With these objectives we intend to address ATC aspects with regards to the whole air traffic:
New airspace structures are investigated, which impacts all aircraft and hence the air traffic.
GreAT will enhance controller tools for arrival, departure and surface management to optimize the traffic situation as a whole, not just single flights.
For evaluation reasons, it is necessary to use scenarios in which individual flights can be tracked from gate to gate, since fuel consumption occurs on board of each single aircraft.
ATC aspects are fully covered on airport surface and TMA as background traffic is also simulated.
TMA optimisation strategies are applied to whole traffic, not just to flights from and to airports of the airport pair.
Less optimization potential is expected for long-haul flights, while ATC-induced maneuvers play a smaller role than for short-haul flights. In terms of long-haul flights, general flight path planning is more important.
