BUMPH is an acronym for

• Brakes - unlocked so that wheels are free to rotate on touchdown
• Undercarriage - down and locked (or welded in the case of fixed-gear aircraft)
• Mixture - set full rich (or as appropriate to temperature and altitude)
• Propellor - set full fine pitch (when a variable pitch propellor is fitted)
• Hatches (and Harnesses) - secured.

These provide only the bare minimum of pre-landing checks, but a more complete list doesn't provide a neat acronym. In this sense the mnemonic should probably be used only as a reminder rather than a complete set of checks.

• Mixture
• Carb heat - apply and check for icing (This step is omitted in aircraft with fuel injection systems)
• Fuel - select correct tank and check there's enough to perform a go around if necessary
• Flaps - select landing or descending flap
• Hatches and Harness
• Transponder - select as appropriate
• Landing Light - switch on
