Aircraft Smoke Detection and Fire Protection Systems Questions and Answers
- 1.
Smoke detection systems are installed in
- A.
Avionics bay and cargo compartment
- B.
Avionics bay, cargo compartment and lavatories
- C.
The galleys
- D.
All of the above
Correct Answer
B. Avionics bay, cargo compartment and lavatoriesExplanation
Smoke detection systems are installed in various critical areas of an aircraft, including the avionics bay, cargo compartment, and lavatories. This strategic placement is essential for early detection of smoke, minimizing the risk of fire-related incidents. In the avionics bay, detection is crucial to safeguard electronic systems, while the cargo compartment system helps monitor the storage of luggage and freight. Additionally, smoke detection in lavatories ensures swift response to any potential fire hazards in restroom facilities.Rate this question:

With “AVNCS SMOKE” warning activated the amber “SMOKE” light illuminates associated with the
- A.
BUS TIE push button
- B.
GEN 1 push button
- C.
GEN 1 LINE push button
- D.
APU master warning light
Correct Answer
C. GEN 1 LINE push buttonExplanation
When the "AVNCS SMOKE" warning is activated, the amber "SMOKE" light illuminates associated with the GEN 1 LINE push button. This suggests that there may be smoke or a potential fire in the electrical system related to the GEN 1 LINE. The other options, such as the BUS TIE push button, GEN 1 push button, and APU master warning light, are not directly associated with the "AVNCS SMOKE" warning.Rate this question:

The avionics bay smoke detector is located in the
- A.
Avionics bay
- B.
Ventilation extract duct
- C.
Skin heat exchanger
- D.
Cargo compartment
Correct Answer
B. Ventilation extract ductExplanation
The avionics bay smoke detector is located in the ventilation extract duct. This is because the ventilation extract duct is responsible for removing air from the avionics bay, ensuring proper ventilation. By placing the smoke detector in this duct, any smoke or fire within the avionics bay can be detected early on, allowing for immediate action to be taken to prevent further damage or potential hazards.Rate this question:

With the BLOWER + EXTRAC push buttons in OVRD the ventilation gets air from the
- A.
Inlet valve
- B.
Skin heat exchanger by-pass valve
- C.
Air conditioning inlet valve
- D.
Avionics
Correct Answer
C. Air conditioning inlet valveExplanation
When the BLOWER + EXTRAC push buttons are activated in OVRD (override) mode, the ventilation system is configured to receive air from the air conditioning inlet valve. This means that the air for ventilation is being sourced from the air conditioning system rather than other possible sources such as the inlet valve, skin heat exchanger bypass valve, or avionics.Rate this question:

Avionic smoke warning is inhibited during take-off from
- A.
80 kts to lift-off
- B.
80 kts to 1500 ft
- C.
Not inhibited
- D.
1500ft to lift off
Correct Answer
B. 80 kts to 1500 ftExplanation
During take-off, the avionic smoke warning is inhibited from 80 knots (kts) to 1500 feet. This means that if there is any smoke detected in the avionics system during this period, the warning system will not activate. Once the aircraft reaches a speed of 80 kts during take-off, the smoke warning system is disabled until it reaches an altitude of 1500 feet. This is done to prevent false alarms or distractions during the critical phase of take-off.Rate this question:

- 6.
Lavatory smoke detectors are situated in each lavatory air extraction duct?
- A.
True
- B.
False
- C.
Only in some aircraft.
- D.
None of the above.
Correct Answer
A. TrueExplanation
Lavatory smoke detectors are indeed situated in each lavatory air extraction duct. This is done to ensure the early detection of smoke or fire in the lavatory area, allowing for prompt action to be taken to prevent any potential accidents or emergencies. By having smoke detectors in these ducts, any smoke or fire can be quickly detected and appropriate measures can be taken to ensure the safety of the passengers and crew onboard the aircraft.Rate this question:

