused by a low airspeed, the pilot must accelerate the airplane to the appropriate speed. By adjusting the airplane's angle of attack and/or airspeed, pilots can overcome stalls to achieve lift again.

Stall Warning Devices? Who Needs Them? Hold on now, let's not dismiss the subject too casually. Nobody can tell whether or not a particular airplane will need some sort of stall warning device until after the airplane's stall characteristics have been experienced in flight tests.

Actually, the installation of stall strips or a stall warning horn need not be limited to aircraft that exhibit undesirable stall characteristics. Airplanes can be stalled under a variety of conditions of speed and attitude, therefore, even an airplane with normally docile stall characteristics could, under some conditions of flight, develop a beastly behavior.

The Basics Of Stalls What You Should Know

Regardless of their respective size, airplanes must stay within a certain angle to maintain lift. If they exceed this limit, their lift will decrease. This can lead to a phenomenon known as a stall. When an airplane stalls, it will no longer produce lift.

As a result, the airplane's altitude will decrease as gravity pulls it down. Pilots can prevent stalls, however, by staying above their airplane's stall speed. What is stall speed exactly, and how does it affect airplanes?

How do you determine where to locate that warning horn lift detector? One thing is certain, the stalling characteristics of an airplane cannot be precisely predicted by mathematical methods. As you know, the stalling characteristics of most any airplane are markedly different under different flight conditions of power application and flap setting.

The best guidance I can offer is to suggest that the photos accompanying this article are quite representative of such installations. A trip to the airport for a first hand viewing of lift detector installations would also be helpful.

Spins | Academic Flight

Angle Of Attack And Stall Speed What You Should Know

All airplanes have a specified stall speed. Stall speed is simply the minimum speed needed for an airplane to produce lift. If an airplane drops below its specified stall speed, it will no longer produce lift.

Stall speeds vary depending on many factors, some of which include the airplane's weight, dimensions, altitude and even the weather dimensions. Regardless, airplanes must fly faster than their respective stall speed to maintain lift. A common misconception is that stalls are attributed to a mechanical problem in an airplane.

In cars, trucks and other ground-based automobiles, an engine stall is, in fact, a mechanical problem. When an automotive engine stops turning and no longer produces power, it's called a "stall." In airplanes, however, stalls have a completely different meaning.

It is important to note that stall protection systems cannot take into account the possible effects of contaminated aerofoil surfaces and also that any such contamination may not necessarily be symmetrical in respect of the overall aircraft.

The Basics Of Stall Speed

It should also be noted that on modern Fly-By-Wire airplanes, the stall protection system has become part of a wider Flight Envelope Protection System. Even if you're unfamiliar with aviation mechanics, you've probably heard the word "stall" before.

From small single-engine rotary airplanes to massive twin- or four-engine commercial jets, stalling is a problem to which all airplanes are susceptible. During flight, an unexpected stall can pose a significant threat to the airplane and its passengers.

But the good news is that most airplanes have safety systems in place to control and eliminate stalls. Obviously, the unit cannot warn you of an impending stall if it is not working. You can minimize this risk if you include the check of the stall warning horn in your preflight inspection - you do make 'em, of course.

Simply turn on your Master Switch and walk over to the lift detector and raise that little tab and listen for the horn to go off. If you hear it you know that the unit is working.

In Conclusion

You also learn that the battery is still alive. The Angle of Attack of an aerofoil - the incidence of the wing to the incident airflow - is not the same as the pitch attitude of the aircraft as displayed on the corresponding primary flight instrument and many aircraft do not have an instrument which displays angle of attack

. However, when flying straight and level with a particular aircraft mass and prevailing density altitude, for every wing angle of attack there is a corresponding indicated air speed. Because of this, the indicated airspeed at which an aircraft has been shown to stall in given circumstances is determined during aircraft certification and included in the AFM.

A Stall Is Caused When The Critical Angle Of Attack, Or Aoa, Is Exceeded.  The Angle Of Attack Is The Angle Betwee… | Plane Spotter, Aviation  Photography, Lift Force

This indicated speed, Vs, provides a fundamental reference for all other AFM airplane performance calculations which involve indicated airspeed and helps define the Flight Envelope for each aircraft type and variant. Stall Strips Stall strips are located where they are on the wing because the builder (manufacturer) has determined that that is where they work best.

. . for a particular airplane. The sharp edge of a stall strip is intended to disturb the smooth flow of air over the wing surface in the area where it is installed. . . and do it just before the rest of the wing begins to stall.

