Question 1

A swept wing stalls at a higher speed than an equivalent un-swept wing due to -

Answer 1

increased spanwise flow

Question 2

Why is stalling speed relatively higher for an aircraft with wing sweep? Because of the effective:

Answer 2

Decrease in chord-wise airflow.

Question 3

The purpose for a large commercial turbo jet aeroplane extending leading edge slats during approach is to increase:

Answer 3

CL by controlling chord-wise airflow over the wings.

Question 4

A typical flight control system as in the B767-300ER uses 3 separate and independent hydraulic systems to power flight controls, all functions are normal, which systems are pilot controls powered from?

Answer 4

All systems at all times

Question 5

Which component in the hydraulic system can prevent excessive hydraulic fluid loss?

Answer 5

Hydraulic fuse

Question 6

Stator vanes in an axial flow compressor convert airstream velocity into pressure by use of:

Answer 6

Divergent passages

Question 7

In gas turbine engines, effective power in reverse thrust is less than forward thrust for the same throttle angle because during reverse:

Answer 7

Exhaust gas discharge angle is aerodynamically limited.

Question 8

What are some warning flags that appear on a conventional ADI?

Answer 8

GS, gyro and computer

Question 9

In an aircraft without a digital data bus, the autopilot altitude information for altitude hold mode is taken from:

Answer 9

The autopilot aneroid.

Question 10

In a B767-300ER with 3 autopilots, for a fail operational auto-land approach, the number of separate electrical systems required to power the autopilots is:

Answer 10

3 AC/DC systems.

Question 11

A typical FMS incorporates two FMCs and two EHSIs. The pilot both have the MAP mode displayed on their respective EHSIs but have different range scales selected. The left FMC suddenly fails but the crew does NOT intervene with any manual corrective action. Which of the following statements is correct regarding the display on the left EHSI after the failure?

Answer 11

It will display MAP failure flag.

Question 12

To achieve max angle of climb to achieve obstacle clearance after takeoff a jet aircraft must climb at:

Answer 12

Min drag speed with zero flap.

Question 13

A large jet transport aircraft is in cruise at high altitude with stabiliser trim set correctly, the position of the elevator would be:

Answer 13

Faired.

Question 14

On the EADI, brown and blue colours disappear because:

Answer 14

The screens are overheating

Question 15

In the auto mode of most pressurisation systems the required inputs from the pilot pre-flight are:

Answer 15

Cruise altitude and destination elevation

Question 16

Under normal pressurisation what will the position of the outflow valve be from takeoff to cruise?

Answer 16

Automatically controlled by the cabin pressure controller.

Question 17

The high pressure turbine on a turbofan, compared to a turbojet of the same thrust output would be:

Answer 17

Smaller because of the smaller mass air flow.

Question 18

With regard to the operation of powered controls in an aircraft with 3 independent hydraulic systems such as a 767-300 ER

Answer 18

all three systems supply the flight controls at all times providing automatic backup

Question 19

The component of an aircraft electrical system providing the initial excitation field for a constant speed PMG type alternator is

Answer 19

the permanent magnet generator or pilot exciter
