Plain English Meaning
A simple word, phrase, or rhyme that helps a pilot remember a list of things to do or check, especially when there isn't time to pull out the printed checklist.
Full Definition
A short, easy-to-recall device — typically an acronym, mnemonic, or rhyme — used by pilots to reliably recall a sequence of items, checks, or actions without referring to a written reference. Memory aids are commonly used for time-critical procedures, simple flow checks, and items that must be performed from memory before a written checklist is consulted.
Context Anchor
Seen in cockpit checklist use, especially when pilots use flows or short reminders before verifying items with a checklist.
Derivation
Memory comes from the Latin word memoria, meaning remembrance. Aid comes from words meaning to help. Together, the phrase means something that helps you remember.
Why Pilots Care
A good memory aid reduces the chance of skipping a critical step that could affect safety.
Intuition Check
A memory aid is not the same as a checklist. It is only a reminder; it does not prove that every required item has been completed.
Example Sentence 1
Many pilots use the memory aid GUMPS — Gas, Undercarriage, Mixture, Propeller, Switches — as a final check before landing.
Example Sentence 2
Checklists serve as the main memory aid during both preflight and in-flight emergencies.
