A300 Classic SKV Fire Detection and Protection

Question 1

What does the fire detection loop arrangement of the engine consist of?

Answer 1

Dual loops of three elements each

Question 2

How were the engine fire detection loops designed?

Answer 2

If both loops are working, both loops must sense an excessive temperature rise to generate a fire signal.

Question 3

In the Fire Protection system, what is the difference between the two lower cargo fire bottles?

Answer 3

Bottle #2 is metered (up to 30 min), bottle #1 empties immediately

Question 4

How many bottles of fire extinguishing agent are each engine and lower compartments equipped with?

Answer 4

Two bottles per engine and two bottles for all lower cargo compartments

Question 5

What is the minimum power source needed to discharge an engine fire extinguishing bottle?

Answer 5

Hot Battery Bus

Question 6

When the Engine Fire Detection System is operating in single loop mode, when will an engine fire be detected?

Answer 6

If any three elements of the remaining loop senses an excessive temperature rise, a fire signal is generated

Question 7

After an engine fire is detected, when will the lights in the Engine Fire Handle extinguish?

Answer 7

Once the fire is no longer detected

Question 8

The primary purpose of the Sniffer Fan is to provide confirmation of smoke in what part of the aircraft?

Answer 8

Avionics compartment and Minimum Equipment Bay

Question 9

When the aircraft is on the ground and an APU fire is detected, what will also occur?

Answer 9

The APU is automatically shut down and after a 10 second delay, the fire bottle is automatically discharged

Question 10

What does the APU fire protection system consist of?

Answer 10

One fire bottle powered by the DC ESS bus

Question 11

What is required to generate a Main Deck smoke warning if one of the Loop switches in a zone is selected off?

Answer 11

Only the remaining loop (A or B) in that zone is required to detect smoke

Question 12

What fire protection system is provided for the Main Cargo Deck?

Answer 12

Fire can only be suppressed by cutting off airflow, there are no fire extinguishers available

Question 13

What indicates smoke in the Minimum Equipment Bay?

Answer 13

Red SMOKE light on the MIN EQPT circuit breaker panel

Question 14

What is the minimum power source needed to discharge a cargo fire extinguishing bottle?

Answer 14

Hot Battery Bus

Question 15

The lower cargo compartments have what type of fire detection/protection?

Answer 15

Automatic smoke detection and manual fire extinguishing

Question 16

What must occur for the APU fire detection system to generate a fire signal?

Answer 16

If one loop is selected OFF, the remaining operable sensor in the active loop must sense an excessive temperature rise to generate a fire signal.

Question 17

What happens when smoke is detected by the main deck smoke detection systems?

Answer 17

The Air Conditioning system closes valves to isolate the cargo compartment

Question 18

What is the difference in the fire protection systems of the main deck and lower cargo compartments?

Answer 18

Lower cargo has fire extinguishing bottles, main deck does not