At activation of “LAVATORY SMOKE” warning the fire extinguishing system is automatically discharged
- A.
True
- B.
False
- C.
Only in emergency
- D.
All the time
Correct Answer
B. FalseExplanation
The statement "At activation of 'LAVATORY SMOKE' warning the fire extinguishing system is automatically discharged" is false. The fire extinguishing system is not automatically discharged when the "LAVATORY SMOKE" warning is activated.Rate this question:

Lavatory smoke detectors send warnings to
- A.
ECAM and Nose interphone panel
- B.
ECAM and CIDS
- C.
ECAM, CIDS and Nose interphone panel
- D.
Nose interphone panel
Correct Answer
B. ECAM and CIDSExplanation
Lavatory smoke detectors send warnings to ECAM (Electronic Centralized Aircraft Monitoring) and CIDS (Cabin Intercommunication Data System). ECAM is responsible for monitoring and displaying various aircraft systems, including smoke detection. CIDS is a communication system that allows crew members to communicate with each other and receive important information. Therefore, both ECAM and CIDS receive warnings from lavatory smoke detectors to ensure prompt action can be taken in case of a fire or smoke in the lavatory.Rate this question:

Smoke detection in FWD and AFT cargo compartment is consists of
- A.
2 smoke detectors and a SDCU
- B.
2 smoke detectors in FWD Bay, 4 detectors in AFT Bay and SDCU
- C.
4 smoke detectors in each bay and a SDCU
- D.
4 smoke detectors in AFT and SDCU
Correct Answer
B. 2 smoke detectors in FWD Bay, 4 detectors in AFT Bay and SDCUExplanation
The correct answer is 2 smoke detectors in the FWD Bay, 4 detectors in the AFT Bay, and an SDCU. This means that there are two smoke detectors in the forward cargo compartment and four smoke detectors in the aft cargo compartment. These detectors are responsible for detecting any smoke or fire in their respective compartments. Additionally, there is an SDCU (Smoke Detection Control Unit) that receives signals from the smoke detectors and processes them to activate the appropriate warnings or alerts in the aircraft's systems.Rate this question:

Air conditioning smoke warning is activated if smoke is detected in the
- A.
Air conditioning duct
- B.
Hot air manifold
- C.
Pack outlet ducts
- D.
No warning system is installed
Correct Answer
D. No warning system is installedExplanation
The correct answer is "no warning system is installed." This means that if there is no warning system in place, then the air conditioning smoke warning will be activated. In other words, if there is no mechanism or device to detect smoke in the air conditioning system, there will be a warning to indicate the absence of such a system.Rate this question:

In case of cargo compartment smoke warning, the agent bottle if discharged should be empty in less than
- A.
10 seconds
- B.
3 minutes
- C.
1 minute
- D.
30 seconds
Correct Answer
C. 1 minuteExplanation
The correct answer is 1 minute because in case of a cargo compartment smoke warning, it is crucial for the agent bottle to be discharged quickly in order to suppress the fire and prevent further damage. A discharge time of 1 minute ensures that the agent is released rapidly enough to effectively combat the smoke and fire in the cargo compartment. A longer discharge time could result in the fire spreading and causing more harm, while a shorter discharge time may not provide sufficient agent to extinguish the fire completely.Rate this question:

When pressing the CARGO SMOKE Test push button for at least 3 seconds, the smoke detectors are tested by SDCU, the RED smoke light comes on twice associated with ECAM and the isolation valves close?
- A.
True
- B.
False
- C.
Remain in its current position
- D.
Sometimes
Correct Answer
A. TrueExplanation
When the CARGO SMOKE Test push button is pressed for at least 3 seconds, the smoke detectors are tested by the Smoke Detection Control Unit (SDCU). This test causes the RED smoke light to come on twice, which is associated with the Electronic Centralized Aircraft Monitoring (ECAM) system. Additionally, the isolation valves close during this test. Therefore, the statement is true.Rate this question:
