ADME 2.4 SURFACE MOVEMENT GUIDANCE & CONTROL SYSTEMS

At their simplest these may consist of ground markings and stop & go lights. More sophisticated systems will incorporate taxiway centre line lighting and stopbars which can delineate the cleared route of aircraft. Where a need exists, surface movement radar … Continued

ADME 2.3 VISUAL OBSERVATION & NEW AERODROME CONTROL TOWER CONCEPTS

IFATCA Policy is: Visual observation in ATM is defined as: Observation through direct eyesight of objects situated within the line of sight of the observer possibly enhanced by binoculars. An Aerodrome Control Tower is a unit established to provide … Continued

ADME 2.2 LAND AND HOLD SHORT OPERATIONS (LAHSO)

IFATCA Policy is: IFATCA opposes LAHSO unless the following concerns have been satisfactorily addressed: The lack of exact requirements for what are acceptable airport and runway configurations; The “hold short point” is not always easily identifiable to the pilots. … 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 1.18 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 1.17 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 1.16 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 1.15 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 1.14 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 1.13 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
