3) Which of the following flap designs is generally acknowledged to be the mostefficient at increasing the coefficient of lift?
A Simple flaps
B Fowler flaps
C Split flaps
D Slotted flaps
4) What is the name given to the design that combines the horizontal tailplane with the elevator?
A Stabilator
B Stabiliser
C Stabileze
D Varieze
9) The largest moment (i.e. Turning effect) of the vertical fin will occur when:
A the centre of gravity is forward
B the centre of gravity is aft
C the centre of gravity is central
D the centre of gravity is slightly aft of central
11) In a spin, what does the balance ball show?
A It will show the direction of the spin by being thrown towards the wing that is highest
B It will show the direction of the spin by falling towards the wing that is lowest
C It will not show the direction of the spin reliably
D It will show the opposite direction to the spin by being thrown outwards by centripetal force
12) When turning to port, the port aileron will:
A move up
B move down
C move left
D move in the same direction as the starboard aileron
14) The coefficient of lift can be increased by the use of flaps. What percentage increase can be achieved in typical light aircraft?
A Up to 10-20%
B Up to 100%
C Up to 250%
D Up to 400%
15) Which of the following propeller characteristics would be most efficient at a high propeller rpm and low airspeed?
A Fine pitch
B Medium pitch
C Medium to coarse pitch
D Coarse pitch
2) Does the use of flaps affect the aircraft's lateral stability?
A No, because they are lowered symmetrically
B No, because they have a mechanically limited range
C Yes, because they move the effective centre of lift away from the wing tips
D Yes, they increase the stability because the wings produce more lift
5) What will be the effect on the elevators and pitch attitude of the aircraft if you adjust the elevator trim tab so that it points down?
A There will be no significant effect on aircraft pitch
B The elevators will pitch up causing the aircraft to pitch up
C The elevators will pitch up causing the aircraft to pitch down
D The elevators will pitch down causing the aircraft to pitch up
9) Which type of flap works by increasing the effective wing area?
A Simple flaps
B Split flaps
C Fowler flaps
D Differential flaps
10) What is anhedral?
A Angling forwards of the wings from the wing root to the wing tip
B Angling up of the wings from the fuselage to the wingtips
C Angling of the wings backwards to the rear of the aircraft
D Angling down of the wings from the fuselage to the wingtips
13) With reference to an aircraft propeller turning at a steady speed, how does the angular velocity differ between the blade root and the blade tip?
A It increases initally, then decreases after the maximum blade angle is reached
B It increases from the blade root to the blade tip
C It decreases from the blade root to the blade tip
D It stays constant from the blade root to the blade tip
14) Which of the following is NOT an example of an aerodynamic balance which is primarily designed to reduce control loads on the pilot?
A A horn balance
B A mass balance
C An inset hinge
D A balance tab
16) Stability around the lateral axis is called:
A longitudinal stability
B lateral stability
C normal stability
D essential stability
