Definition
A written record used during instruction or evaluation to list items where a student's performance, knowledge, or aircraft condition did not meet the required standard. The sheet identifies each shortfall so it can be reviewed, corrected, and signed off before training continues.
Plain English
A list of things that were wrong, missing, or below standard, written down so they can be fixed and checked off later.
Context Anchor
You may see a discrepancy sheet during aircraft inspection, maintenance follow-up, flight training review, or any evaluation where problems must be written down and corrected.
Derivation
Discrepancy comes from the Latin discrepare, meaning 'to differ' or 'to disagree.' A discrepancy sheet is literally a sheet listing the differences between what was expected and what was actually observed.
Why Pilots Care
Every open item must be resolved or deferred per regulations before the aircraft can be considered airworthy for the next flight.
Intuition Check
Do not read discrepancy sheet as just a casual complaint list. In aviation, it is a formal record of items that do not meet the required condition or standard and need action.
Example Sentence 1
After the lesson, the instructor wrote three items on the discrepancy sheet for the student to review before the next flight.
Example Sentence 2
The mechanic signed off each item on the discrepancy sheet once the repairs were completed and inspected.
