AUO-0806 — Incorporation of Non-Autonomous Engine-off Taxiing into surface operations

Fuel consumption and safety are improved during airport surface operations thanks to Taxi-out and Taxi-in phases being done through non-autonomous engine off taxiing used from the gate to the holding point before line up (i.e. for push back and taxi out) and from the runway exit to the gate (i.e. for taxi in to in block). This may be realised with the aircraft using other external means to taxi (e.g. towing trucks, taxibot).

Such green taxiing will help the airport improving performance related to environmental impact since gains on environment will be substantial (reducing fuel consumption by the aircraft with concomitant decrease in CO2 and NOx emissions whilst keeping down noise around the airport). Engine off taxi could provide a significant safety improvement as the number of FOD (Foreign Object Debris) and blast damages during ground operations can be significantly reduced. Most FOD and blast damages are typically in the area close to the gate and engine off taxi could eliminate both risks.
