What does the abbreviation "AFM" stand for in aviation maintenance?

The abbreviation "AFM" stands for Aircraft Flight Manual. This document is crucial in aviation maintenance and operation as it provides essential information regarding the performance, operation, and limitations of the aircraft. The AFM is tailored specifically to each aircraft model and includes operating procedures, performance data, and emergency information that pilots and maintenance personnel must be familiar with to ensure safe operation.

In contrast, options like "Aerodynamic Flight Manual" and "Aviation Functional Manual" do not represent standard or recognized documents in aviation. While "Aircraft Fuel Management" refers to the management of fuel systems and efficiency in aircraft operations, it is not the correct abbreviation for AFM. Therefore, understanding that the AFM serves as a comprehensive guide for aircraft operation makes it clear why this answer is indeed the correct one.
