Question 1

Slat extension will:

Accepted Answer

Increase the critical angle of attack

Answer

Reduce tip vortices

Answer

Create gaps between leading edge and engine nacelles

Answer

Decrease the energy in the boundary layer on the upperside of the wing

Question 2

A four-engine jet has identical, symmetrically placed wing-mounted engines producing equal thrust. During the take-off roll, a strong crosswind from the left produces a left-yawing weathercock moment. Considering this moment and the yawing moment from asymmetric thrust, which single engine failure above V1 gives the greatest combined left-yawing tendency?

Accepted Answer

The left outboard engine

Answer

The right outboard engine

Answer

The left inboard engine

Answer

The right inboard engine

Question 3

Examples of aerodynamic balancing of control surfaces are:

Accepted Answer

A sealed internal aerodynamic balance panel and a horn balance.

Answer

Upper and lower rudder, seal between wing's trailing edge and leading edge of a control surface

Answer

Fowler flaps, upper and lower rudder

Answer

Weight in the nose of the control surface, horn balance

Question 4

The use of a slot in the leading edge of the wing enables the aeroplane to fly at a slower speed because:

Accepted Answer

It delays the stall to a higher angle of attack

Answer

The laminar part of the boundary layer gets thicker

Answer

It decelerates the upper surface boundary layer air

Answer

It changes the camber of the wing

Question 5

When flaps are extended in a straight and level flight at constant IAS, the lift coefficient will eventually:

Accepted Answer

Remain the same

Answer

Increase

Answer

Decrease

Answer

First increase and then decrease

Question 6

In the classical design model where a published VA is chosen at MTOW as the intersection of the positive stall boundary and manoeuvring limit-load line, VA is:

Accepted Answer

The speed at which the aeroplane stalls at the manoeuvring limit load factor at MTOW.

Answer

The speed at which unrestricted application of elevator control can be used, without exceeding the maximum manoeuvring limit load factor

Answer

The maximum speed in smooth air

Answer

Just another symbol for the rough air speed

Question 7

During a phugoid the speed:

Accepted Answer

Varies significantly, whereas during a short period oscillation it does not.

Answer

Remains approximately constant, as during a short period oscillation.

Answer

Remains approximately constant, whereas during a short period oscillation it varies significantly.

Answer

Varies significantly, as during a short period oscillation.

Question 8

The boundary layer of a wing is:

Accepted Answer

A layer on the wing in which the stream velocity is lower than the free stream velocity

Answer

A turbulent flow around the wing

Answer

Created by the normal shock wave at transonic speeds

Answer

Caused by suction on the upper wing surface

Question 9

For a constant-speed propeller within its governing range, with selected RPM and engine power unchanged, which statement is correct when airspeed increases?

Accepted Answer

The blade angle increases with increasing aeroplane speed

Answer

The RPM decreases with increasing aeroplane speed

Answer

The propeller system keeps the aeroplane speed constant

Answer

The selected RPM is kept constant by the manifold pressure

Question 10

The aeroplane drag in straight and level flight is lowest when the:

Accepted Answer

Parasite drag is equal to the induced drag

Answer

Induced drag is equal to zero

Answer

Parasite drag equals twice the induced drag

Answer

Induced drag is lowest
