Definition
Ground support equipment (GSE) is the collective term for the vehicles, machinery, and tools used on the ground to service an aircraft between flights or during maintenance. This includes items such as tugs and tow bars for moving the aircraft, ground power units for supplying electrical power, air start units, fuel trucks, baggage carts, belt loaders, lavatory and water service trucks, deicing rigs, and passenger boarding stairs.
Plain English
All the gear on the ramp that gets used on an aircraft when it isn't flying — anything that pushes it, powers it, fuels it, loads it, or services it.
Context Anchor
Seen in airport ramp operations, preflight planning, aircraft servicing, maintenance, and ground handling discussions.
Why Pilots Care
Pilots interact with GSE during every turnaround — calling for a tug, requesting external power, ordering fuel, or coordinating deicing. Knowing what's available (and what isn't) at a given airport affects flight planning, especially at smaller fields where some equipment may not be on hand.
Intuition Check
Do not read “ground support” as general help from people on the ground. In this aviation use, it means the physical equipment used to service or handle an aircraft while it is not flying.
Example Sentence 1
The captain called the ramp to request GSE for an external power start because the aircraft battery was low.
Example Sentence 2
Before pushback, the pilot confirmed that all GSE had been cleared from the vicinity of the airplane.
