Test 10 Questions ATPL - Airline Transport Pilot license - Performance, no time limit

1 - Which of the following factors determines the maximum flight altitude in the 'Buffet Onset Boundary' graph?
2 - Which statement is correct for a descent without engine thrust at maximum lift to drag ratio speed?
3 - In a given configuration the endurance of a piston engine aeroplane only depends on:
4 - What is the result of a large take off flap setting compared to a small take off flap setting on required Take-off Distance (TOD) and the field length limited Take-off Mass (TOM)?
5 - The take-off distance available is:
6 - During climb to the cruising level, a headwind component:
7 - Below the optimum cruise altitude:
8 - A four jet-engine aeroplane (mass = 150 000 kg) is established on climb with all engines operating. The lift-to-drag ratio is 14.Each engine has a thrust of 75 000 Newton. The gradient of climb is: (given: g= 10 m/s 2)
9 - If there is a tail wind, the climb limited TOM will:
10 - Other factors remaining constant and not limiting, how does increasing pressure altitude affect allowable take-off mass?
