AAS 1.08 4D TRAJECTORY CONCEPTS/MANAGEMENT

IFATCA Policy is: Implementation of 4D trajectory management requires appropriately designed airspace. See: Resolution B8, B9 – WP 91 – Toronto 2017, Resolution B7 – WP58 – Virtual 2022 See also: WP 86 – Arusha 2008

AAS 1.24 ATM SYSTEMS INTEROPERABILITY

IFATCA Policy is: Updates, upgrades, design and development of an ATM system shall: endeavour to increase, or at a minimum maintain, interoperability between neighbouring and global ATM systems to support seamless cross-border operations; endeavour to reduce, or at a minimum … Continued

AAS 1.09 REMOVAL OF GROUND BASED AIDS

The implementation of GNSS is precipitating the removal of certain ground based navigation aids. IFATCA is concerned that as these GNSS systems are subject to natural temporary degradation and unserviceabilities that there should not be a reliance on a sole … Continued

AAS 1.25 GNSS RFI

IFATCA Provisional Policy is: Globally harmonised phraseology shall be developed to report both GNSS RFI and false EGPWS alerts. See: WP 98 – Abu Dhabi 2025

AAS 1.10 OPERATIONAL USE OF UNMANNED AIRCRAFT (UA)

ATC should not have to apply different rules or work with different criteria in order to handle UA. From the air traffic controller’s perspective, the provision of ATS to an UA shall be transparent. This includes all stages of the … Continued

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
