Safran / Honeywell demonstrates electric taxiing system on an Airbus A320

While the Paris Air Show is famous for its aerial displays, a more down-to-earth demonstration at Le Bourget Airport is showing the way for the increasingly electric future of aviation.

A modified A320 showed off its moves on the runway this week, powered by its environmentally-friendly electric green taxiing system (EGTS), which was developed by EGTS International – a joint venture of Safran and Honeywell. One wheel on each main gear is equipped with an electric motor, reduction gearbox and clutch assembly to drive the aircraft during taxi operations, with power electronics and system controllers allowing pilots to control its speed and direction.

The EGTS is powered by the aircraft’s auxiliary power unit (APU) generator, allowing the aircraft to move around the tarmac without using its main engines. This will improve airline operating efficiency during taxi operations and reduce fuel consumption by up to four per cent per flight cycle.
