26
When measuring the deflection angle of the elevator, and before the elevator can be in zero position, what is the position of the moveable stabiliser?
The moveable stabiliser must be in the moveable position
27
Following repairs to the flight control surface, adjustments would need to be made to achieve what?
Static balancing
28
What is the purpose of a pylon?
To attach the engine to the airframe/wing
29
How many attachment points does the pylon have to the wing?
3
30
Which supply sources are used to supply the AC system?
APU, Engines and Ground powered air supply
31
What is the role of the pneumatic controller?
Monitor pressure and temperature, to register leaks and to monitor the operation of the pneumatic components
32
How does a vapour-cycle machine cool the pneumatic flow?
A special cooling fluid is compressed and expanded in a closed circuit
33
The recirculation system…
Recirculates cabin air to reduce the pack airflow
34
In an ideal situation, what is the best condition for the aircraft structure with regard to pressurisation?
The best condition for aircraft structure would be no pressurisation during flight
35
Why would an OUTFLOW valve have 2 AC motors and 1 DC motor?
Each pressure controller can control its own AC motor and if AC is not available the DC motor can control the valve
36
What 2 conditions can cause an equipment cooling system override operation to happen?
Component failure or smoke detected
37
What will happen if cabin altitude reaches 15000ft?
Outflow valves automatically closes
38
What type of gyro would be used to indicate the aircraft’s altitude?
Vertical gyro
39
Modern flight data recorders…
Store the flight data from the last 25 hours of flight for accident investigation purposes
40
Vertical gyros have…
3 degrees of freedom with a vertical spin axis
41
What does the airspeed indicator indicate?
It shows the indicated airspeed (IAS) which is the reference for all aerodynamic parameters e.g. lift and drag
42
What does the inner loop of an auto pilot control?
It controls the altitude of the aircraft and is always active
43
Which signal is used to dampen Dutch roll oscillations?
Yaw rate
44
Which method is used to disconnect the auto-throttle system?
Pushing either throttle lever disconnect button
45
What is the VHF emergancy frequency?
121.5MHz
46
Which statement is true for ACARS?
It is used for manual and automatic data transfers between the aircraft and the ground in both directions
47
What does the 1KHz tone indicate on a HF system?
It indicates that the antenna coupler is tuning to the newly selected frequency
48
Which priority sequence is used in a Passenger Address (PA) amplifier?
1. Cockpit crew 2. Cabin crew 3. Pre-recorded announcements 4. Boarding music
49
How does DME measure distance?
The time between the interrogation and reply signal is proportional to the distance of the station
50
Which statement correctly describes the VOR principle?
The VOR receiver calculates the magnetic bearing from 2 signals transmitted by a ground station
51
What is the purpose of the 2 antennas fitted in an ADF system?
2 antenna signals are required to determine the correct direction
52
What indicates localiser deviation?
HSI and ADI
53
Why is an integral grey collar fitted to certain CBs?
To indicate that they must be pulled by maintenance personnel during maintenance work
54
Which statement is correct regarding the hot battery bus bar?
It is always directly connected to the battery
55
Why is an integral orange collar fitted to certain CBs?
To indicate that they must be pulled by flight crew in certain abnormal situations
56
Why must you never attempt to carry out too many APU starts immediately after one another?
It will overheat the battery and damage it
57
What should you do if the electrolyte used in a Ni-Cd battery comes into contact with human skin?
Rinse it immediately making sure you only use clean water
58
