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 1.01 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 1.02 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

AAS 1.03 MODE S DEVELOPMENT

Mode S has been established by ICAO as the standard for SSR surveillance due to those performance and functional limitations of the present system which are becoming increasingly significant. Whilst the initial implementation emphasis is on surveillance, Mode S also … Continued

AAS 1.19 OPERATIONAL USE OF DOWN-LINK AIRCRAFT PARAMETERS (DAPS)

Many parameters are available from Mode S, ADS-B UAT (Universal Access Transceiver) and ADS-B ES (Extended Squitter) i.e. (Mach number, indicated airspeed, vertical speed, heading etc.) There are no provisions about how or if there a need to check them … Continued

AAS 1.04 REQUIRED NAVIGATION PERFORMANCE (RNP) and AREA NAVIGATION (RNAV)

Area Navigation (RNAV) is defined as a method of navigation which permits aircraft operation on any desired flight path within the coverage of station-referenced navigation aids or within the limits of the capability of self contained aids, or a combination … Continued
