Случайные 5 вопросов:
1. The planned Takeoff Mass of a turbojet aeroplane is 180.000 kg, with its centre of gravity located at 26% MAC (Mean Aerodynamic Cord). Shortly prior to engine start, the local staff informs the flight crew that 4.000 kg must be unloaded from cargo 4. After the handling operation, the new centre of gravity location in % MAC will be:

2. The Total Mass of an aeroplane is 145.000 kg and the centre of gravity limits are between 4,7 m and 6,9 m aft of the datum. The loaded centre of gravity position is 4,4 m aft. How much mass must be transferred from the front to the rear hold in order to bring the out of limit centre of gravity position to the foremost limit?

3. The mass of an aeroplane is 1.950 kg. If 450 kg is added to a cargo hold 1,75 metres from the loaded centre of gravity (CG). The loaded CG will move:
4. With respect to a multi-engine piston powered aeroplane, determine the CG location at takeoff 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 Zero Fuel Mass: 4.120 lbs Moment at Zero Fuel Mass: 377.751 Ibs.in 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


5. Given that the Total Mass of an aeroplane is 112.000 kg with a centre of gravity position at 22,62 m aft of the datum. The centre of gravity limits are between 18 m and 22 m. How much mass must be removed from the rear hold (30 m aft of the datum) to move the centre of gravity to the middle of the limits:
