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.
Plain English
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.
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.
