Systems Flashcards
Eng fire protection and powered how?
ENG ovht/fire det - battery bus
Eng fire ext - HOT BAT BUS
ENG OVHT/FIRE DETECTION
each engine - 2 loops
Lower limit - OVHT
Higher limit - FIRE
BOth loop must sense condition
Remains - temp drop
Fault monitoring circuit?
one loop fails with OVHT DET switch in NORMAL, that loop = auto deselected - remaining loop function as single loop.
FD indication of single loop failure?
NO
Both loops fail on engine - FAULT light on and system inop.
Only Loop A or B selected?
Single loop system
Non selected loop - not monitored
Selected loop fails - FAULT light
APU fire protection?
fire detection - battery bus
fire extinguishing - hot batt bus
Detection?
singe loop
Fault monitoring system
loop fails, the APU DET INOP light illuminates -
Main wheel well fire detection powered?
AC TRANSFER BUS 2 and BATT bus
single loop
Cargo compartment smoke detection?
DC Bus 1 and DC Bus 2
Cargo fire suppression?
HOT BAT BUS
Total loop cargo compartment?
dual loop
How many needs to detect smoke?
both
Detector failure?
Sys manually converted to single loop with DETECT SELECT switch.
Power failure of one loop?
Auto converts to single loop
YR017 - YR024 Fire suppression system?
single bottle
Total discharge of bottle
75min suppression
60 flight time to land
15min GA, land, unload pax
30s light DISCH to illuminate
YR027-YV394
two bottles
1st bottle total discharge 60min protection
2nd bottle metered to discharge reduced flow.
195min
180 to land, 15min GA, land, unload pax.
Discharge 2nd bottled may be disabled if system disarmed.
Landing - 1st bottle discharged and system remains armed - 2nd bottle discharge inhibited.
Lav fire protetion consist of?
smoke detection
fire extinguishing - heat activated
Name of system and monitors for?

for smoke
Smoke detected?
aural warning
red status indicator light on LAV smoke detector panel illuninates
Fire extinguishing system location?
Beneath sink area in Lav.
Fire detected?
auto operation
FD no indication.
FAULT INOP TEST?
2 x MC
OVHT/DET light on system annunc
FAULT light
APU DET INOP
OVHT/FIRE Test Detection??
