Definition
The manufacturer-published document that provides approved operating procedures, performance data, limitations, and emergency procedures for a specific aircraft. It is the authoritative reference for how that aircraft is to be flown and serves as the basis for required operating handbooks such as the Pilot's Operating Handbook (POH) or Aircraft Flight Manual (AFM).
Plain English
The book from the aircraft's maker that tells the pilot how to operate that specific aircraft, including normal procedures, limits, and what to do in an emergency.
Context Anchor
In this chapter, a pilot may refer to the aircraft operator's manual for the aircraft-specific actions recommended during an inadvertent thunderstorm encounter or other rough-air situation.
Derivation
Manual comes from a Latin word meaning “hand,” and came to mean a small book kept at hand for practical use. Operator means the person or organization that operates the aircraft. Together, the phrase points to the practical operating book for the aircraft, not a general aviation textbook.
Why Pilots Care
Pilots are required to operate within the limitations and procedures stated in this manual; deviation can affect airworthiness and legal compliance.
Intuition Check
Do not read this as just any helpful book about airplanes. In this context, it means the official operating manual for the specific aircraft being flown or operated.
Example Sentence 1
Before flying an unfamiliar aircraft, the pilot reviewed the aircraft operator's manual to learn its airspeed limits and emergency procedures.
Example Sentence 2
According to the aircraft operator's manual, maximum crosswind component for this model is 15 knots.
