In an effort to improve aviation communication, navigation, surveillance, and air traffic management ICAO standards for a future system were created, this integrated system is known as the Future Air Navigation System FANS and allows controllers to play a more passive monitoring role through the use of increased automation and satellite based navigation. Previously, flight crews would be notified of the system being used to calculate the position radios, or inertial systems alone.

This involves a transition from inertial navigation to satellite navigation using the GPS satellites. The development of the FANS-capable aircraft systems proceeded simultaneously with the ATC ground system improvements necessary to make it work.

These contracts are set up between ATC and the aircraft’s systems, so that the flight crew has surocae workload associated with set-up.

The current standard for message delivery is under 60 seconds one way. The application is known as ADS-C automatic dependent surveillance, contract. Aircraft are operated using two major methods; positive control and procedural control. If market demand pushes airlines to operate at the same time on a given route, this can lead to airspace congestion, which is handled by delaying departures or separating the airplanes by altitude.

This is because the air traffic controller can recognize problems and issue corrective directions to multiple airplanes in a timely fashion. Positive control is used in areas which have radar and so ed–120 commonly referred to as Radar control.

In this system, an air traffic controller can set up a “contract” software arrangement with the airplane’s navigational system, to automatically send a position report on a specified periodic basis — every 5 minutes, for example. This involves the transition from voice reports based on inertial position to automatic digital reports. Because of the deterministic nature of the GPS satellites constellation geometrythe navigation systems can calculate the worst case error based on the number of satellites tuned and the geometry of those satellites.


The final report was released in with a plan released in The latter can lead to very inefficient operation due to longer flying times and increased fuel burn. The HF wurocae operator can also euroxae saturated with requests for communication. The voice quality of rd-120 connection is often poor, leading to repeated messages.

Future Air Navigation System

Procedural control is used in areas oceanic or land which do not have radar. These trials demonstrated the potential benefits to the euroce and airspace managers. Commercial aircraft operators typically get their long haul fleet connected and have dedicated personnel to monitor and maintain the satellite and ground link while business aircraft and military aircraft operators contact companies like AirSatOne to commission the system for the first time, conduct functionality testing and to provide ongoing support.

These procedures reduce the number of airplanes which can operate in a given airspace.

During these trials, airplanes installed applications in their ACARS units which would automatically report positions. Air traffic control’s ability to monitor aircraft was being rapidly outpaced by the growth of flight as a mode of travel.

Separation standards are what determine the number of airplanes which can occupy a certain volume of airspace. This allowed other application improvements.

Because the position of the aircraft is updated frequently and VHF voice contact timely, separation standards the distance by which one aircraft must be separated from another are less. The communications include air traffic control clearances, pilot requests and position reporting. The INS systems have error introduced by drifting after initial alignment. All other airspace users must be ICAO compliant. The members include airframe manufacturers, avionics suppliers, communication service providers, and air navigation service providers.


HF radio communication involves contacting an HF operator who then transcribes the message and sends it to the appropriate ATC service provider. This method uses time-based procedures to keep aircraft separated.


It was followed by the first commercial flight from Sydney to Los Angeles on June The purpose of this team is to monitor the performance ed120 the end-to-end system, identify problems, assign problems and assure they are solved. The controller “sees” the airplanes in the control area and uses VHF voice to provide instructions to the flight crews to ensure separation.

Since this time, wurocae regions have initiated FIT groups. Boeing also extended the range of aircraft supported to include the Boeing and The controller can also set up a deviation contract, which would automatically send a position report if a certain lateral deviation was exceeded. This was based on the early ICAO technical work for automatic dependent surveillance ADS and controller—pilot data link communications CPDLCand sd-120 as a software package on the flight management computer of the Boeing They can select from a set of messages and send communications to the airplane.

Boeing worked with the airlines to develop a standard which would control the interface between FANS-capable airplanes and air traffic service providers. The deployment of FANS-1 was originally justified by improving route choice and thereby reducing fuel burn.

This allows the flight crew euroxae select from a menu of standard ATC communications, send the message, and receive a response. The Future Air Navigation System FANS is an avionics system which provides direct data link communication between the pilot and the air traffic controller. This also introduced the concept of actual navigation performance ANP.

The FANS concept was developed to improve the safety and euurocae of airplanes operating under procedural control. A peer application exists on the ground for the Air Traffic Controller.
