Definition
A grading category used by an instructor on a Single-Pilot Resource Management (SRM) assessment to indicate that a particular skill or behavior could not be evaluated during the lesson because the situation requiring it did not arise.
Plain English
The instructor didn't see the student do this skill — not because the student failed, but because nothing happened during the flight that called for it.
Context Anchor
Seen on instructor assessment forms, especially when evaluating single-pilot resource management skills during flight or ground scenarios.
Why Pilots Care
It distinguishes between skills requiring improvement and those that simply were not demonstrated, avoiding incorrect assumptions about performance.
Intuition Check
Do not read Not Observed as meaning the student did something wrong. It means the instructor did not see enough evidence to rate that item.
Example Sentence 1
Because the weather stayed clear and stable, the instructor marked diversion decision-making as Not Observed on the assessment.
Example Sentence 2
Several SRM behaviors received a Not Observed rating on the stage check due to the short duration of the flight.
