AAS 1.06 DATALINK APPLICATIONS – THE USE OF LOGICAL ACKNOWLEDGEMENT (LACK)

There are situations present within the ATN CPDLC SARPs in which the use of LACKs is necessary to have the system perform in an operationally acceptable way. However, the deployment of such systems as FANS 1/A does not utilise this … Continued

AAS 1.22 RPAS ASSUMPTIONS

IFATCA Policy is: The RPAS Operator or the Remote Pilot shall notify ATS only that the RPAS has entered the Lost C2 Link state or that the nominal state has been re-established after a C2 Link Lost. ATCOs shall … Continued

AAS 1.07 DISPLAY OF GNSS STATUS TO ATC

When any failure to the GNSS occurs, it is to be expected that some aircraft will fail to meet the RNP and require special action to be taken, while others will be able to continue to meet the RNP. It … Continued

AAS 1.23 SYSTEM-BASED AIR TRAFFIC CONTROL LICENCE CONCEPT

IFATCA Provisional Policy is: IFATCA does not support ATC licensing concepts under which ATCOs are authorised to provide an ATC service based solely on the automation, equipment and/or systems utilised, because the contribution of ATCO skills and knowledge to the … Continued

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 1.09 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 1.10 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
