Fire and Overheat Protection Flashcards
Which component does not have fire protection
Wheel Well
Which component does not have fire detection
Pneumatic ducts
Which components have overheat detection
Engine, Pneumatic ducts
What indicates a fault in one of the fire detector loops
EICAS STATUS message
What kind of fire detector system is used in the cargo compartment
Dual loop smoke detectors
What occurs automatically when an APU fire detected on the ground
The APU shuts down
Where is a fault in the fire detector loops displayed
EICAS status message
Which of the following occurs when a single fault is detected on an engine fire detection loop during test
System reconfigures for single detector operation
What message is displayed when faults are detected on both loops in an engine fire detection system
FIRE/OVHT SYSTEM advisory
Fault monitoring of the cargo smoke detectors only occurs during a system test
True
What is used to induce airflow through the cargo smoke detector
Fans
What warning indications are tested during a fire detection system test
Fire warning bell, discrete lights and master warning lights
Which detectors are checked when the ENG/APU/CARGO FIRE OVHT TEST switch is pushed
Engines, Cargo and APU
When will the fire warning extinguish in the Engine Fire Switch
When the fire signal no longer exists
What does pulling the Engine Fire Switch do
Closes associated engine and spar valves, trips the generator field relay and breaker, arms the fire extinguisher agent switch, closes the engine bleed air valves, closes hydraulic fluid valves to the engine hydraulic pump and silences the fire waning bell.
What should you do if the Engine Fire Switch cannot be pulled out during an engine fire
Push the Fire Override Switch then pull the handle
What is accomplished by rotating the Engine Fire Switch to the stop
Discharge selected fire extinguisher into respective engine nacelle
When will the APU BTL DISH light be illuminated
When the APU fire extinguisher has been discharged.
Can both fire bottles be discharged into either engine
Yes
How long should you wait before discharging the second fire extinguisher bottle into an engine that continues to have an illuminated fire warning light
30 seconds
Where is the APU remote control panel located
Nose wheel strut
When an APU fire is detected, the APU Fire Warning Horn is silenced by pushing the nose strut mounted APU shutdown switch or extinguishing the fire.
True
What does pushing the nose strut mounted APU Shutdown Switch do
Shutdown the APU, Silence the APU Fire Warning Horn
When does the APU Fire Warning Light extinguish
When the fire signal no longer exists
What happens to an operating APU when the Fire Switch is pulled out
It will shut down immediately
After pulling out the APU Fire Switch, the APU fire bottle discharges when the APU Fire Switch is rotated in either direction
True
When is the Fire Bell & Warning Light inhibited
During T.0. from nose gear extension to 400 feet or 20 sec.
When will the AFT Cargo Fire Warning Lights go out
When smoke is no longer detected
What does pushing the FWD Cargo Compartment Armed Switch do on 767-300 Passenger
Arms the fire extinguisher bottles, silences the fire warning bell, turns off both recirculation fans and shuts down Nitrogen System
What results when faults are detected on both loops in an engine fire detection system
Fire Warning
All fire protection systems are powered by
Hot battery bus
If a fire is detected in the APU compartment
The fire warning signal initiates an automatic shutdown
Pulling the APU FIRE switch accomplishes what
Closes the APU fuel shutoff valve, Closes the APU bleed air valve, Trips the APU generator field relay
How many fire bottles are installed for the engine fire control
2
How many fire bottles are installed in the cargo fire protection system
3
Fire suppression in the main deck cargo compartment is accomplished by pushing the MAIN ARMED switch followed by the DEPR/DISCH switch. These actions attempt to extinguish the fire
With a gradual depressurization of the aircraft
Fire suppression in the main deck cargo compartment is accomplished by
Shutting off the supply of air to the compartment
What is the result of both fire/overheat detect loops having failed on the left engine
No fire detection on the left engine
A cargo fire warning occurs when either smoke detector senses the presence of smoke
False
Does pulling the APU fire warning switch silence the fire bell
Yes
What should you do if the engine fire warning switch cannot be pulled during an engine fire
Push the override switch while pulling the Fire Warning Switch
What occurs when a single fault is detected on an engine fire detection loop during test
System configures to single loop
How can you silence the fire bell
Push either master CAUTION/WARNING reset switch or pull the fire switch
What happens when you push the DEPR/DISCH Switch with the MAIN deck fire switch ARMED
Initiates aircraft depressurization
