Where can one find the basic empty weight and limitations of an aircraft?

The correct choice is the Aircraft Flight Manual (AFM). The AFM is a crucial document that contains a wealth of information about an aircraft's performance, operating limitations, and essential data required for safe operation. Within the AFM, you will find detailed specifications, including the basic empty weight of the aircraft, which is the weight of the aircraft without payload or fuel. Additionally, it outlines limitations related to weight and balance, as well as operating procedures, which are vital for the pilot to follow.

While the Pilot's Manual may provide instructional guidance for flying and operating the aircraft, it does not typically serve as the authoritative source of the specific weight and limitations data. The Aircraft Registry is primarily a record-keeping system used by regulatory authorities and does not include detailed operational specifications for individual aircraft. Manufacturer's Specifications can provide technical data, but they may not aggregate all necessary information specific to an aircraft's operational limits in one comprehensive format like the AFM does. Thus, the Aircraft Flight Manual is the definitive resource for this type of critical information.
