What is defined as Basic Empty Weight?

Basic Empty Weight is defined as the weight of the aircraft as it is configured for flight, minus any passengers or cargo. Specifically, it includes the airframe, engines, all fixed equipment, full oil, and unusable fuel. This measurement does not include the weight of any passengers or baggage, which are variable and change with different flight operations.

Understanding the proper definition of Basic Empty Weight is crucial for pilots during flight planning, as it allows them to calculate the total weight of the aircraft when adding passengers and cargo, ensuring compliance with safety limits and performance calculations. This weight serves as a baseline from which all other weights are considered, including maximum takeoff weight and loaded weight.
