Aircraft ground crew

Dependent on the type of aircraft being operated, airline ground crew members typically include:
airframe The mechanical structure of an aircraft is known as the airframe. This structure is typically considered to include the fuselage, undercarriage, empennage and wings, and excludes the propulsion system. Airframe design is a field of aerospa ...

Non-powered flight

Ground crew required for non-powered flight, such as gliders will include people who manually handle the glider aircraft from their storage location (such as an
aircraft hangar A hangar is a building or structure designed to hold aircraft or spacecraft. Hangars are built of metal, wood, or concrete. The word ''hangar'' comes from Middle French ''hanghart'' ("enclosure near a house"), of Germanic origin, from Frankish ...
) to their respective launch site, and then to return them at the end of flying. Aero-towed launched gliders will require ground crew commensurate with supporting the tow aircraft, which are typically single piston-engined

(GA) small lightweight utility variants, often Cessna. For winch-launched gliders, ground crew will also include the winch-launch operator(s), and also a pay-out vehicle operator whose purpose is to draw or pay-out the winch launch cables (usually two cables per launch vehicle) which will be located at the far end of the upwind side of the airfield, to the gliders awaiting their turn to launch at the opposite end of the airfield.


Non-controlled flight

For those aircraft that do not possess any controls for changing the direction course of the aircraft, commonly known as
hot-air balloon A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule), which carries p ...
s, these require particularly unique ground crew. Their roles include preparing the passenger basket (or gondola) with the correct amount of pressurized gas for the burners, testing of the burners, calculating the total mass of the

pilot and all passengers, calculating and applying appropriate ballast weight (fixed internal and releasable external). Then the assembly of the passenger basket to its lift balloon envelope, laying out the balloon envelope fabric in a manner that facilitates efficient inflation. Prior to launch, it will require personnel to 'waft' the balloon envelope during horizontal burner operation to ensure an efficient fill. When the balloon envelope it itself airborne (but still not able to lift the basket with its pilot and any passengers), the ground crew will be required to hold ground tug ropes, to maintain the correct position of the balloon over the now vertically firing burner, and to prevent the basket from being uncontrollably dragged along the ground, until the balloon is totally full and capable of launch. Once in flight, the hot air balloon ground crew undertakes a new task, that of driving one or more ' chase vehicles', initially to follow the progress and trajectory of the balloon in flight as best it can. Most hot air balloons have zero aviation-specific navigation aids, though modern pilots will typically utilize satellite navigation features found on many

s, along with the mobile voice telephony to maintain contact with the chase vehicle. The final task of the chase vehicle will be to locate and attend the balloon landing site, to repatriate any passengers back to their respective location, and also to thoroughly deflate the balloon envelope, then correctly fold and stow away the envelope, along with the basket, and deliver all balloon equipment and its pilot back to their preferred location.

This is absolutely critical to safe airport operations, as it the major process used to prevent

On military facilities, ground crew members are tasked with daily FOD walks, or 'FOD plods', whereby a team of people will fan out in a line across the entire width of the runway, and walk the length of the entire active runway, to visually inspect the runway surface, and its immediate environs, to look for and removes any items or 'foreign objects' found; this is typically done in the morning, prior to the first despatch of an aircraft for that day. Virtually all airports which cater for large aircraft will have a fleet of
