Refer to Annex -031-053.
The aircraft has initially 225 l of fuel in the tank. The pilot takes 200 kg of additional fuel. How is the Centre of Gravity affected?
  • A
    It is not affected.
  • B
    It moves towards the aft of the aircraft.
  • C
    It moves towards the nose of the aircraft.
  • D
    It moves towards the bottom of the aircraft.
In the attachment:
1- find the row representing 225 L and calculate the CG:
            - CG = moment / mass = 805416 / 180 = 4474 mm = 4.47 m aft of the datum
            (as CG is positive result so its aft of the datum)

2- find the row representing 380 kg (180 + 200) and calculate CG:
            - CG = 1590488 / 380 = 4185 mm = 4.18 m aft of the datum

New CG after adding 200 kg of fuel: move towards the nose of the aircraft.
