Principles of Flight - ATPL - Airline Transport Pilot license

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

1 - 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

2 - An aeroplane exhibits static longitudinal stability, if, when the angle of attack changes: The change in total aeroplane lift acts through the centre of gravity The resulting moment is positive The change in total aeroplane lift acts aft of the centre of gravity The change in wing lift is equal to the change in tail lift

3 - An aeroplane, with a C.G. location behind the centre of pressure of the wing can only maintain a straight and level flight when the horizontal tail loading is: Zero. Downwards. G. location behind the centre of pressure of the wing can only maintain a straight and level flight when the horizontal tail loading is: zero. downwards. upwards. Upwards or downwards depending on elevator deflection.

4 - How does positive camber of an aerofoil affect static longitudinal stability? Positive effect, because the centre of pressure shifts rearward at increasing angle of attack No effect, because camber of the aerofoil produces a constant pitch down moment coefficient, independent of angle of attack Positive effect, because the lift vector rotates backward at increasing angle of attack Negative effect, because the lift vector rotates forward at increasing angle of attack

5 - Which aeroplane behaviour will be corrected by a yaw damper ? Tuck under. Dutch roll. Buffeting. Spiral dive.

6 - A conventional stabiliser on a stable aeroplane in a normal cruise condition: 1 - always provides negative lift.2 - contributes to the total lift of the aeroplane.3 - may stall before the wing, in icing conditions, with large flap settings, unless adequate design and/or operational precautions are taken.4 - is necessary to balance the total pitch moment of the aeroplane. Which of the following lists all the correct statements ? 2, 3 and 4 1 and 4 1 and 3 1, 3 and 4

7 - The value of the induced drag of an aeroplane in straight and level flight at constant weight varies linearly with: V2 1/V2 1/V V

8 - Which kind of ''tab'' is commonly used in case of manual reversion of fully powered flight controls ? Servo tab Anti-balance tab Balance tab Spring tab

9 - During the take-off roll with a strong crosswind from the left, a four engine jet aeroplane with wing mounted engines experiences an engine failure above V1. Which engine causes the greatest control problem? The right outboard engine The left outboard engine The left inboard engine The right inboard engine

10 - Which formula or equation describes the relationship between force (F), acceleration (a) and mass (m)? M=F.a A=F. m F=m. a F=m / a
