As part of on-going research and development into future technology options, Airbus has signed a memorandum of understanding (MoU) with EGTS International, a joint venture company between Safran and Honeywell Aerospace, to further develop and evaluate an autonomous electric pushback and taxiing solution for the A320 Family. The agreement marks the selection of EGTS International’s Electric Green Taxiing System to be evaluated as a new option on the A320 Family – referred to by Airbus as eTaxi. This option would allow the aircraft to push-back from the gate without a tug, taxi-out to the runway, and return to the gate after landing without operating the main engines. eTaxi will use the aircraft’s Auxiliary Power Unit (APU) to power electric motors fitted to the main landing gear wheels. The architecture will include the ability for pilots to keep full control from the cockpit over their aircraft’s speed and direction during taxi operations.
