25
A fire detection loop must be capable of
Using master warning visual and aural signals
26
A thermocouple fire detector
Produces a DC supply when fire is detected
27
A fire detection system can pass through one zone to another providing
The system is protected
28
A fire detection system should be
Positioned in a location determined by the manufacturer during the design
29
In overheat conditions the resistance of the resistive type fire wire
Decreases
30
Fire wires
May have one or both ends connected to the control box depending on type
31
A fire detection zone wiring can pass through another fire zone when
The system and the extinguishing are the same
32
The apu fire shut off valve is normally
Normally electrically operated as the apu is electrically shut down by its own monitoring system
33
A fire test is carried out and the test button is released but the light remains on this is because
There is a fire
34
A fire that can be put out by a crew member in a cargo bay is in a
Class b compartment
35
A short circuit on a capacitive type fire detection element will result in
System does not work and no readings
36
A Systron dinner fire detection system used
Helium gas
37
A toilet is fitted with thermal protection
To protect against the dangers of smoke and fire in the event of of an overheat
38
Chemical fire extinguishers extinguish fires by
Reacting with the oxygen in the air or the flame rendering it inert
39
Continuous type fire wire detector system operates on the principle of an increase in temperature causing
A decrease in resistance
40
Engine fire bottle pressure at 70f is
600psi +- 25
41
Engine fire bottle pressure switches are operated by
DC
42
Engine wing fire bottles should be charged with nitrogen at 15c to
600psi
43
Fire extinguishment must kept within temperature limits
To minimise possibility or discharge at high temperatures
44
Fire resistance requirements for helicopter fabrics are in
CS29
45
A fire test on aircraft internal furnishings must be carried out
Only when equipment items fail random tests
46
Fireproofing of cabin material should be done
When a sample fails
47
First digit number of halogenated hydrocarbon extinguishers represents the number of
Carbon atoms
48
For multi engined rotorcraft the quantity of fire extinguishing agent available must
Provide at least two discharges for each fire zone
49
In a capacitive fire detection system if
There is a break the system will work but not test satisfactory
50
In a gas FireWire system what causes the FireWire caption to come on when heat is applied
Pressure
51
In a single continuous loop fire detector test
Current is passed down the centre conductor
52
In a toilet smoke condition what would be the indication
Either a light or an audible warning in the cabin
53
In the event of a crash landing
Most fire bottles are set off automatically
54
In the event of a fire being caused by the oxygen supply
Oxygen supply must be stopped
55
In which of the following would expect to find a smoke detector
Battery bay
56
Information on cabin furnishings fire protection requirements can be found in
CAP 747
57
Insulation resistance check of a continuous type fire wire detector element should be carried out
To include the element it’s sensing amplifier and associated relays
58
Lavatories must have in the disposal container
Freon extinguisher with black ball markings indicating when discharged
59
On pulling the fire handle the aural warning
Goes off the light remains on the generator goes offline
60
Smoke detectors consist of a
Photoelectric cell detecting 10% smoke
61
The fire detection system of an aircraft must contain
Approved quick acting fire or overheat detectors in each designated fire zone
62
The outside casing of a fire wire has
Same potential as ground
63
Toilet fire detection issues can be found in
AWN 83 (Now transferred to cap 747 GR no 20)
64
Toilet smoke detector activate
A warning light and or indication in the cabin
65
What do you check when carrying out an insulation check on a continuous FireWire loop

66
What external warning is there for an apu fire
Both aural and red light
67
What is the contamination monitor for in a Systron dinner fire detection system
Dirty contacts
68
What is used to measure squib resistance of a fire bottle
Safety ohmmeter
69
What test is carried out to ensure serviceability of a squib
A continuity check
70
What type of gas is used as a propellant for a high rate of discharge extinguishing system
Nitrogen
71
When a fire test on a Systron donner fire detector system is carried out
It checks the integrity of the contacts
72
When testing a squib for insulation
Short all pins together then test between them and the case
73
When the external apu fire switch is selected what happens
Fuel shut off Electrical power cut off Bleed air cut off Fire bottle operated
74
When the fire handle is operated it
Cuts of field current, hydraulics and fuel and operates fire extinguishers
75
When the fire handle is pulled a
Red warning light stays on generator hydraulics and fuel is cut off
76
Which areas of a civil transport aircraft would have smoke detectors fitted
Freight holds baggage compartments and equipment bags
77
With the gas operated type of fire wire a local very high temperature will cause
An avalanche gas to be given off
78
You would expect to find a squib connected to