This disturbed flow or burbling will cause the airplane to shake or shudder slightly, a fair enough warning for any pilot that a stalled attitude is being approached. If set properly, the stall strips will do their thing about 5-10 mph above the normal stall speed of the aircraft.

ANY AIRPLANE THAT does not give the pilot unmistakable warning (buffeting, shaking, etc.) that a complete stall is developing is a dangerous airplane to fly. . . no matter how delightful its other flight characteristics might be.

An airplane like that is dangerous to any pilot in the traffic pattern where a sudden distraction or a miscalculation due to a momentary lapse of attention can lead to a stall, especially while "turning final" (an ominous term, isn't it?)

. A stall occurs when the angle of attack of an aerofoil exceeds the value which creates maximum lift as a consequence of airflow across it. This angle varies very little in response to the cross section of the (clean) aerofoil and is typically around 15°.

At the stall, the airflow across the upper cambered surface ceases to flow smoothly and in contact with the upper surface and becomes turbulent, thus greatly reducing lift and increasing drag. Changing the effective configuration of a wing by the deployment of leading edge or trailing edge devices will directly alter the angle of attack at which an aerofoil stalls.

However, all this assumes a clean wing and for any aerofoil, contamination of the normally smooth surface by frozen deposits will result in a change to the angle of attack at which a stall will occur.

The lift detector unit is mounted in the leading edge of the wing, usually in an area of ​​undisturbed air flow. This, of course, means outside the propeller disc area. The lift detector will not react to the normal airflow over the wing, regardless of the airspeed.

However, anytime the airflow is altered, as when the angle of attack increases in an approach to a stall, the disrupted airflow will force the lift detector upwards and activate the relay to which it is attached.

Airplane Stalls

This sends an electrical current to the warning buzzer and/or light. The Reed Horn Stall Warning System Here is an improvement over the lift detector type warning horn. This system will be found on Cessnas manufactured after the late 1970's.

It, too, is operated by a change in airflow over the wing's leading edge. This device does look like the older lift detector warning horn installation except for the impression it gives that some vandal has pulled the flapper (lift detector) out leaving only a vacant rectangular opening.

This appearance is misleading. Actually, that vacant port is a tip-off that a simplified and more economical stall warning reed horn warning system is installed. The adjustable plate mentioned earlier controls the speed at which the horn blowing takes place.

Moving the plate upwards will cause the horn to actuate at a higher airspeed. Moving the plate downward conversely causes it to blow at a slower speed. The reed horn stall warning systems adjustable plate is installed in approximately the same position on the leading edge as the other model would be.

As previously mentioned, stalls occur when the angle at which an airplane flies exceeds a limit. Being that angle attack is responsible for stalls, you might be wondering why speed is important. Well, speed affects an airplane's angle of attack.

If an airplane flies slowly, it will require a greater angle of attack to produce lift. Eventually, the required angle of attack will be so excessive that the airplane won't generate lift. Therefore, pilots use stall speed to ensure that they don't slow down enough that it causes a loss of lift.

When installing stall strips, a cardboard template duplicating the first 6-8" of the leading edge portion of your wing can be most useful. Cut a triangular notch for the stall strip where you want it positioned. The template will help assure a symmetrical installation

on both wings. Here's some guidance. If your airplane exhibits a marked buffeting or a shaking sensation felt through the airframe or the control system, you don't really need a stall warning device. If your airplane requires a very pronounced and deliberate rearward pull force on the control stick to make it stall, you don't need a stall warning device.

On the other hand, if your airplane, without warning, characteristically tucks its nose and/or exhibits a very pronounced rolling tendency anytime you let your airspeed get a bit low, you have an airplane that must be considered to have dangerous stall characteristics.

Such an airplane should be re-rigged and/or equipped with stall strips or at least a stall warning horn. While most stalls are attributed to an angle of attack that's greater than the critical angle of attack, this phenomenon may also occur if the airplane's speed is too low.

Technique: Power-On Stall - Aopa

With that said, the pitch of an airplane can also affect whether airspeed will cause a stall. An airplane gaining altitude at a high pitch may stall at a lower airspeed than an airplane flying horizontally at a flat pitch.

Well, how useful is this unit? It will warn you of an approaching stall provided it is properly installed. This warning will come regardless of the aircraft's speed or type of maneuver in progress. If you deliberately continue to invite a stall, the warning horn will continue its irritating blare as long as the wing is in an abnormally high angle of attack and the flow of air over the device is disrupted.

