GUMPS

This article is about an aviation mnemonic. For the San Francisco retailer, see Gump's.

GUMPS is an acronym widely used by retractable gear aircraft pilots as a mental checklist to ensure nothing critical has been forgotten before landing. Its popularity is widespread, appearing in flight student curricula, FAA publications and aviation magazines.^[1][2][3]

Due to distraction and preoccupation during the landing sequence approximately 100 gear-up landing incidents occurred each year in the United States between 1998 and 2003.^[4]

The checklist

GUMPS stands for:^[5][6]

• G – Gas (Fuel on the proper tank, fuel pump on as required, positive fuel pressure)
• U – Undercarriage (landing gear down)
• M – Mixture (fuel mixture set)
• P – Propeller (prop set)
• S – Seat belts and Switches (lights, pitot heat, etc.) ^[7]
