Plain English Meaning
A list of things that were wrong, missing, or below standard, written down so they can be fixed and checked off later.
Full 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.
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.
