Definition
FAA-issued add-on qualifications to a pilot certificate that authorize the holder to operate an aircraft under Instrument Flight Rules (IFR) and in weather conditions below those required for visual flight. Issued by aircraft category — Instrument Airplane, Instrument Helicopter, and Instrument Powered-Lift — each requires meeting specific aeronautical experience, knowledge test, and practical test standards under 14 CFR Part 61.
Plain English
Extra qualifications added to a pilot's license that allow them to fly using only the cockpit instruments — for example, in clouds or low visibility — instead of needing to see outside.
Context Anchor
Seen in training plans, course outlines, and FAA discussions of how pilots progress from basic visual flying to more advanced flight training.
Derivation
"Instrument" here refers to the cockpit instruments a pilot relies on when outside visual references are unavailable. A "rating" is a formal authorization added to a pilot certificate that expands what the pilot is allowed to do. So an instrument rating is permission to fly by instruments.
Why Pilots Care
It enables safe flight in clouds, low visibility, and at night, expanding operational capability and supporting career progression.
Intuition Check
A rating is not a review, grade, or performance score here. It is an official FAA approval that adds a specific flying privilege to a pilot certificate.
Example Sentence 1
After earning her private pilot certificate, she began training for her instrument rating so she could fly through cloud layers safely and legally.
Example Sentence 2
The instrument rating requires both ground school and a minimum number of hours flown under simulated instrument conditions.
