Test 10 domande ATPL - Airline Transport Pilot license - Principles of Flight, tempo libero

1 - By what percentage does VA (EAS) alter when the aeroplane's weight decreases by 19%? 10% lower. 19% lower. No change 4.36% lower.

2 - What is the effect of high aspect ratio of an aeroplane's wing on induced drag? It is increased because high aspect ratio has greater frontal area It is reduced because the effect of wing-tip vortices is reduced It is increased because high aspect ratio produces greater downwash It is unaffected because there is no relation between aspect ratio and induced drag

3 - What will happen in ground effect? The wing tip vortices increase in strength The wing downwash on the tail surfaces increases The thrust required will increase significantly The induced angle of attack and induced drag decrease

4 - 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

5 - An aeroplane is in a level turn, at a constant TAS of 300 kt, and a bank angle of 45°. Its turning radius is:(given: g= 10 m/s 2) 4743 metres. 9000 metres. 2381 metres. 3354 metres.

6 - The stall speed in a 60° banked turn increases by the following factor: 1.41 2.00 1.30 1.07

7 - The aerodynamic centre of the wing is the point, where: Changes of lift due to variations in angle of attack are constant. Aerodynamic forces are constant. The pitching moment coefficient does not vary with angle of attack. The aeroplane's lateral axis intersects with the centre of gravity.

8 - Positive static lateral stability is the tendency of an aeroplane to: Roll to the right in the case of a positive sideslip angle (aeroplane nose to the left). Roll to the right in a right turn. Roll to the left in the case of a positive sideslip angle (aeroplane nose to the left). Roll to the left in a right turn.

9 - When an aeroplane is flying at an airspeed which is 1.3 times its basic stalling speed, the coefficient of lift as a percentage of the maximum lift coefficient (CLmax) would be: 130% 169% 59% 77%

10 - Consider an aerofoil with a certain camber and a positive angle of attack. At which location will the highest flow velocities occur? Upper side In the stagnation point In front of the stagnation point Lower side
