GOS Flashcards
highest priority checklist
evacuation
highest chance for loss of life
What is a sign of incapacitation
if you ask a question twice with no response
AED location
aft overhead left
“will carry” hazmat
dry ice
bio substance category B
lithium batteries (with vaccines)
engine
Gen electric CF34-8E5
CF commercial fan
34 model number
8E5 embraer
Describe N1
single stage (big fan up front)
shaft through center
low pressure reaction turbine (4 stage at back)
Describe N2
10 stage axial flow compressor
powered by 2 stage high pressure reaction turbine
Cold section
N2 compressor forward
hot section
N2 compressor backward
annular combustion chamber
exciters and igniters
(like magnetos and spark plugs)
vgigv
variable geometry inlet guide veins
behind big fan
automatically adjust pitch (regulates engine airflow)
actuated by fuel pressure going into engine
what engine stage does bleed air come from
6 and 10
accessory gear box
air turbine starter (ATS)
powered by bleed air, arms overcome spring tension, starts spinning N2
integrated drive generator (IDG)
creates 3 phase AC
thrust reversers
cascading reversers
slides cowling back and redirects airflow
thrust reverser usage
lift up on trigger and pull back
locked until weight on wheels
2 settings, only ever use max
t/f
slats / flats move independently
false
they are synced
t/o flap settings
1, 2, 4
landing flap settings
3, 5, full
in flight APU will auto shut down for
overspeed, underspeed, fadec critical fault
FADEC info
3 total
only controls designated engine
dual channel (info in info out)
FADEC gone = engine gone
intake side of engine
T/F
in flight if the engine control is set to stop, the FADEC will shutdown the engine
false
engine will only shutdown with engine lever at idle
T/F
there is no mechanical connection between the thrust levers and the engine
True
uses rheostats
APU
hamilton sunstrand aps 2300
bleed air for:
AC
engine start
pressurization
what spots have zero icing protection
inboard slats (don’t produce enough lift comparatively)
tail (vibrations should shake off)
