Abstract
Several concepts are being developed to enable aircraft ground movement without any aircraft engine running. Such concepts can be electrically-driven devices that connect and disconnect from the aircraft (such as tugs) or a motor permanently fitted to the nose or main landing gear.
Whilst IFALPA supports technical developments that can help reducing noise, emissions and fuel, it is essential to guarantee a high level of safety during taxiing, which is a critical phase of flight. The Federation believes that safe and sustainable All Engine-Out Taxi (AEOT) can only be achieved provided the following general, design and operational requirements are met
