prescribed in FAA technical specifications, the maximum zero fuel 
weight, less empty weight, less all justifiable airplane equipment, and 
less the operating load (consisting of minimum flightcrew, foods and 
beverages and supplies and equipment related to foods and beverages, but 
not including disposable fuel or oil):
    (2) For all other airplanes, the maximum certificated takeoff weight 
of an airplane, less the empty weight, less all justifiable airplane 
equipment, and less the operating load (consisting of minimum fuel load, 
oil, and flightcrew). The allowance for the weight of the crew, oil, and 
fuel is as follows:
    (i) Crew--200 pounds for each crewmember required under this chapter
    (ii) Oil--350 pounds.
    (iii) Fuel--the minimum weight of fuel required under this chapter

weather conditions that does not involve extended overwater operations.
    (b) For the purposes of this part, empty weight means the weight of 
the airframe, engines, propellers, and fixed equipment. Empty weight 
excludes the weight of the crew and payload, but includes the weight of 
all fixed ballast, unusable fuel supply, undrainable oil, total quantity 
of engine coolant, and total quantity of hydraulic fluid.
    (c) For the purposes of this part, maximum zero fuel weight means 
the maximum permissible weight of an airplane with no disposable fuel or

means any equipment necessary for the operation of the airplane. It does 
not include equipment or ballast specifically installed, permanently or 
otherwise, for the purpose of altering the empty weight of an airplane 
to meet the maximum payload capacity.
