PARIS--Commercial aircraft builder Airbus said Wednesday it will work with aviation suppliers Safran SA (SAF.FR) of
France and Honeywell Inc. ( HON ) of the U.S. to help them develop a system that will allow airliners to push back from an
airport ramp and taxi to and from runways using electric motors in their wheels, without using their jet engines.
Safran and Honeywell have been developing the system that promises to cut fuel consumption, save time and reduce
taxiing-related emissions substantially. Airbus's backing gives a strong endorsement for the Electric Green Taxiing
System, which Airbus will call eTaxi.
The system uses an aircraft's auxiliary power unit to power electric motors fitted to the main landing gear wheels.
Pilots retain full control from the cockpit over their aircraft's speed and direction during taxi operations. The
system's developers estimate it could reduce fuel consumption and carbon dioxide emissions on an average trip by around
Airbus, a division of European Aeronautic Defence & Space Co. (EAD.FR), intends to join EGTS International, the
existing joint venture between Honeywell and Safran. The partners will evaluate the system's potential as an option for
the Airbus A320 family of short to medium-range single-aisle aircraft that could be installed during manufacture, or
retrofitted to existing aircraft.
The system was first shown in public at this year's Paris Air Show.
