What is ramp weight?

Ramp weight refers to the total weight of an aircraft just prior to departure, including the weight of the aircraft itself, the passengers, cargo, and fuel that is usable for the flight.

The correct answer is determined based on the components of ramp weight, which can effectively be defined as the zero fuel weight, which accounts for the aircraft and its contents excluding fuel, plus the usable fuel weight. This definition captures everything necessary for flight, such as passengers and cargo, alongside the fuel that can be consumed during the flight. It’s important for operational planning and ensuring that the aircraft remains within its weight limitations for safe takeoff and flight.

Utilizing the other options helps clarify why they do not define ramp weight accurately. For instance, zero fuel weight plus unusable fuel weight would not accurately represent the operational weight of the aircraft since unusable fuel does not contribute to the aircraft's ability to perform flight operations. The other options also misrepresent ramp weight by either including incorrect components or focusing on aspects unrelated to the total weight necessary for departure.
