A document, typically in Portable Document Format (PDF), is used to calculate and record the distribution of an aircraft’s mass and whether it falls within acceptable limits. This document accounts for the mass and location of all items onboard, including the aircraft itself, crew, passengers, fuel, and cargo. An example would be a pilot preparing this document before a flight to ensure that the aircraft’s center of gravity is within the specified range.
Adherence to these calculations is crucial for maintaining stability and control during flight. Proper distribution of mass optimizes performance, reduces stress on the airframe, and enhances safety. Historically, inaccurate calculations have been a contributing factor in aviation accidents, emphasizing the importance of meticulous and accurate documentation.
