Industrial Research & Validation for Aviation Green Deal


To achieve the expected outcomes, all or some of the following should be addressed.

  • Eco-friendly trajectories. When specific conditions are met – typically traffic conditions – an area can be declared eco-friendly by ATC. Eco-friendly operations are implemented with the aim of minimising the flight environmental footprint. Such implementation relies typically on improved collaboration between pilot and controller and/or between controllers in the planning and execution of the flight. Increased flexibility in the management of the flight makes it possible to optimise the flight profile to improve environmental performance. The targeted flexibility may include free lateral or vertical route deviation (without the need to require a new route clearance) for flight optimisation purposes, so that aircraft can, for example, be cleared to cruise at any fixed geometric altitude between two flight levels (thereby avoiding the climb and descent required to maintain a fixed ba
