In steady horizontal flight the Cl of an aeroplane is 0.35. A one-degree increase in the AoA increases the Cl by 0.079. A vertical gust of air instantly changes the AoA by two degrees. The new load factor is:

• 1.9

• 1.45

• 0.9

• 0.45

In a gust, which combination of speeds is applicable for the structural strength of an aeroplane in the clean configuration at MSL?

• 28 fps and Vd

• 66 fps at all speeds

• 66 fps and Vb

• 56 fps and Vc

The load factor that determines Va is the:

• (a) gust load factor at 66 fps

• (b) manoeuvring flap limit load factor

• (c) manoeuvring limit load factor

• (d) manoeuvring ultimate load factor

The data that may be obtained from a buffetonset boundary chart is:

• (a) Mmo for various masses and altitudes

• (b) Mcrit for various masses and altitudes

• (c) the low-speed and the high-speed stall Mach numbers for various masses and altitudes

• (d) the low-speed and the high-speed buffet Mach numbers for various masses and altitudes

The manoeuvring load factor positive limit for a utility category light aeroplane in the clean configuration is:

• (a) 6.0

• (b) 4.4

• (c) 2.5

• (d) 3.8

Two aeroplanes at different masses execute a 20◦ banked turn at 150 kt IAS. The heavier aeroplane will:

• (a) have a greater rate of turn than the lighter aeroplane

• (b) turn at the same radius as the lighter aeroplane

• (c) have a larger turn radius than the lighter aeroplane

• (d) have a smaller radius of turn than the lighter aeroplane

To maintain altitude and speed when an aeroplane is rolled into a turn the pilot must

(i) . . .. . .. . .. . .the thrust:

(ii) . . .. . .. . .. . .. . .the angle of attack.

• (a) (i) maintain; (ii) increase

• (b) (i) increase; (ii) increase

• (c) (i) increase; (ii) maintain

• (d) (i) increase; (ii) decrease

The limiting load factor for a large transport aeroplane in the manoeuvring diagram is:

• (a) 2.0

• (b) 4.4

• (c) 6.0

• (d) 2.5

Two identical aeroplanes mass 1500 kg commence a 20◦ banked turn. Aeroplane A flies at 130 kt and aeroplane B flies at 200 kt. Which of the following statements is correct?

• (a) The load factor for A is greater than the load factor for B.

• (b) The turn radius for A is greater than the turn radius for B.

• (c) The Cl for A is smaller than the Cl for B.

• (d) The rate of turn for A is greater than the rate of turn for B.

Given: TAS 300 kt; Bank angle 45◦; g = 10 m/s2. The turn radius is:

• (a) 2387 m

• (b) 4743 m

• (c) 9000 m

• (d) 3354 m
