A loaded aircraft has its centre of gravity (CG) 35 inches aft of the datum, and its mass is 4 500 Ib. A last minute load of 334 Ib is placed on board 20 inches forward of the datum.

Refer to figure…

At a given take-off mass of a transport aeroplane, 13% MAC corresponds to a balance arm of 32.25 m aft of the datum. Using the information in the annex, calculate the length of the MAC of this aeroplane:

Refer to figure.

You are about to depart for a domestic commercial flight, with an aircraft having a capacity of 2

flight crew members and 10 passengers. As part of your pre-flight calculations, you need to compute

the Traffic Load in accordance with standard passenger and baggage masses as defined in the annex. What is the Traffic Load, given the following information?

Flight crew: 2

Male passengers: 2

Female passengers: 3

Baggage: 6 pieces, with a total mass of 63 kg

Hand baggage: 3 pieces

Standard mass for a flight crew member: 85 kg

Refer to figure.

Using the annex, determine the maximum allowable mass and running load of the middle compartment of the forward cargo hold.

Refer to figure.

Cross-check the information contained in the load/trim sheet of a Medium Range Jet Commercial Air Transport (MRJT) aeroplane. Which of the following masses/loads is correctly computed?

Refer to figure.

Using the annex, determine the CG position and the moment at Basic Empty Mass. The CG position is…..

Calculate the centre of gravity in % MAC (mean aerodynamic chord) with following data:

Distance datum - centre of gravity: 12.53 m

Distance datum - leading edge of the MAC: 9.63 m

Length of MAC: 8 m.

Refer to figure.

A turboprop aeroplane having 36 passenger seats operates a domestic Commercial Air Transport flight carrying a rugby team of 28 sportsmen. Each of these players has one checked baggage and the average mass of these people is 115 kg. Determine the mass of the Traffic Load for this flight.

An aeroplane with one nose landing gear and two main landing gears is weighed on jacks. Determine the aircraft BEM and CG position, using the following readouts:

Nose landing gear, located at 161 inches from datum reading: 2300 kg

Each main landing gear, located at 775 inches from datum reading: 19300 kg

An aeroplane has a MAC of 3.08 m and a Leading Edge MAC (LEMAC) of 14.72 m aft of datum. If the CG position of that aeroplane is located 16.13 m aft of datum, what is the CG position in % MAC?
