What is the maximum zero fuel weight (MZFW) of the aircraft?

The maximum zero fuel weight (MZFW) of an aircraft is a critical limitation that refers to the maximum weight of the aircraft without any usable fuel. This weight includes the aircraft's structure, payload (which encompasses passengers, cargo, and baggage), and any other fixed items on board, excluding the weight of the fuel.

In this scenario, the selection of 69,800 lbs as the MZFW means that this figure reflects regulatory and performance considerations established by the aircraft manufacturer and regulatory authorities. It is essential for flight operations, load planning, and ensuring safety during flight operations. If the aircraft exceeds this weight, it may not be able to perform as expected during takeoff, flight, or landing phases due to altered flight characteristics.

The other options likely represent figures that exceed the MZFW limit, indicating that they would not be suitable for operational use when considering maximum safety and performance for the aircraft. Understanding MZFW is crucial for ensuring compliance with the aircraft's design parameters and operational regulations.
