25
Why is there a static port on both sides of the aircraft?
Because side slip will give a false reading
26
What is the job of the baffle plate in the probe?
To prevent water or FOD entering
27
Why are the called pitot tubes?
After the french inventor
28
What does ADIRU stand for?
Air data inertial reference unit
29
When would the altitude alert system activate?
When the aircraft deviates more than 300ft
30
What are the two types of memory for modern flight recorders?
- magnetic tape | - solid state memories
31
How long does the flight recorders hold memory for?
25 flight hours
32
Where and why is the flight recorder located?
In the tail section because it takes less damage in a crash
33
Why is the flight recorder painted in bright colours?
So it can be easily seen
34
What must the flight recorder be able to withstand?
1,000G and 1,000°C
35
The flight recorder transmits audio signal to what strength?
40kHz
36
When and how long do flight recorders transmit underwater?
Automatically when it hits the water and for 30 days
37
What are the three types of gyros?
- vertical gyro - directional gyro - rate gyro
38
What is meant by gyro precession?
When a force acts on a gyro and it shifts 90°
39
What is meant by degree of freedom?
The amount of axis a Gyro can spin around
40
How many degrees of freedom does a gyro with two gimbals have?
3
41
When does a gyro completely stop?
20 minutes after shutdown
42
If you cannot wait to remove a gyro that has stopped, what must you do?
Remove it at high speeds
43
Why cant you remove a gyro at medium speeds?
Because it may cause it to tumble
44
What gyro does the artificial horizon use?
A vertical gyro
45
What is meant by true north?
Geographic North Pole
46
What is meant by magnetic north?
The magnetic North Pole
47
What is the angle between true north and magnetic north called?
The variation
48
What is the lubber line?
The line that shows your heading on a compass
49
What is meant by compass north?
When the compass changes magnetic north to a new location due to being affected by magnetic fields
50
What is meant by deviation on a compass?
The difference between magnetic north and compass north
51
What are small adjustable magnets inside a compass used for?
To compensate for deviation
52
What is it called when small adjustable magnets are used inside of the compass?
Compass compensation
53
What does a flux valve do?
It transfers the magnetic field into electrical signal
54
Where are the flux valve located?
Far away from the aircraft magnetic field (wing tips or fin)
55
What does ECAM stand for?
Electronic centralised aircraft monitoring
56
What does EICAS stand for?
Engine indication and crew alerting system
57
Where would you find the EFIS?
The two screens in front of the pilots
58
Where would you find the ECAM/EICAS?
On the centre instrument panel
59
To improve reliability what should you do to the EFIS?
Put the brightness to minimum or off
60
What are the EFIS displayed split into?
- primary flight display | - navigation display
61
What is the layout of the basic T?
Airspeed - left Artificial horizon - centre Altitude - right Heading - bottom
62
In a modern PFD where is the mach number located and how is it expressed?
In the bottom left as a percentage
63
How is dynamic pressure denoted?
Pq
64
How is static pressure denoted?
Ps

4
68
Describe a master warning light?
Flashing red light with continuous aural warning
69
Describe a master caution light?
Steady ambler light with a single aural Warning
70
Where would you find the master warning and caution lights?
In front of the pilots
71
