Fire Protection Flashcards
How is the engine overheat & fire detection system normally operated
?
How is an ENG OVERHEAT condition indicated
MASTER CAUTION, OVHT/DET annunciator & associated ENG OVERHEAT lights illuminate
What does an illuminated fire control panel FAULT light indicate when no fire test is being performed
Both loops on one engine have failed in the dual loop position (NORMAL) or selected single loop on an engine has failed
The FAULT light illuminates on the engine fire control panel with no fire test being performed. Are there any other lights or indications
No. No additional indications are triggered with a FAULT light on
What are the power sources for engine fire detection & extinguishing
Detection- Battery bus; extinguishing- Hot Battery bus
Which statement regarding the engine fire extinguisher bottles is correct
Two bottles available for either engine
How is the squib on an engine fire extinguisher bottle armed
Pulling the fire switch arms the squibs
How are the engine fire warning switches ( red handles) released
Released by overheat, fire or manually
How is an engine fire extinguisher bottle discharged
Pull illuminated fire warning switch up, rotate either to the left or right
What does an illuminated BOTTLE DISCHARGED light indicate
Extinguisher bottle has discharged
What is the function of the OVHT/FIRE position of the FIRE TEST switch(Normal AC power on the generator buses)
Tests all aircraft fire and overheat loops
During an extinguisher system test (squib test) what does an engine fire extinguisher illuminated green EXT TEST light indicate
Discharge circuit test is normal for respective extinguisher circuit
Which statement describes the APU fire detection system
Single loop system for fire or fault detection
What does an illuminated APU DET INOP light indicate when no fire warning test is being performed
Failure in the APU fire detector loop
What occurs when an APU fire condition is detected(cockpit only)
APU fire warning & master FIRE warning lights illuminate and fire bell sounds in cockpit and APU shuts down
What are the initial indications of a fire at the APU Ground Control Panel (On The Ground)
Flashing Fire Warning light and intermittent horn
In the event of an APU fire warning, what occurs when a cockpit FIRE warning bell cut-out switch or the APU Ground Control Panel (GCP) HORN CUTOUT button is pressed
Cockpit fire bell and GCP horn are silenced, GCZp light illuminates steady
How is the APU extinguisher bottle discharged from APU Ground Control Panel
Pull fire control handle, then activate discharge switch
Which describes the WHEEL WELL fire warning system
No. 1 AC Transfer bus powers a single loop detector
How is a WHEEL WELL fire indicated
WHEEL WELL fire & master FiRE warning lights illuminate with steady fire bell
A smoke detection and fire suppression system is installed in the cargo compartment of the 500 aircraft
True
How is discharge of a lavatory fire extinguisher determined
Bottle nozzle tips change to an aluminum color
When the fire control panel test switch is placed to the FAULT/ INOP position, which lights should illuminate
Two MASTER CAUTION lights, the OVHt/DET annunciator, the FAULT light, and the APU DET/INOP light
During the FAULT/INOP test, the FAULT light does not come on but the APU DET INOP light does
?
The engine fault detection system has failed
?(apu)
The engine fire panel FAULT light illuminates during an overheat/fire test. This indicates
At least one engine has a faulty loop
On arrival at the aircraft you find the FAULT light illuminated prior to any system test. The loop selector switches are in the NORMAL position. Both fire warning loops on one engine have failed
True
Inflight with dual loop configuration selected, you observe the FAULT light illuminated on the fire warning panel. What has happened
Both loops on one engine have failed
Engine fire detection is powered from the
Battery bus
Engine and APU fire extinguishing is powered from the
Hot Battery bus
If a fire is detected in the APU, the APU shuts down, the fire bottle discharges, and the fire bell silences after the fire bottle is discharged automatically
False
The WHEEL WELL fire detection system is DC powered
False
In flight, what happens if a single engine fire detector loop fails during dual loop operation
The loop is automatically deselected and fire warning capability is not lost on that engine
The OVHT/DET annunciator and the MASTER CAUTION lights are illuminated( triggered by)
The APU DET INOP light or an engine OVERHEAT light
The Fire Control panel FAULT light illuminates
During the FAULT/INOP test
During the EXTINGUISHER TEST, what do the illuminated green lights on the Overheat/Fire protection panel indicate
The fire extinguisher discharge circuits are functional
When the lavatory smoke detectors are activated, the FIRE WARN, MASTER CAUTION, and fire annunciator lights illuminate, and the fire bell sounds on the flight deck
False
The cargo compartment smoke detector and fire suppression system must be verified to be serviced and operational before cargo can be carried in the cargo compartments
True
After activation of the cargo fire suppression system the aircraft must land at the nearest suitable airport within____minutes of the activation(500)
60 minutes
What are the possible flight deck indications for a wheel well fire
?
There is no fire extinguisher system for the wheel well area
True
There is no FAULT warning for a failure of the wheel well fire detector
True
The power to the fire extinguisher bottle squibs is provided by the
Hot Battery Bus
