1、wRNEST use cases:GEESE and CICONIAEUROCONTROL Showcase Summit:Smart Sustainable Skies 2025Zoltn BazsAviation Sustainability Unit,EUROCONTROLGEESE concept in a nutshell Wake Energy Retrieval fuel burn savings achieved through pairing aircraft together and flying in formation,with Follower 1.5NM behin

2、d the Leader Expected fuel burn reduction for the Follower is in the region of 5%but depends on many factors e.g.altitude and aircraft type Pairings are computed by Pairing Assistance Tool by Airbus Scaling the concept up depends on the net benefit(fuel burn benefit from formation flying versus fuel
