Airbus engineers have patented a taxiing system using electrically driven wheels for its A320 family, which includes the Airbus Corporate Jet, to reduce fuel consumption during ground operations at airports and allow autonomous push-backs. EADS says the system uses electric “actuators” powered by the aircraft’s auxiliary power unit to drive the landing gear wheels. Fuel consumption is expected to be five times less using the APU compared to using engine power — saving as much as 200 kg of ...
