Departure Optimisation

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

Optimisation for departure profiles include procedures to facilitate unconstrained climb to cruise level and track to route start point, and the manipulation of 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.
