Practise Mass and Balance
The Maximum Zero Fuel Mass is the mass of the aeroplane with no usable fuel on board. It is a limitation which is:
The Zero Fuel Mass and the Dry Operating Mass
Under EASA guidance, passenger mass may be established from a verbal statement by or on behalf of each passenger, with the prescribed allowances for clothing and hand baggage, when the number of passenger seats available in an aeroplane is:
The Maximum Zero Fuel Mass is a structural limiting mass. It is made up of the aeroplane Dry Operational mass plus
The maximum quantity of fuel that can be loaded into an aircraft's tanks is given as 3800 US Gallons. If the fuel density (specific gravity) is given as 0.79 the mass of fuel which may be loaded is:
Conversion of fuel volume to mass
According to the mass terminology used in CAA CAP 696, the term 'useful load' includes:
For the medium range transport aeroplane, from the loading manual, determine the maximum total volume of fuel which can be loaded into the main wing tanks. (Fuel density value 0.78)
The operator of an aircraft equipped with 50 seats uses standard masses for passengers and baggage. During the preparation of a scheduled flight a group of passengers present themselves at the check-in desk, it is apparent that even the lightest of these exceeds the value of the declared standard mass.
By adding to the basic empty mass the following fixed necessary equipment for a specific flight (catering, safety and rescue equipment, fly away kit, crew), we get:
