GUMPS

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]

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

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]
