L-3 Communications and Crane Aerospace & Electronics announced on the first day of Farnborough International 2012 that they have reached an agreement to develop and market the GreenTaxi electric taxi system.

It uses the airliner’s auxiliary power unit to run an electric motor mounted in the aircraft’s landing gear to directly turn the wheel, allowing it to taxi without using thrust from the engines. This has several benefits, as it significantly reduces fuel burn on the ground and thus pollution, lowers noise levels and decreases the wear on the aircraft’s engines and brakes.

L-3 demonstrated its GreenTaxi technology over four days in December last year, when it was used to taxi a Lufthansa Airbus A320 around Frankfurt Airport in Germany.
