What must all aircraft manufactured after March 1, 1979 possess?

All aircraft manufactured after March 1, 1979, are required to possess an Approved Flight Manual. The Approved Flight Manual provides critical information needed for safe operation of the aircraft, including limitations, performance data, and operating procedures specific to that aircraft model. This manual is essential for both pilots and maintenance personnel as it outlines the manufacturer's recommendations for the safe operation of the aircraft.

While the Type Certificate Data Sheet, Manufacturer's maintenance manual, and Airworthiness Certificate are all important documents related to aircraft operation and safety, the specific requirement for an Approved Flight Manual stems from regulatory standards implemented to ensure that pilots have access to vital operational information that has been evaluated and approved by aviation authorities. The presence of this manual enhances operational safety by guiding pilots in the correct use of aircraft systems and performance characteristics.
