# How do you calculate maximum zero fuel weight?How do you calculate maximum zero fuel weight?

The zero-fuel weight (ZFW) of an aircraft is the total weight of the airplane and all its contents, minus the total weight of the usable fuel on board. Unusable fuel is included in ZFW. For example, if an aircraft is flying at a weight of 5,000 kg and the weight of fuel on board is 500 kg, the ZFW is 4,500 kg.Click to see full answer. Also question is, what does Max Zero Fuel Weight mean?Zero Fuel Weight (ZFW) is the maximum permissible weight of an airplane with no disposable fuel or oil. In simple terms, zero fuel weight is the most an airplane can weigh when loaded with passengers and cargo with no usable fuel or oil onboard. does maximum takeoff weight include fuel? Basic operating weight accounts for all of the fluids necessary for the aircraft to operate including: oils, hydraulic fluid, coolant, water and fuel. Maximum takeoff weight is straightforward; it is simply the maximum weight a pilot can plan a takeoff due to aircraft limitations, structural or otherwise. Besides, why do some aircraft have a zero fuel weight limitation? A. To ensure c.g. remains in the normal range even if fuel starvation occurs in flight. To ensure all cabin doors will close after aircraft fueling due to fuselage bending stresses that occur during fueling operations.How is aircraft payload calculated? Divide the payload between people and cargo. Count the aircraft crew as people. If known, the actual weight should be used. If the actual weights of the crew are not known, estimate the weights as 174 lbs. Add the passenger weights. Count each male passenger as 174 lbs. (79.0 kg), each female passenger as 127 lbs.
