Israeli flag-carrier El Al is to become an initial customer for an electric nose-gear drive system, designed to enable aircraft to taxi without the use of engines.
El Al has signed a letter of intent under which it will "obtain a substantial part of the initial production" of the WheelTug drive systems, said WheelTug.
The Israeli carrier will install the equipment on modern-variant Boeing 737 aircraft, the type on which early development of the sytem has concentrated.
WheelTug said that the agreement is subject to "financial and operational feasibility checks" as well as regulatory approvals.
The nose-gear drive has been developed to reduce fuel-burn by enabling aircraft to push back and taxi - to and from the runway - under electric power rather than through the engine thrust.
Not only does this save fuel but the aircraft is put at less risk of foreign object damage, WheelTug said. It added that the system could generate "substantial" savings in operating expenditure per aircraft.
WheelTug is planning to expand the system to other commercial types.
