PCTI recently supplied a very innovative ground power solution to the Air Force called the Hybrid Electric Flight Line Cart (HEF). This unique aircraft power supply can accommodate multiple different aircraft on the flight line or in a hanger such as the C-17 aircraft shown here. The unit is a battery charger combined with multiple power supplies to make the unit compatible with various types of aircraft. The integral lithium ion batteries can be charged by hangar power or by a diesel generator, which would permit operation in more remote areas. The new technology is an overall greener option for aircraft maintenance.