Attach your stall strips initially with masking tape or gray duct tape but do not fit the strips into the wing. Your objective is to maintain a sharp triangular cross section. Next, make a flight check of the newly installed strips.

The result you want is a slight buffeting or vibration in the airplane or the controls. This should ideally occur about 5-10 mph before the stall occurs. Sitting comfortably in your easy chair you know that trying to raise the nose of a stalled aircraft is a suicidal act.

The correct action is to pop the nose down, isn't it? It seems we all know that except for the guys who have spun in. When an airplane stalls, it's no longer able to produce lift.

This is not due to a mechanical problem, such as a failing engine. Rather, airplanes experience stalls when the angle at which they enter the wind current is greater than the critical angle of attack. When this occurs, there's an insufficient amount of air traveling under the airplane's wings to keep it up.

As a result, the airplane will drop, thereby reducing its altitude, until the angle of attack is correctly adjusted. You can check out the horn operation on the ground by covering the opening in the adjustable plate with a cloth, putting your mouth to it, and inhaling to create a slight suction in the system.

This intimate action causes the horn to make its characteristically audible raspberry. The simple construction of the device and the equally simple installation is very much evident. The external part of this lightweight system fastens to the leading edge of the wing by means of an adjustable slotted plate that can be adjusted up or down about 3/16". Behind the adjustable plate is a scoop-like piece to which a bug screen

is affixed. This, in turn, is attached to an adapter to which a plastic tube is fitted. The plastic tube, being very flexible, is easily routed up to the wing root where a plastic reed horn is stuck into the other end of the

plastic tube. That is all there is to the system. No electric wiring or power is needed. As for the stall warning horn, it is nothing more than a simple reed type horn... something like a party noise maker.

Stalls And Angle Of Attack: A Very Important Relationship - Flytime.ca

The Lift Detector Stall Warning Horn This is the device that has been around for a long time. It consists of a horn mounted in the cockpit (usually behind the instrument panel) and an electrical relay unit operated mechanically by changes in the slipstream.

This unit requires an electrical system (12 volts or 24 volts DC). However important such devices might be, a newly certified homebuilt is not likely to be similarly equipped. It's not that the homebuilders have anything against stall warning devices;

it is just that they assume the things cost too much and that they cannot be accurately installed. . . for the initial flight test anyway. Well, although the aural stall warning horn devices are moderately expensive, the stall strips are not.

Certainly, one such device is better than none - if needed. As for the argument that the stall warning device may not be accurately installed for the first flight, that is a logical enough conclusion. After all homebuilts do feature a wide range of airfoil types and wing configurations.

And, since plans rarely, if ever, detail the installation of stall warning devices, the builder is on his own. . . with a number of questions to resolve. One moment the pilot is in complete control and the next he is staring at the ground in shocked disbelief.

He realizes, too late, that he allowed the airplane to stall! In spite of his frantic effort to raise the nose by yanking back on the control stick so hard the elevator hits the stops, the nose down pitching remains uncontrollable, as uncontrollable as the sudden wing drop.

The accompanying rapid loss of altitude becomes excessive. If the airplane's altitude is too low and its recovery is too slow, too bad! (That's no way to recover from a stall, is it?) Stall speed refers to the minimum speed at which an airplane must fly to produce lift.

Going back to the basics of aerospace dynamics 101, airplanes produce lift in response to the air moving over their wings. At high speeds, the fast-moving air "lifts" the airplane so that it doesn't fall to the ground.

At low speeds, on the other hand, the lack of air movement will result in little or no lift being produced, in which case the airplane may stall. Stall strips, on the other hand, when properly fabricated and installed can serve to warn you of an impending stall and, to a degree, may even alter the stall characteristics of the airplane.

So, although stall strips are less expensive and easier to install, believe it or not, they are, in my estimation, more functional than are the aural warning horn systems. This may explain why manufacturers often equip their aircraft with both systems.

Just where should the stall warning device be located? How far from the wing root? How high or how low on the leading edge should it be? Is it safe to cut a hole in the leading edge and to gouge out a rectangular opening large enough for the stall warning horn relay?

With such seemingly unanswerable questions and the unattractive price of a new stall warning unit, it is not surprising that the installation of an aural stall warning unit is not a high priority item with homebuilders.
