031- Mass and Balance

Note: The correct answer under (a) during the exam order answers will be different.

Q.1. The maximum certificated taxi (or ramp) mass is that mass to which an aeroplane may be loaded prior to engine start. It is:
a- A fixed value which is listed in the Flight Manual.
b- A value which varies with airfield temperature and altitude. Corrections are listed in the Flight Manual.
c- A value which varies only with airfield altitude. Standard corrections are listed in the Flight Manual.
d- A value which is only affected by the outside air temperature. Corrections are calculated from data given in the Flight Manual

Q.2. If the eroplane is at a higher mass than anticipated, for a given airspeed the angle of attack will:
a- Be greater, drag will increase and endurance will decrease.
b- Be decreased, drag will decrease and endurance will increase.
c- Remain constant, drag will decrease and endurance will decrease.
d- Remain constant, drag will increase and endurance will increase.

Q.3. An aeroplane has a mean aerodynamic chord (MAC) of 134.5 inches. The leading edge of this chord is at a distance of 625.6 inches aft of the datum. Define the location of the centre of gravity of the aeroplane in terms of percentage MAC if the mass of the aeroplane is acting vertically through a balance arm located 650 inches aft of the datum.
a- 18,1%.
b- 75,6%.
c- 85,5%
d- 10,5%

Q.4. On an aeroplane without central fuel tank, the maximum Zero Fuel Mass is related to:
a- The bending moment at the wing root.
b- Maximum Structural Take-Off Mass.
c- Wing loaded trip fuel.
d- Variable equipment for the flight.


Q.5. Assume:Aircraft actual mass: 4750 kg Centre of gravity at station: 115.8.What will be the new position of the centre of gravity if 100 kg is moved from the station 30 to station 120?:
a- Station 117.69
b- Station 118.33.
c- Station 120.22.
d- Station 118.25.
