The mysterious case of the disappearing electric nosewheels


Fitting electric nosewheels to aircraft could reduce weight and improve efficiency – so where are they? Aircraft ground manoeuvring wastes energy. With gas turbines running inefficiently at minimum power while taxiing, or while just waiting for a slot, a typical A320/737 will consume 600 kgs of kerosene every day of …
