Which document is produced by the constructor of the aircraft?

The flight manual, also known as the Pilot’s Operating Handbook (POH) or Aircraft Flight Manual (AFM), is produced by the constructor of the aircraft. This document contains essential information regarding the operation of the aircraft, including performance data, operating limitations, and recommended procedures. It is tailored specifically for each aircraft model and provides pilots with vital information needed to safely operate and manage the aircraft under various conditions.

The constructor or manufacturer ensures that this manual reflects the unique characteristics and operational specifications of the aircraft, which is crucial for flight safety. The flight manual is a critical resource during both pre-flight planning and in-flight operations, helping pilots make informed decisions.

In contrast, the technical log generally records the operational history and maintenance performed on the aircraft; the release for service is typically associated with ensuring an aircraft is airworthy after maintenance; and the maintenance manual contains instructions and procedures for maintaining the aircraft, but is created for use by maintenance personnel rather than pilots. Thus, while these other documents play important roles in aircraft operation and maintenance, they are not produced by the constructor as an operational guide for pilots like the flight manual is.
