gump
n. countablen. a checklist pilots use before landing to make sure the plane is ready. It helps you remember to check the wheels, the fuel, and the engine settings.
n. a mnemonic acronym used by pilots during the pre-landing phase to ensure critical aircraft configurations are set. Each letter represents a specific check: Gas, Undercarriage, Mixture, and Propeller.
The pilot performed his GUMP check before entering the final approach.
Even experienced pilots rely on the GUMP mnemonic to prevent gear-up landings during busy traffic patterns.
While modern glass cockpits provide automated alerts, many flight instructors still insist that students verbalize the GUMP sequence to build a disciplined habit of manual verification before touchdown.
Perhaps related to gumption. The term long pre-dates the slow-witted character from the 1994 film Forrest Gump.
Often used as a modifier before 'check' or 'routine'; frequently written in all caps as it is an acronym.
