Question 1

In mass and balance calculations the 'index' is:

Accepted Answer

Is a figure without unit of measurement which represents a moment.

Answer

An imaginary vertical plane or line from which all measurements are taken.

Answer

A location in the aeroplane identified by a number.

Answer

The range of moments the centre of gravity (cg) can have without making the aeroplane unsafe to fly.

Question 2

Accepted Answer

33 cm.

Answer

40 cm.

Answer

34 cm.

Answer

30 cm.

Question 3

Dry Operating Mass is the mass of the aircraft less

Accepted Answer

Answer

Traffic load, potable water and lavatory chemicals.

Answer

Usable fuel.

Question 4

A mass of 500 kg is loaded at a station which is located 10 metres behind the present Centre of Gravity and 16 metres behind the datum.(Assume: g=10 m/s^ 2)The moment for that mass used in the loading manifest is:

Accepted Answer

80000 Nm

Answer

50000 Nm

Answer

130000 Nm

Answer

30000 Nm

Question 5

. The moment for an item is

Accepted Answer

The mass of the item multiplied by it's distance from the datum

Answer

The mass of the item divided by it's distance from the datum

Answer

The square of the distance the item is from the datum divided by it's mass

Answer

The distance the item is from the datum divided by it's mass

Question 6

Loads must be adequately secured in order to:

Accepted Answer

Avoid unplanned centre of gravity (CG) movement and aircraft damage.

Answer

Prevent excessive g-loading during the landing flare.

Answer

Avoid any centre of gravity (CG) movement during flight.

Answer

Allow steep turns.

Question 7

The centre of gravity location of the aeroplane is normally computed along the:

Accepted Answer

Longitudinal axis.

Answer

Horizontal axis.

Answer

Lateral axis.

Answer

Vertical axis.

Question 8

Comparing a forward CG position with an aft one, the forward cg position will cause a

Accepted Answer

Decrease in range.

Answer

Decrease in the landing speed.

Answer

Tendency to yaw to the right on take-off.

Answer

Decrease of the stalling speed.

Question 9

Given the following data calculate the CG as a %MAC when 12000N of last minute cargo is added to a hold 10m from the datum:AUM 460000NLEMac 14m from datum MAC 4.6mCurrent CG 15.4m from datum
