Question 1

The crew of a transport aeroplane prepares a flight using the following data:- Dry operating mass: 90 000 kg- Block fuel: 30 000 kg- Taxi fuel: 800 kg- Maximum take-off mass: 145 000 kg The traffic load available for this flight is:

Accepted Answer

25 800 kg

Answer

55 000 kg

Answer

25 000 kg

Answer

55 800 kg

Question 2

Traffic Load is the:

Accepted Answer

Zero Fuel Mass minus Dry Operating Mass.

Answer

Dry Operating Mass minus the disposable load.

Answer

Take-off Mass minus Zero Fuel Mass.

Answer

Dry Operating Mass minus the Variable Load.

Question 3

Given:Maximum structural take-off mass= 146 900 kg Maximum structural landing mass= 93 800 kg Maximum zero fuel mass= 86 400 kg. Trip fuel= 27 500 kg. Block fuel= 35 500 kg. Engine starting and taxi fuel = 1 000 kg. The maximum take-off mass is equal to:

Accepted Answer

120 900 kg

Answer

113 900 kg

Answer

121 300 kg

Answer

120 300 kg

Question 4

The reference about which centre of gravity moments are taken is the

Accepted Answer

Datum.

Answer

Chord line

Answer

Centre of mass

Answer

Centre of pressure

Question 5

Length of the mean aerodynamic chord = 1 m Moment arm of the forward cargo: -0,50 m Moment arm of the aft cargo: + 2,50 m. The aircraft mass is 2 200 kg and its centre of gravity is at 25% MAC. To move the centre of gravity to 40%, which mass has to be transferred from the forward to the aft cargo hold?

Accepted Answer

110 kg

Answer

104 kg

Answer

165 kg

Answer

183 kg

Question 6

The total mass of an aeroplane is 145000 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:

Accepted Answer

7 500 kg

Answer

3 500 kg

Answer

35 000 kg

Answer

62 500 kg

Question 7

The centre of gravity of an aeroplane is at 25% of the Mean Aerodynamic Chord.This means that the centre of gravity of the aeroplane is situated at 25% of the length of:

Accepted Answer

The mean aerodynamic chord in relation to the leading edge

Answer

The mean aerodynamic chord in relation to the datum

Answer

The mean aerodynamic chord in relation to the trailing edge

Answer

The aeroplane in relation to the leading edge

Question 8

Fuel loaded onto an aeroplane is 15400 kg but is erroneously entered into the load and trim sheet as 14500 kg. This error is not detected by the flight crew but they will notice that

Accepted Answer

Speed at un-stick will be higher than expected

Answer

V1 will be reached sooner than expected

Answer

V1 will be increased.

Answer

The aeroplane will rotate much earlier than expected.

Question 9

Given:Standard Empty Mass 1764 lbs. Optional Equipment 35 lbs. Pilot + Passenger 300 lbs. Cargo 350 lbs. Ramp Fuel ( Block Fuel) 60 Gal. Trip Fuel 35 Gal. Taxi Fuel 1.7 Gal. Final Reserve Fuel 18 Gal. Fuel density 6 lbs/Gal. Determine the expected landing mass.

Accepted Answer

2589 lbs

Answer

2557 lbs

Answer

2472 lbs

Answer

2599 lbs

Question 10

A revenue flight is to be made by a jet transport. The following are the aeroplane's structural limits:-Maximum Ramp Mass: 69 900 kg-Maximum Take Off Mass: 69 300 kg-Maximum Landing Mass: 58 900 kg-Maximum Zero Fuel Mass: 52 740 kgTake Off and Landing mass are not performance limited. Dry Operating Mass: 34 930 kgTrip Fuel: 11 500 kg Taxi Fuel: 250 kgContingency & final reserve fuel: 1 450 kg Alternate Fuel: 1 350 kgThe maximum traffic load that can be carried is:

Accepted Answer

17 810 kg

Answer

21 070 kg

Answer

21 170 kg

Answer

20 420 kg
