Description

Extended AMAN (E-AMAN), sometimes referred to as Cross-border AMAN (XMAN) is an operational procedure which aims to improve and optimise arrival management operations for major airports. The main concept is to reduce aircraft holding time at congested airports by reducing their cruising speed during the final en-route phase of flight, several hundred (usually 180-200) nautical miles away from the airport.

E-AMAN allows for the sequencing of arrival traffic earlier, by extending the AMAN horizon from the airspace close to the airport to further upstream and so allowing more smooth traffic management. Controllers in the upstream sectors, which may be in a different control centre or even a different functional airspace block (FAB), obtain system advisories to support an earlier pre-sequencing of aircraft. Controllers implement those advisories by, for example, instructing pilots to adjust the aircraft speed along the descent or even before top-of-descent, thus reducing the need for holding and decreasing fuel consumption.
