Jettison (aviation)
In aviation, to jettison is to discard fuel, external stores or other expendable items.[1][2] The item is usually jettisoned by operating a switch or handle; external stores may be separated from the aircraft by use of explosive bolts or a mechanism.
Fuel jettison
- Fuel jettisoning or fuel dumping is an emergency procedure used by crews to reduce the weight of an aircraft in an emergency when the aircraft has reached its maximum landing weight.[2]
External stores jettison
- Some military aircraft can carry weapons (for example bombs or rockets) and fuel tanks on external hardpoints. The pilot can jettison them if necessary, so they do not inhibit actions during combat or in an emergency. Airports may establish specific safe areas for the jettison of external stores, when required.[3][4]

Other
- Some aircraft may jettison components for various other reasons, for example slip-wing aircraft such as the Hillson F.H.40 that discards the upper wing after take off.[5][6]
