How is the cabin protected from fire ?
4 Hand - held fire extinguishers ( 2 FWD and 2 AFT )
Can both engine fire extinguishing bottles be used for one engine if needed ?
Yes
How many fire extinguishing bottle shots do you have for the engine ?
2 , A & B. Both bottles can be used for one engine , or one bottle in each engine .
Pulling an engine fire handle causes what ?
Closes the respective engine fuel shutoff valve , closes the respective engine hydraulic shutoff valve , closes the respective engine bleed shutoff valve and closes the crossbleed valve
Does pulling an engine fire handle discharge the bottle ?
No
Will the fire handle work without power on the aircraft ?
Yes , Fire Extinguisher , Hydraulic SOV , and Fuel SOV , are on the HOT BATT BUS .
Describe the engine and APU fire detection system .
Engine and APU are monitored by two detector loops
What are the initial indications of an APU fire ?
Fire bell and master warning triple chime , red stripe in the APU EMER STOP button , APU FIRE EICAS message and 2 master warning lights
On the ground , the APU will shut down automatically _______ seconds after the fire condition is sensed .
10
Will the APU automatically shut down on the ground for a fire ?
10 seconds after APU fire detection and the APU EMER STOP button has NOT been pressed .
Will the APU automatically shutdown in flight for a fire ?
No
What happens when the APU EMER STOP button is pushed after a fire has been detected ?
a ) APU shuts off immediately without a 1 - minute cooldown , APU fuel shutoff valve ( SOV ) closes and APU FIRE EXTG button illuminates
b ) Red stripe bar is replaced by a white striped bar , indicating the APU has shut down .
What happens if the APU EMER STOP button is NOT pushed after a fire has been detected ?
After 1 minute the APU FIRE EXTG button illuminates and APU will automatically shut down after ten seconds on the ground
What does it take for the APU FIRE EXTINGUISHER light to illuminate ?
APU EMER STOP button has been pushed in when an APU fire has been detected , or 60 seconds after an APU fire has been detected and no pilot action has occurred
When does the red bar to illuminate on the APU EMER STOP button ?
APU fire is detected
What is the importance of pressing the APU EMER STOP button before the APU FIRE EXTINGUISHER button ?
With the APU running , it would act as a venturi and suck all the halon overboard and waste your only halon fire bottle
Pressing the APU FIRE EXTINGUISHER button causes what ?
APU fire bottle discharges , APU shuts down , and the APU fuel shutoff valve closes
Can the low - rate bottle be discharged before the 1 minute is up for the cargo compartment in flight ?
Yes , by pushing the associated extinguisher button again
How can the low - rate cargo compartment fire bottle be discharged if the aircraft is on the ground ?
Flight crew must push the cargo fire extinguisher button again Will the low - rate cargo fire extinguisher bottle discharge automatically on the ground after 1 minute ?
Will the low - rate cargo fire extinguisher bottle discharge automatically on the ground after 1 minute ?
No , the flight crew must push the cargo fire extinguisher button again .
Can cargo fire extinguishing be used if no smoke is detected ?
Yes
If NO smoke is detected , explain the logic for the CARGO FIRE EXTINGUISHER button in flight .
The extinguisher button must be pressed twice , first to arm the high rate bottle and second to discharge the high rate bottle . Then the low rate bottle is armed and will automatically fire after 60 seconds ( 2 pushes )
If NO smoke is detected , explain the logic for the CARGO FIRE EXTINGUISHER button on the ground .
The cargo fire extinguisher button must be pushed three times . First to arm the high rate bottle , then second to fire the high rate bottle and arm the low rate bottle . The third push fires the low rate bottle .
If smoke is detected , explain the logic for the CARGO FIRE EXTINGUISHER button on the ground .
The cargo fire extinguisher button must be pushed twice . First time the high rate bottle discharges immediately . Second push discharges the low rate bottle
If smoke is detected , explain the logic for the CARGO FIRE EXTINGUISHER button in flight .
Pushed once , this discharges the high rate bottle immediately . After 1 - minute the low rate discharges automatically .
How many fire extinguisher bottles are installed for the cargo compartments ?
2 , 1 high rate bottle and 1 low rate bottle
What is the difference between the low rate and high rate cargo fire extinguisher bottles ?
The high rate discharges immediately . The low rate protects the compartment for 75 minutes
How long does the low rate bottle protect the selected cargo compartment ?
75 minutes
Can one cargo fire extinguisher bottle be used for one cargo compartment and the other cargo fire extinguisher bottle for the other cargo compartment ?
No. Only one compartment may be selected ( FWD or AFT ) protected
How are the lavatories protected from fire ?
1 fire extinguisher bottle located in each waste container that automatically discharges when the temperature exceeds a certain limit
What are the indications that smoke is detected in either lavatory ?
LAV SMOKE EICAS and 2 master warning lights illuminate , aural alarm in the lavatory will sound and the detector light will illuminate and flashing orange on the respective flight attendant rainbow light bar illuminates
When the lavatory smoke detector is set off , will the flight deck know which lavatory it is ?
No. The generic EICAS LAV SMOKE message illuminates and the respective cabin rainbow light will show which lavatory it is
Which fire extinguisher bottles on the aircraft work automatically ?
Lavatory trash container [Show Less]
