AAS 1.11 “FLY-BY” AND “FLY-OVER” WAYPOINTS

The concept of “fly-by” and “flyover” waypoints is integral to RNAV and as such has been in existence for quite some time. As Performance Based Navigation is being increasingly used to reduce the distances between routes to a minimum, air … Continued

AAS 1.12 AIRCRAFT FLIGHT MANAGEMENT SYSTEMS

Aircraft Flight Management Systems are in place on almost all transport aircraft in use today. These systems have been developed in order to assist the operation of the aircraft and to improve safety. ATM considerations have generally been a by-product … Continued

AAS 1.13 DETERMINING OPERATIONS READINESS OF NEW ATM SYSTEMS

Modern ATM systems are more and more complex. Safety critical tasks such as Radar Data Processing or Flight Data Processing rely on complex software packages while the increasing volume of air traffic makes the ATM system more and more dependent … Continued

AAS 1.14 SPACE-BASED AUTOMATIC DEPENDENT SURVEILLANCE – BROADCAST

Aireon LLC proposes to use satellites to relay Automatic Dependent Surveillance – Broadcast (ADSB) data from suitably equipped aircraft to Air Traffic Service Units (ATSUs) and provide surveillance coverage in what the consortium calls ‘near real-time’ across 100% of the … Continued

AAS 1.15 CONCEPT OF GNSS-BASED ALTITUDE

The use of pressure-based altimeters to determine aircraft altitude has been universal across the globe for most of aviation history. This policy examines alternatives provided by Global Navigation Satellite System (GNSS) technologies. IFATCA Policy is: IFATCA encourages development of technologies … Continued

AAS 1.16 FUTURE WEATHER DISTRIBUTION

Aviation Weather Information is and has been critical for the advances in flight safety. However, there is room for improvement, not the least due to technological advances. IFATCA Policy is: IFATCA encourages the development and use of aircraft-derived meteorological data … Continued

AAS 1.1 AIRBORNE COLLISION AVOIDANCE SYSTEMS (ACAS)

IFATCA Policy is: IFATCA fully supports and encourages the development and operation of airborne anti- collision systems. The primary means of collision avoidance for flights for which a separation service is set-up shall be the air traffic control system. This … Continued

AAS 1.17 SPACE WEATHER

Space weather can affect satellite-based navigation and communication systems and present a health risk to aircrew and passengers. In addition, the difficulty of forecasting the occurrence and severity of space weather events accurately and the dissemination of that information present … Continued

AAS 1.2 AUTOMATIC DEPENDENT SURVEILLANCE (ADS)

IFATCA Policy is: Before an ADS service is introduced into operational service, the necessary system components to provide a control service and to support the control task shall be in place. Only pertinent and useful flight data should be … Continued

AAS 1.18 MULTIPLE DELAY ABSORPTION PROGRAMS

As air traffic counts around the world increase, the demand on airports is growing exponentially. In order to facilitate safe and orderly operations at aerodromes, ANSPs are applying spacing methods deeper and deeper into the en route environment. The application … Continued
