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]
