an over-voltage of ___ or higher will cause the GCU (generator control unit) to automatically open the GLC
32.5
What does the GCU do
provide output stabilization and load equalization
automatically switches from starter mode to generator mode
in generator mode, it will act as a voltage regulator
controls the generator by directly controlling the GLC (generator line contactor)
provides reverse current flow protection
Why are our batteries 24v but our system is 28v
The voltage all together needs to be greater so that the batteries can charge off of the extra voltage
How is the electricity in the electric system distributed
busses
How do we test the volts for our battery
the battery pushbutton connects ammeters to batteries to show the charge rate of the batteries.
it is hot-wired to the battery so there is no need to turn anything on. just turn a knob so that we are looking at it specifically.
What should our battery amps be at for takeoff
needs to be below 20 amps
GPU (ground power unit)
standard 3 pin, 28 volt DC ground power receptacle located on right rear fuselage
what is the only thing that can run everything with engines off
GPU
What information does the cabin triple indicator give us
cabin altitude
differential pressure
rate of change
Cabin pressure at FL 410
7500
8.55 PSI
How do we control cabin pressure
pressurization is achieved by supplying bleed air into pressure vessel and controlling the outflow
Max cabin pressure differential
8.55
Max Negative Cabin Pressure
-.5
Max Cabin Over Pressure
8.6-8.8
What is the limitation with engine bleed air ad APU bleed
can both be on for no more than 1 minute
What keeps the outflow valves open on the ground
venturi
when will the cabin high annunciator go off
9300 +/- 300
high datum - 14000 +/- 300
what color is the cabin high annunciator
red - it will set the master warning lights off
Will an annunciator extinguish after it has alluminated
yes, if the reason it went off goes away
what bus powers the MWS system
PE
3 ways and examples the aircraft talks to us
visually - annucniators
Audibly - bells and chimes
Tactically - stick pusher/stick shaker
how do we test all annunciators to max intensity
annunciator test button
Fuel pump types
Jet pumps - 4 - no moving parts - just moves fuel through the inner tank parts
Boost pumps- 2 - moves ventral fuel - helps move fuel from tanks to engine
engine driven - 2 - automizes fuel - if it dies we die
Boost pump locations
1 in each wing
max fuel imbalance
500 pounds in between the wings
What must be working for ventral tank transfer
boost pumps
stator vs compressor
stationary - stationary
compressor - rotating (rotary)
Why do we put the APR in armed position
activates when uncommanded split in N2 occurs of 15% or more
spool
twin stool engine (N1 and N2) compressor and turbine connected on a single shaft - we have 2
Axial Flow
low pressure compressor - 4 rows or compressors (spin/move) 4 rows of stators (stationary)
CZI vs MPI inspections
CZI - every 6000 hours - much more in depth and costly - complete disassembly of engine - compressor zone inspection - confused with overhaul
MPI - every 3000 hours - looks primarily at turbine section - a lot like a hot section - major periodic inspection
both are more complex than what they are associated with
For maximum T/O thrust what is the N1, N2, ITT and time limit
N1- 100
N2 - 101
ITT - 1022
5 minutes
what is on the accessory case
oil pump, fuel pump, starter generator, alternator, fuel control unit, hydraulic pump
when do we get notified the TKS fluid is low
30 minutes remaining
Vibrometer explianed
an electrical pulse is sent thorugh a probe making it vibrate. as you fly ice collects making the probe heavier and the vibrations slower. As it slows it talks to th aircraft saying ice is forming
Our icing system
rotary ice cutter on the forward left fuselage as ice forms it is being cut off causing the rotation to slow due to the friction. As this friction grows and the turn slows it talks to the airplane letting it know ice is forming
TKS anti-ice system
TKS fluid is pumped out of the front of the wings and the horizontal stabilizer
it is pushed over the wing and elevator by wind going over the surfaces preventing from ice build up
Hot wings
hot bleed air from engine is pushed to the front, top, and bottom of wings warming the surface of the aircraft and melting/ preventing ice on the surface
WIng boots
inflatable boots on the front of wings that after ice has formed you will inflate to knock already formed ice off of the wing
when will you get anti-ice low pressure system
low system pressure with pump on
what do the alternators do for anti-ice
2 engine driven alternators heat the windscreens-sidescreens - stall vanes electrically
Alternator 1 heats
left windscreen, right sidescreen, left stall vane
Alternator 2 heats
Right windscreen, left sidescreen, right stall vane
what does the fire annunciator tell us
something is very hot - just because it goes off does not mean there IS a fire
how do we choose which side our extinguishers go to
by choosing shot 1 or 2 on the engine ext button for the engine that is having the overheat/fire alarm
what does shot 2 run off of
PS2
at does shot 1 run off of
PE
where are the fire extinguisher shots located
aft equipment bay
when would we have the emergency brakes on
when we attempt to brake and have no braking authority
how do we turn the emergency brakes on
pull the wheel lever back 1 notch
Hawker Anti-Skid
only provided during normal braking
called maxaret
fully mechanical
wheels must be moving
lift dump limitations
must be on the ground
flaps must be “selected” 45
where does the APU get its fuel from
left tank at .5 gallon an hour
What does the APY do
provides power and bleed air on ground and in flight
who monitors the APU
it monitors itself
what happens for APU fire
APU overheat detector go off
fire bell and annunciator go off
single shot fire extinguisher can be set off by pilots or after 5 seconds after APU auto-shutdown due to overheating it will not automatically go off
Master supply valve
allows oxygen into entire oxygen system
pilots need it open/passengers neet it open
emergency passenger supply valve
deploys passenger masks manually
Cabin oxygen
supplies passengers with oxygen
knob located behind pilots head
Barometric Valve
supplies masks and oxygen to passengers at cabin altitude of 14500+/- 500 ft
The emergency escape hatch is on the ____ side, _____ window
Right; fourth
to recieve external power, the ground power unit must be plugged in to the ground power receptacle on the
right rear fuselage
