Ground support equipment (GSE) are designed to support the operations of an aircraft whilst it is at the airport. GSE comprises airplane push-back & hook-up, forklifts & lifts, carts, vehicles, air-conditioning tugs, belt & container loaders, light-duty trucks, and other equipment that serve the purpose of powering, towing, and servicing. Further, such equipment enable passenger handling, baggage handling, aircraft mobility, repair, service, and maintenance functions. Many of the airlines either own/ maintain the GSE or possess full service leasing from the equipment management companies.
