The maximum weight of an aircraft is the empty weight plus which components?

• A. empty weight plus crew, maximum fuel, cargo, and baggage
• B. empty weight plus crew, pax, and fixed equipment
• C. empty weight plus useful load
• D. empty weight plus payload and baggage

Answer: (C)

The main idea is that the maximum takeoff weight of an aircraft is found by adding the empty weight to the useful load. The useful load is everything that can be carried beyond the empty airframe: crew, passengers, baggage, cargo, and usable fuel. In other words, empty weight plus useful load gives the total allowable weight the aircraft can have at takeoff.

This is why the correct choice is the one that uses empty weight plus useful load. Useful load specifically includes all items that contribute to mission capability (people, baggage, cargo) and the fuel needed to fly, whereas the other options mix in elements differently or omit fuel, or treat components in a way that doesn’t align with how maximum weight is defined. Payload is often used to refer to passengers and cargo, excluding fuel, so using payload and baggage alone wouldn’t capture the full allowable load.
