Environmental Impact Optimisation of Flight Plans in a Fixed and Free Route network

Efforts to minimise the environmental impact of aviation can be implemented at several levels including electric green taxiing systems, novel propulsion systems, jet fuels, improvements in aircraft efficiency and optimisation of climb profiles. In this paper, we address the optimisation of flight plans in a route network considering operational...

Fuel Inefficiency Characterisation and Assessment due to Early Execution of Top of Descents: A Case Study for Amsterdam-Schiphol Terminal Airspace using ADS-B data

The vertical trajectory plan (altitude and speed) corresponding to the descent phase of a modern airliner is computed by the on-board flight management system while the aircraft is still in cruise. As long as the constraints on the arrival procedure allow, this system plans for an idle descent and the exact location of the (optimal) top of...
