How does the construction of the radome minimize lightening strike damage?
What is it constructed of?
It contains conductors.
It is constructed of fiberglass honeycomb.
Will there be any warning to the crew if there is improper main door and baggage door seal pressures?
On aircraft having ASC 439 incorporated, a door seal warning system is installed.
What keeps the main door closed?
6 sliding bayonets mechanically linked to the internal and external primary locking handles.
One bayonet activates the pressurization, and others control circuits within the hydraulic system and the “cabin doors” warning light in the cockpit.
Regarding the air stair door, how is proper bayonet seating ascertained?
By a triangular pattern of orange dot.
If orange dots are not visible, it is possible that the dot has worn off or that it is obscured by lubricant, etc. The orange dot pattern is painted over a notch on the bayonet. If the notch is visible, the bayonet is extended properly into its receptacle.
How many main entrance door lock switches are on the air stair door?
What are they for?
3
They are utilized to deactivate the auxiliary pump after the door is closed. The circuit is broken as the door is locked by the sliding bayonets physically actuating the doorlock switches.
Where does power for the control system of the airstair door come from?
By the essential DC bus through the DOOR CONT WARN circuit breaker located in the copilot’s overhead circuit breaker panel.
How do you close the door from outside the aircraft?
The external (guarded) battery switch is used to power the essential DC bus which will allow the OUTSIDE DOOR SWITCH to close the main door. CAUTION: After door is closed and locked, the external battery switch must be placed OFF to prevent a continuous drain on the battery.
On SNs 1156 and subsequent the essential DC bus is powered at the same time the outside door switch is activated so there is no need to use the outside battery switch.
What indications will there be if the external battery switch is left on?
Internal:
Blue EXT BATT SWITCH ON CAS message.
EXT BATT SW capsule on the overhead annunciator panel illuminated.
External:
Bottom beacon light will be on.
What keeps the baggage door closed?
4 Bayonets.
One controls the door sealing mechanism, and another controls the micro switch for the CABIN DOORS message.
How is the space between the panels on the fixed windows kept defogged?
By a desiccator system.
Regarding the wing tank design, how is corrosion prevented?
The tanks are over coated with polyurethane.
What is the output of each of the engine driven alternators?
115 VAC, 3 Phase, 30 KVA.
It is variable frequency (varies with engine power).
Therefore, it is sent to Variable Speed Constant Frequency (VSCF) converters (2) located in the aft compartment so the power can be stabilized and regulated.
The power to the converters is then rectified to DC (270 VDC POR).
Then it is converted back to controlled AC (115 VAC, 400 Hz, 3 Phase, 23 KVA).
There is also DC output from the converters (28 VDC, 250 Amps).
What engines are installed on the G IV?
2 Rolls Royce Tay 611-8 engines.
They are twin spool, axial flow bypass turbofans.
Regarding the aircraft engines, what does “Tay” mean, and why was it chosen for the name of the powerplant?
The River Tay is the longest river in Scotland and the seventh longest in the United Kingdom.
The use of river names (Trent, Nene, Avon, Tay, Conway, Spey, etc.) was introduced with the earliest Rolls jet engines to reflect their nature: a steady flow of power rather than the pulses of a piston engine.
Roll-Royce named their piston engines after birds if prey (e.g. Merlin, Peregrine, Kestrel, Vulture, and Buzzard).
What is the guaranteed minimum thrust rating of the main engines?
The Rolls-Royce Tay 611-8 engines have a guaranteed minimum thrust rating of:
13,850 lbs.
(ISA, Sea Level, Static)
What APU is installed on the G IV?
1) The Honeywell GTCP36-100[G]
- OR -
2) The Honeywell GTCP36-150[G] on some later air craft (ASC 465)
(The “G” simply stands for “Gulfstream”)
What are the hydraulic systems on the G IV?
1) Combined - powered by the left engine hydraulic pump.
2) Flight - powered by the right engine hydraulic pump (remember “flight is right”).
3) Utility - (PTU).
4) Auxiliary.
What conditions must be met for the utility pump to operate automatically when it is armed?
1) Combined system pressure less than 800 psi.
2) Flight system pressure more than 2000 psi.
3) Flight system fluid temp less than 220 degrees Fahrenheit.
4) Combined fluid is available.
Also, if flight system pressure falls below 1730 psi, the priority valve will close, causing utility pressure to go to zero. Placing the utility pump switch to ON will not restore the utility system.
How can the brake system be controlled from the cockpit?
Electrically or Hydraulically
- -The Brake by Wire (BBW) system uses an electrical signal to meter brake pressure.
