What does the acronym 'GUMPS' represent in landing checks?

The acronym 'GUMPS' is a mnemonic used during landing checks to help pilots remember key items to verify before landing. In this context, the correct representation includes critical components necessary for a safe landing. 'G' stands for Gear, which is crucial to ensure the aircraft is configured properly for landing. 'U' represents Undercarriage, which reinforces the need to check the landing gear status, ensuring it is down and locked. 'M' denotes Mixture, reminding pilots to adjust the fuel-air mixture for optimal engine performance during landing. 'P' signifies Propeller, ensuring that the propeller is in the correct configuration, typically in a 'low pitch' or 'high RPM' setting for landing. Lastly, 'S' stands for Seatbelts, emphasizing the importance of ensuring that passengers and crew are secure for the landing phase.

The other options do not accurately represent the standard 'GUMPS' checklist utilized in aviation, missing key components essential for safe operations during landing.
