Orthogon Extended Arrival Manager (E-AMAN)
The SESAR Extended Arrival Management (E-AMAN) concept allows air traffic controllers to meter traffic into a busy Terminal Movement Area (TMA) from far out in the en-route airspace. This is feasible by extending the AMAN’s operational horizon from the airspace close to the airport to a horizon further upstream, in adjacent en-route airspace. Typically, an E-AMAN solution is implemented using a SWIM-compliant information exchange infrastructure that delivers AMAN output information (e.g., target times, time to lose/time to gain advisories) to controllers upstream.
With an E-AMAN implemented, en-route controllers can then inform aircraft pilots to adjust their speed before their Top of Descent, thus reducing the amount of time the aircraft spends in the TMA. This leads to a reduction of time spent in holding stacks in the destination TMA. E-AMAN is also featured in the Aviation System Block Upgrade (ASBU), an ATM modernization strategy introduced by the International Civil Aviation Organization (ICAO).
