Test 10 Questions ATPL - Airline Transport Pilot license - Mass and Balance, no time limit

1 - The Dry Operating Mass is the total mass of the aircraft ready for a specific type of operation but excluding Usable fuel and traffic load. Usable fuel, potable water and lavatory chemicals. Potable water and lavatory chemicals. Usable fuel and crew.

2 - The responsibility for determination of the mass of 'operating items' and 'crew members' included within the Dry Operating Mass lies with The authority of the state of registration. The commander. The person compiling the weighing schedule. The operator.

3 - . When has the centre of gravity to be computed? At least every four years After every 400-hrs inspection During every yearly inspection Prior to every flight

4 - Which of the following corresponds to zero fuel mass? Operating mass plus luggage of passengers and cargo. Operating mass plus passengers and cargo. The take-off mass of an aeroplane minus all usable fuel. Take-off mass minus fuel to destination and alternate.

5 - The empty mass of an aeroplane is given as 44800 kg. Operational items (including crew standard mass of 1060 kg) are 2300 kg. If the maximum zero fuel mass is given as 65500 kg, the maximum traffic load which could be carried is: 23000 kg 20700 kg 19460 kg. 18400 kg

6 - When the centre of gravity is at the forward limit, an aeroplane will be: Extremely stable and require small elevator control to change pitch. Extremely stable and will require excessive elevator control to change pitch. Extremely unstable and require small elevator control to change pitch. Extremely unstable and require excessive elevator control to change pitch.

7 - From the Loading Manual for the transport aeroplane, the maximum load that can be carried in that section of the aft cargo compartment which has a balance arm centroid at:

835.5 inches is 6752 kg 835.5 inches is 3062 kg 421.5 inches is 2059 lbs 421.5 inches is 4541 kg

8 - The empty mass of an aircraft is recorded in The loading manifest. It differs from Dry Operating Mass by the value of the 'useful load'. The weighing schedule. If changes occur, due to modifications, the aircraft must be re-weighed always. The loading manifest. It differs from the zero fuel mass by the value of the 'traffic load'. The weighing schedule and is amended to take account of changes due to modifications of the aircraft.

9 - The floor of the main cargo hold is limited to 4000 N/m2.It is planned to load a cubic container each side of which measures 0.5 m. Its maximum gross mass must not exceed:(assume g=10m/s 2) 1000 kg 100 kg 5000 kg 500 kg
