3 Systems for Green Operation: the concepts Pillar 1: Management of Aircraft Energy (MAE) The use of all (more) -electric equipment system architectures from electrical generation and distribution to electrical aircraft systems. Thermal managementwill address many levels, particularly relating to electric aircraft, from hot spots in large power electronics to motor drive system cooling, to overall aircraft solutions. Pillar 2: Management of Trajectory and Mission (MTM) The silent and agile aircraftwill generate a reduced noise footprint during approach and departure by flying optimised trajectories. Aircraft will be able to fly a green missionfrom start to finish, thanks to technologies which allow to avoid fuel consuming meteorological hazards Smart Operations on Ground
