Definition
The mental system that temporarily holds and actively works with a small amount of information for a short period — typically seconds to a minute — while a person is using it to think, decide, or act. It has limited capacity and information fades quickly unless rehearsed or transferred into long-term memory.
Plain English
It's the mental scratchpad you use to hold information just long enough to do something with it — like remembering a clearance until you've read it back, or holding a frequency in your head while you tune the radio.
Context Anchor
Seen in aviation instructor discussions about learning, cockpit workload, and why students can become overloaded during training.
Derivation
Working' points to the active use of the information — you're doing something with it right now. 'Short-term' points to how briefly it stays available. Together they describe memory that is in use and on a timer.
Why Pilots Care
Effective use prevents loss of critical temporary data like headings or altitudes, reducing errors during high-workload phases of flight.
Analogy
Think of it like a small desk. You can spread out a few papers and work with them, but if someone keeps handing you more, the older ones get pushed off the edge.
Grounding Statement
When a student hears several instructions at once, working or short-term memory is the part of the mind trying to hold those instructions long enough to carry them out.
Intuition Check
Working or short-term memory does not mean weak memory or lack of intelligence. It means the normal, limited mental space every person uses for information needed right now.
Example Sentence 1
The instructor kept the briefing short because long instructions overwhelm a student's working memory.
Example Sentence 2
During the approach briefing, short-term memory allowed recall of the next heading change without looking at notes.
