1. Give the distance of the CG from the datum for an aircraft where the CG is 23% MAC. The MAC is 90 inches and LEMAC is located 321 inches aft of the datum.
2. 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)
3. An operator has a fleet of 43 aircraft, how many aircraft must be weighed at the same time to maintain the fleet value?
4. The mass and balance information gives: Basic Mass: 1.200 kg Basic Balance Arm: 3 m Under these conditions the Basic centre of gravity is at 25% of the Mean Aerodynamic Chord (MAC). The length of MAC is 2 m. In the mass and balance section of the flight manual the following information is given: Position Arm front seats: 2,5 m Position Arm rear seats: 3,5 m Position-Arm rear hold: 4,5 m Position Arm fuel tanks: 3,0 m The pilot and one passenger embark; each weighs 80 kg. Fuel tanks contain 140 litres of petrol with a density of 0,714. The rear seats are not occupied. Taxi fuel is negligible. The position of the centre of gravity at takeoff (as % MAC) is:
5. An aircraft is weighed and the following recordings are made:
Nose wheel assembly scale: 5.330 kg
Left main wheel assembly scale: 12.370 kg
Right main wheel assembly scale: 12.480 kg
If the operational items amount to a mass of 1.780 kg with a crew mass of 545 kg, the Empty Mass, as entered in the weight schedule, is:
