Question 6

Which option correctly identifies where smoke detectors are used on an aeroplane, based on the following list?

1. Engines
2. APU
3. Cargo holds
4. Toilet compartments
5. Avionics bays
6. Crew rest facilities

Answer 6

3456

Question 7

Failure of a capacitive fuel indication system will be indicated by…

Answer 7

Empty

Question 8

What zone is the fire prevention and detection located in, within the engine?

Answer 8

Cold zone.

Question 9

A heat loop fire wire uses increase/ decrease in capacitance and increase/ decrease in resistance

Answer 9

Increase in capacitance and decrease in resistance

Question 10

HEAT LOOP FIRE WIRE
Blank in voltage indicates a fault
Blank in voltage indicates a fire

Answer 10

Decrease = fault
Increase = fire

Question 11

The capacitance type fuel gauging system indicates the fuel quantity by measuring… The dielectric change between blank and blank.

Answer 11

The dielectric change between fuel and air.

Question 12

In a gaseous loop
High pressure = x
Low pressure = x

Answer 12

High = fire
Low = fault

Question 13

Answer 13

2

Question 14

What is the working principle of a gaseous fire detection system?

Answer 14

Pressure.

Question 15

When a part of a continuous loop fire detection system is heated:

1. its resistance decreases
2. its resistance increases
3. the current increases
4. the current decreases

The combination that regroups all of the correct statements is…

Answer 15

13

Question 16

Regarding a built-in fire extinguishing system of a turbine engine, what statement(s) is/are correct or incorrect?

1. A bleed-air driven (pneumatic) pump is used to discharge the fire agent into the engine compartment
2. The built-in fire-extinguishing system is capable of extinguishing an engine fire WITHOUT engine shutdown

Answer 16

Incorrect

Question 17

Generally, when the fire handle of the engine fire-extinguishing system on an aeroplane is pulled, the effects are:

1. opening of the bleed air valves and HP valves on the engine concerned
2. arming of the extinguishing system
3. immediate discharge of extinguishing agent
4. deactivation of the electric generators

The combination that regroups all of the correct statements is…

Answer 17

24

4. A special oxygen reservoir is used containing diluted oxygen

Answer 18

13

Question 19

What substance must never be used in the vicinity or on parts of an oxygen installation?

Answer 19

Grease or oil
