1. Without the crew, the weight and the CG position of the aircraft are 7.000 kg and 4,70 m. The mass of the pilot is 90 kg The mass of the copilot is 75 kg The mass of the flight engineer is 90 kg With this crew on board, the CG position of the aircraft will be:
2. A turbojet aeroplane is parked with the following data:
Corrected Dry Operating Mass: 110.100 kg
Basic corrected index: 118,6
Initial cargo distribution:
Cargo 1: 4.000 kg
Cargo 2: 2.000 kg
Cargo 3: 2.000 kg
Other cargo compartments are empty
Takeoff Mass: 200.000 kg
Centre of gravity (CG) location: 32%
For performance reasons, the captain decides to redistribute part of the cargo loading between cargo compartments, in order to takeoff with a new CG location of 34%. He asks for a transfer of:

With respect to multi-engine piston powered aeroplane, determine the Block Fuel moment (Ibs.in) in the following conditions: Basic Empty Mass: 3.210 lbs Basic arm: 88,5 In One pilot: 160 lbs Front seat passenger: 200 lbs Centre seat passengers: 290 lbs (total) One passenger rear seat: 110 lbs Baggage in zone 1: 100 lbs Baggage in zone 4: 50 lbs Block Fuel: 100 US Gal Trip Fuel: 55 US Gal Fuel for start up and taxi (included in Block Fuel): 3 US Gal Fuel density: 6 lbs/US Gal
4. Without the crew, the mass and longitudinal CG position of the aircraft are 6.000 kg and 4,70 m. The mass of the pilot: 90 kg The mass of the copilot: 100 kg The mass of the flight engineer: 80 kg With the crew, the mass and longitudinal CG position of the aircraft are:
5. From the data given at the appendix and assuming a fuel index shift of – 5,7 from the ZFM loaded index, determine which of the following, is the correct value (percentage MAC) for the position of the centre of gravity at Takeoff Mass:
