Step-by-step explanation:
The basic weight of an aircraft, as determined in accordance with the aircraft flight manual (AFM), refers to the weight of the aircraft without any additional equipment, passengers, or cargo. It includes the weight of the airframe, engines, fuel, and other necessary systems. The AFM provides specific weight limits and loading instructions for safe and efficient operation of the aircraft.
For example, the basic weight of a Boeing 777-200ER airliner is specified in the AFM and is used as a reference for calculating various performance parameters, such as takeoff weight, fuel consumption, and range.
