Principles of Flight - ATPL - Airline Transport Pilot license

Test 10 Questions ATPL - Airline Transport Pilot license - Principles of Flight, no time limit

1 - The regime of flight from the critical Mach number up to approximately M = 1.3 is called the: Supersonic range Transonic range Subsonic range Hypersonic range

2 - The angle of attack of a fixed pitch propeller blade increases when: Velocity and RPM increase Forward velocity increases and RPM decreasing RPM increases and forward velocity decreases Velocity and RPM decrease

3 - Which of the following will reduce induced drag? Low aspect ratio Elliptical lift distribution Extending the flaps Flying at high angles of attack

4 - An aeroplane transitions from steady straight and level flight into a horizontal co-ordinated turn with a load factor of 2, the speed remains constant and the: Induced drag increases by a factor of 4 Total drag increases by a factor of 4 Lift increases by a factor of 4 Angle of attack increases by a factor of 1/4

5 - When Fowler type trailing edge flaps are extended at a constant angle of attack, the following changes will occur: CL increases and the centre of pressure moves forward CL and CD increase CD decreases and the centre of pressure moves aft CL increases and CD remains constant

6 - Dihedral of the wing: Is only positive for aeroplanes with high mounted wings. Is the only way to increase the static lateral stability. Decreases the static lateral stability. Increases the static lateral stability.

7 - A boundary layer fence on a swept wing will: Improve the high speed characteristics Improve the low speed characteristics Improve the lift coefficient of the trailing edge flap Increase the critical Mach Number

8 - The wing of an aeroplane will never stall at low subsonic speeds as long as.... The angle of attack is smaller than the value at which the stall occurs There is a nose-down attitude The CAS exceeds the power-on stall speed The IAS exceeds the power-on stall speed

9 - The boundary layer of a wing is: A turbulent flow around the wing Created by the normal shock wave at transonic speeds Caused by suction on the upper wing surface A layer on the wing in which the stream velocity is lower than the free stream velocity

10 - What wing shape or wing characteristic is the least sensitive to turbulence: Swept wings Elliptical wing Wing dihedral Straight wings
