GUMPS is a slang term commonly used in aviation, primarily by pilots, to refer to a pre-flight checklist used before takeoff. The acronym GUMPS stands for "Gas, Undercarriage, Mixture, Prop, and Switches." Each letter represents a crucial element or system that needs to be checked before initiating flight.
The first element, "Gas," requires the pilot to ensure that there is an adequate amount of fuel in the aircraft's tanks. This step involves verifying fuel quantities and selecting the appropriate tank for flight. "Undercarriage" refers to the landing gear, which needs to be visually inspected, ensuring that it is properly extended or retracted depending on the phase of flight.
"Mixture" refers to the fuel-to-air ratio being adjusted properly for optimal engine performance. The pilot verifies that the mixture control is set according to the manufacturer's recommendations. "Prop" refers to the propeller system, which requires the pilot to check its condition, balance, and secure attachment to the engine. Last but not least, "Switches" involves ensuring that all necessary switches, such as avionics, lights, and other equipment are in the desired position before takeoff.
By adhering to the GUMPS checklist, pilots aim to optimize their safety and minimize the likelihood of errors or malfunctions during flight. It serves as a reminder to pay attention to essential pre-flight procedures, ultimately ensuring a greater level of preparedness for takeoff.
