1. 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:
2. What is the Balance Arm, the maximum compartment load and the running load for the most aft compartment of the fwd cargo hold?
3. From the manual for the single engine piston/propeller
aeroplane, the maximum floor loading is:
4. At a given mass the CG position is at 15% MAC. If the leading edge of MAC is at a position 625,6 inches aft of the datum and the MAC is given as 134,5 inches determine the position of the CG in relation to the datum:
5. Using the data for the MRJT, what is the Maximum Compartment Load for the area between BA 286 and 343:
