1 - The loaded centre of gravity (cg) of an aeroplane is 713 mm aft of datum. The mean aerodynamic chord lies between station 524 mm aft and 1706 mm aft. The cg expressed as% MAC (mean aerodynamic chord) is:
60 %
41 %
10 %
16 %
2 - 'Standard Mass' as used in the computation of passenger load establish the mass of a child as
35 kg only if they are over 2 years old and occupy a seat.
35 kg irrespective of age provided they occupy a seat.
35 kg for children over 2 years occupying a seat and 10 kg for infants (less than 2 years) occupying a seat.
35 kg for children over 2 years occupying a seat and 10 kg for infants (less than 2 years) not occupying a seat.
3 - What determines the longitudinal stability of an aeroplane ?
The effectiveness of the horizontal stabilizer, rudder and rudder trim tab.
The location of the centre of gravity with respect to the neutral point.
The dihedral, angle of sweepback and the keel effect.
The relationship of thrust and lift to weight and drag.
4 - If the centre of gravity is near the forward limit the aeroplane will:
Benefit from reduced drag due to the decrease in angle of attack.
Require less power for a given airspeed.
Require elevator trim which will result in an increase in fuel consumption.
Tend to over rotate during take-off.
5 - An aircraft basic empty mass is 3000 kg.The maximum take-off, landing, and zero-fuel mass are identical, at 5200 kg. Ramp fuel is 650 kg, the taxi fuel is 50 kg.The maximum traffic load is:
1 550 kg
2 200 kg
1 600 kg
2 150 kg
6 - Allowed traffic load is the difference between:
Allowed take off mass and basic empty mass.
Allowed take off mass and basic empty mass plus trip fuel.
Operating mass and basic empty mass.
Allowed take off mass and operating mass.
7 - Given are the following information at take-off____________________________________________________________ STATION....................MASS (kg)....ARM (cm)....MOMENT (kgcm)____________________________________________________________ Basic Empty Condition...12045.........+30......+361350Crew..................................145........-160.......-23200Freight ( 1)..........................570.......+200......+114000Freight ( 2)..........................410..........-40.......-16400Fuel.................................6045...........-8.......-48360Given that the flight time is 2 h and the estimated fuel flow will be 1050 litres per h. The specific density of fuel is 0.79. The 'Freight ( 2)' will be dropped during flight within the scope of a rescue action.Calculate the CG position at landing.
25 cm aft of datum
24.3 cm aft of datum
23.7 cm aft of datum
22 cm aft of datum
8 - The operator of an aircraft equipped with 50 seats uses standard masses for passengers and baggage. During the preparation of a scheduled flight a group of passengers present themselves at the check-in desk, it is apparent that even the lightest of these exceeds the value of the declared standard mass.
The operator may use the standard masses for the load and balance calculation without correction
The operator may use the standard masses for the balance but must correct these for the load calculation
The operator should use the individual masses of the passengers or alter the standard mass
The operator is obliged to use the actual masses of each passenger
9 - . What effect has a centre of gravity close to the most forward limit?
A better rate of climb capability.
A reduction in the specific fuel consumption.
A reduced rate of climb capability.
A decreased induced drag.
10 - The term 'useful load' as applied to an aircraft includes
Traffic load plus usable fuel.
The revenue-earning portion of traffic load plus useable fuel.
The revenue-earning portion of traffic load only.
Traffic load only.
