Question 1

The BEM of an aircraft is 30000 kg.Given the following data calculate the DOM: Catering = 300 kgCrew = 600 kgTrip Fuel = 1200 kg Unusable Fuel = 30 kg Traffic Load = 2500 kg

Accepted Answer

30900 kg

Answer

30930 kg

Answer

29100 kg

Answer

34630 kg

Question 2

An aeroplane is loaded with its centre of gravity towards the rear limit. This will result in:

Accepted Answer

A reduced fuel consumption as a result of reduced drag

Answer

A reduction in power required for a given speed

Answer

An increased risk of stalling due to a decrease in tailplane moment

Answer

An increase in longitudinal stability

Question 3

Given:Total mass 2900 kgCentre of gravity (cg) location station: 115 Aft cg limit station: 116The maximum mass that can be added at station 130 is:

Accepted Answer

207 kg.

Answer

140 kg.

Answer

317 kg.

Answer

14 kg.

Question 4

. What effect has a centre of gravity close to the most forward limit?

Accepted Answer

A reduced rate of climb capability.

Answer

A better rate of climb capability.

Answer

A reduction in the specific fuel consumption.

Answer

A decreased induced drag.

Question 5

Where is the centre of gravity of the aeroplane in the diagram?

Accepted Answer

26.57 cm forward of datum.

Answer

32.29 cm aft of datum.

Answer

26.57 cm aft of datum.

Answer

32.29 cm forward of datum.

Question 6

The maximum zero-fuel mass: 1- is a regulatory limitation2- is calculated for a maximum load factor of +3.5 g3- is based on the maximum permissible bending moment at the wing root4- is defined on the assumption that fuel is consumed from the outer wings tank first 5- is defined on the assumption that fuel is consumed from the centre wing tank first The combination of correct statements is:

Accepted Answer

1, 3, 5

Answer

2, 3, 4

Answer

2, 3, 5

Answer

1, 2, 3

Question 7

If individual masses are used, the mass of an aircraft must be determined prior to initial entry into service and thereafter

Accepted Answer

At intervals of 4 years if no modifications have taken place.

Answer

Only if major modifications have taken place.

Answer

At regular annual intervals.

Answer

At intervals of 9 years.

Question 8

The maximum load per running metre of an aircraft is 350 kg / m. The width of the floor area is 2 metres. The floor strength limitation is 300 kg per square metre. Which one of the following crates (length x width x height) can be loaded directly on the floor?

Accepted Answer

A load of 400 kg in a crate with dimensions 1.2 m x 1.2 m x 1.2 m.

Answer

A load of 500 kg in a crate with dimensions 1.5 m x 1 m x 1 m.

Answer

A load of 700 kg in a crate with dimensions 1.8 m x 1.4 m x 0.8 m.

Answer

A load of 400 kg in a crate with dimensions 1.4 m x 0.8 m x 0.8 m.

Question 9

Which of the following statements is correct?

Accepted Answer

A tail heavy aeroplane is less stable and stalls at a lower speed than a nose heavy aeroplane

Answer

If the actual centre of gravity is located behind the aft limit of centre of gravity it is possible that the aeroplane will be unstable, making it necessary to increase elevator forces

Answer

The lowest stalling speed is obtained if the actual centre of gravity is located in the middle between the aft and forward limit of centre of gravity

Answer

If the actual centre of gravity is close to the forward limit of the centre of gravity the aeroplane may be unstable, making it necessary to increase elevator forces

Question 10

At a given mass the CG position is at 15% MAC. If the leading edge of MAC is at a position625.6 inches aft of the datum and the MAC is given as 134.5 inches determine the position of the CG in relation to the datum.

Accepted Answer

645.78 inches aft of datum

Answer

605.43 inches aft of datum

Answer

20.18 inches aft of datum

Answer

If the leading edge of MAC is at a position625.6 inches aft of the datum and the MAC is given as 134.5 inches determine the position of the CG in relation to the datum. 605.43 inches aft of datum 20.18 inches aft of datum 228.34 inches aft of datum
