What is the GCU, and what does it do?
The generator control unit (GCU)
automatically switches the generator
from starter to generator mode
- GCU acts as a voltage regulator
when in generator mode
- GCU controls generator through the
generator line contactor (GLC)
- GCU protects generator from reverse
current flow
- 32.5 volts or greater will cause GCU
to open the GLC due to over-voltage
Why are the generators 28 volts?
To charge the 24 volt batteries when operating
How is electricity distributed in the 900XP?
Through the electrical buses
How are the batteries’ voltages tested? Do you need to have the batteries on?
Through the volt-meter on the overhead panel - batteries do not need to be on
Where does the GPU plug in?
The GPU plugs in the right rear fuselage
What are some GPU limitations?

Unmarked pointer indicates cabin rate of change
Red and white pointer indicates differential pressure
What is the cabin pressure and psi differential at FL410?
Cabin pressure of 7,500 feet, psi differential of 8.55 psi
How do we control cabin pressure?
By controlling the amount of air we let out of the cabin
What scenarios warrant oxygen masks on?
Electrical fire or smoke, fuselage fire or smoke, smoke from air conditioning duct, depressurization
What is the maximum psi differential?
8.55 psi
What is the overpressure psi differential?
8.6 - 8.8 psi
What is the maximum negative psi differential?
-0.5 psi
What is the limitation regarding engine and APU bleed air?
Simulataneous operation of APU bleed air and engine bleed air limited to one minute during changeover
What keeps outflow valves open on the ground?
Venturi in forward closet
When does the Cabin High annunciator illuminate?
Normal: 9,300 ± 300 feet
High-Datum Mode: 14,000 ± 300 feet
When a fault is fixed, does the annunciator extinguish?
Yes, annunciators extinguish when the condition causing the annunciator is removed
What bus powers the Master Warning System?
The PE bus
What are 3 ways the aircraft talks to us? Give examples of each
Visual - annunciators
Audible - fire bells
Tactile - stick shaker
How can we test all annunciators at maximum intensity?
The ANNUN push-button on the overhead test panel
What are the hydraulic accumulators pre-charge pressure?
Main Accumulator: 1000 psi
Wheel Brake Accumulator: 1000 psi
Thrust Reverser Pressure: 1500 psi
What is normal hydraulic system pressure?
3000 psi
What is the hydraulic overpressure psi? What happens if that is reached?
4000 psi - hydraulic fluid returned to the reservoir
What are the 3 fuel pump types? How do each work?
Jet pumps, boost pumps, engine-driven pumps
Jet pumps: no moving parts, motive flow driven
Boost pumps: electrically driven, “suction” fuel to lowest point of fuel tank and send fuel to engine-driven fuel pumps
Engine-driven pumps: run off the accessory case, atomize the fuel, engine will not function if they do not function
Where are the electric fuel boost pumps located?
The #1 fuel compartments (lowest point of the wing fuel tanks)
What is the maximum fuel imbalance?
500 lbs
What must be working in order for ventral fuel tank transfer?
The electric boost pumps
When is the engine APR armed?
Takeoff
What are stators and rotors?
Stators: static fins
Rotors: rotating fins
What is a spool? What spools are on the TFE731-50R?
A compressor with a power turbine - there are 2, N1 (Low Pressure) and N2 (High Pressure)
What is an axial flow compressor?
Mounted on a common shaft, located on the Low Pressure Spool N1, increases air pressure without directly increasing velocity of the air significantly
What is a centrifugal compressor?
Mounted on a concentric shaft, located on the High Pressure Spool N2, consists of an impeller, diffuser, and compressor manifold
What is a CZI? MPI?
Compressor Zone Inspection: in-depth and costly inspection, requires complete disassembly of the engine - every 6,000 hours
Major Periodic Inspection: primarily looks at the turbine section and areas of the hot section - every 3,000 hours

When does APR activate? What is a limitation of the system?
Activates when an uncommanded split in N2 occurs of 15% or more; may not produce more engine power than what is available/exceed engine limitations
Where and what is mounted on the accessory case?
Mounted on the High Pressure spool (N2), contains starter-generator, hydraulic pump, alternator, fuel pump, fuel control unit, oil pump
What ice detection systems does the Hawker have?
Rotary cutter ice detector and ice detection light
What does an ANTICE LO QTY annunciator indicate? How much protection time in minutes is left?
Indicates 1/4 tank of TKS fluid remaining, ~30 minutes of protection left
What are 3 types of wing anti-ice and de-ice systems?
Weeping Wing/TKS fluid: uses fluid for anti-ice protection on leading edges
Inflatable Boots: leading edge inflatable devices that de-ices any buildup of ice on the surface (typically leading edge)
Hot Wing: uses bleed air help prevent the buildup of ice on leading edges (anti-ice)
What does an ANTICE LO PRESS annunciator indicate?
Indicates that there is a low system pressure of the TKS fluid system with the pump on

Left Alternator:
- Left windscreen
- Right sidescreen
- Left pitot/stall vane

How can we make fire extinguisher bottles go to either engine?
Fire extinguisher bottles can go to either engine: depends on the switch you activate (Engine 1 or Engine 2)
