Aircraft ground handling

In aviation, aircraft ground handling defines the servicing of an aircraft while it is on the ground and (usually) parked at a terminal gate of an airport. In aviation, aircraft ground handling defines the servicing of an aircraft while it is on the ground and (usually) parked at a terminal gate of an airport. Many airlines subcontract ground handling to airports, handling agents or even to another airline. According to the International Air Transport Association (IATA), conservative estimates indicate airlines outsource more than 50 per cent of the ground handling that takes place at the world's airports. Ground handling addresses the many service requirements of an airliner between the time it arrives at a terminal gate and the time it departs on its next flight. Speed, efficiency, and accuracy are important in ground handling services in order to minimize the turnaround time (the time during which the aircraft must remain parked at the gate). Faster turnarounds for lower ground times are correlated to better profits. Airlines with less-frequent service or fewer resources at a particular location sometimes subcontract ground handling or on-call aircraft maintenance to another airline, as it is a short-term cheaper alternative to setting up its own ground handling or maintenance capabilities. Airlines may participate in an industry-standard Mutual Assistance Ground Service Agreement (MAGSA). The MAGSA is published by the Air Transport Association (the current version is from 1981) and is used by airlines to assess prices for maintenance and support to aircraft at so-called MAGSA Rates, which are updated annually based on changes in the U.S. Producer Price Index. Airlines may choose to contract for ground handling services under the terms of a Standard Ground Handling Agreement (SGHA) published in the International Air Transport Association (IATA) Airport Handling Manual. Airlines may also contract for ground handling services under non-standard terms.
