Departure Optimisation

Optimisation for departure profiles is a developing ANS enhancement. Procedures for the fuel and emissions optimisation of departures have yet to be defined within INSPIRE. Procedures are expected to include optimise departure to facilitate unconstrained climb to cruise level and track to route start point, and manipulate taxi and departure time to optimise oceanic entry altitude and position in the enroute sequence.

Departure optimisation procedures are expected to substantially improve the fuel and emissions efficiency of aircraft during the climb-to-cruise portion of flight by minimising low altitude vectoring and the need to level-off at interim altitudes.
