What does the total weight of an aircraft consist of?

The total weight of an aircraft includes the empty weight plus the useful load. Empty weight refers to the weight of the aircraft without any payload or fuel, essentially encompassing the airframe, systems, and all required operating components that are permanently installed. Useful load represents the additional weight the aircraft can carry, which includes passengers, cargo, and usable fuel.

By combining these two components, you arrive at the total weight of the aircraft, which is crucial for ensuring the aircraft operates within its weight limits for safe flying. Understanding this relationship is vital for pilots and maintenance professionals when preparing for flight operations, as exceeding weight limits can affect performance and safety during flight.
