Definition
The mental ability to remember to perform a planned action at a future moment or in response to a future cue. In aviation human factors, prospective memory is the cognitive function that allows a pilot to recall a deferred task — such as resetting an altimeter, switching fuel tanks, or making a position report — when the appropriate time, location, or trigger occurs.
Plain English
Remembering to do something later. It is the kind of memory that fires when the right moment arrives, like remembering to lower the gear on approach or to call ATC when crossing a fix.
Context Anchor
Seen in aviation human factors, cockpit task management, checklist use, and any situation where a pilot must remember a delayed action during flight.
Derivation
From Latin prospectus, meaning 'looking forward.' Prospective memory is literally memory that looks ahead — memory aimed at a future action rather than recall of past information.
Why Pilots Care
Supports reliable execution of time- or event-based actions such as fuel switches, position reports, and configuration changes.
Analogy
It is like telling yourself, “When I get home, I need to take the keys out of my bag.” The hard part is not knowing what to do; it is remembering to do it at the right moment.
Grounding Statement
If a pilot decides now to make a call at the next reporting point, prospective memory is what helps that action happen when the point is reached.
Intuition Check
Prospective memory is not memory of the past. It is memory for an action you intend to do in the future.
Example Sentence 1
After ATC instructed her to report passing 5,000 feet, the pilot relied on prospective memory to make the call — but a radio distraction caused her to miss it.
Example Sentence 2
Good prospective memory helped her call ATC for the approach clearance at the planned waypoint.