- -The Hydromechanical Analog Brake (HMAB) system uses a hydraulic signal to meter brake pressure.
How is hydraulic power supplied to the brake system?
By the combined, utility or auxiliary system for both BBW and HMAB systems.
What controls the hydraulic stall barrier operation?
Angle of Attack inputs
What systems use bleed air?
Remember "TEA-PADS & Water" T = TAT Probe Aspirator. E = Engine Starter System. A = Air Conditioning (ECS Packs). P = Pressurization (ECS Packs). A = Anti-Ice (Cowl & Wing). D = Door Seal Systems. S = Servo Control Air. Water = Cabin Water System Pressure.
What engine stages provide bleed air?
7th or when needed 12th stage.
How are the cabin windows defogged?
By desiccant filters.
Where do the engine fire detection sensors monitor the engine temperatures?
They monitor the engine exterior temps in engine fire zone one, which comprises:
- Compressor,
- Combustion, and
- Turbine sections
How is engine fire extinguishing accomplished?
Through a two-shot, electrically fired chlorotrifluorobromomethane (CF3Br) system, consisting of two single-shot containers installed in the tail compartment.
How many pitot systems are on the aircraft?
Where are their sources or pitot tubes located?
3 Independent Systems
- 2 Primary: Pilot & Copilot.
- 1 Standby.
Pitot Locations:
- Pilot and Copilot: On top of the nose, forward of the windshield.
- Standby: Left side of nose below AOA probe.
How many static systems are on the aircraft?
Where are the static sources located?
4 Independent Systems
- 2 Primary: Pilot & Copilot.
- 1 Standby: Standby Altimeter and Airspeed Indicators.
- 4th System: Used by the cabin differential indicator on the overhead panel.
Static Sources:
- Each system has 2 sources (one on each side).
- Primary systems use upper ports, others use lower.
What type of capability does the autopilot provide?
The A/P uses 2 flight guidance computers to provide fail-operational capability.

FMS Winds
PPOS to 200 NM = 100% Sensed
200 NM to 400 NM = 50% Sensed / 50% Entered
400 NM & Beyond = 20% Sensed / 80% Entered
Vref Rule of Thumb
First, find aircraft weight.
(PROGRAM page 2 or PERF INITIAL page 5)
Example: 55,000 Pounds Put a 1 on the left and divide by 1000: - 155 (Vref for flaps 0) Subtract 10: - 145 (Vref for flaps 10) Subtract 5: - 140 (Vref for flaps 20) Subtract 5: - 135 (Vref for flaps 39)
Target Approach Speed = Vref + 10.
The closer to sea level, the more accurate this rule of thumb will be.

Approach Idle
Low Range (48%): When any of the following occurs: 1) Nutcracker in a ground mode, 2) Wheel spin-up greater than 65 mph (57 Kts), or 3) Flaps less than 22 degrees
High Range (67% HP):
When:
1) In flight, and
2) Flaps greater than 22 degrees
Autospeeds On Takeoff
- V2 until V2+10.
- V2+10 until flap change.
- 200 until vertical mode change.
- Then via PERF INIT climb schedule.
Autospeeds On Descent
- Above 10,000 = PERF INIT climb schedule.
- Below 10,000 = 240 (240 will be displayed if 250/10,000 is programmed).
During the arrival phase of flight, when will the autospeeds change from cruise speed to 200?
15 Nautical Miles (Track Miles) From The MAP (or runway).
Should you program “Direct To” anything in the FMS while still on the ground (i.e. on T/O tower clears you direct to a VOR in your flight plan)?
Why, or why not?
No.
You will lose all of your PERF data including all of your T/O numbers.
What is a dead-spot in the rheostats known as?
A Non-Engineered Dead Spot (NEDS).
Where can you find a list of items powered by the E-Batts?
QRH Page EA-26
Remember:
- Unlucky number = 13.
- Remember, if you are down to E-Batts, you are really, really unlucky (unlucky X 2: 13 X 2).
What items are powered by the E-Batts?
?
What temperatures will trigger the battery cooling fan?
On at 90 degrees Fahrenheit.
Off at 75 degrees Fahrenheit.
What is the AUX power priority?
1) APU
2) AC
3) DC
What power sources can start the APU?
- External DC (not external AC).
- Main batteries.
How many fans do the converters have?
5 Each
What type of power does the SEPS produce?
SEPS, HMG, or ABEX
- AC: 115 Volt 3 Phase AC at 5 KVA.
- DC: 28V, 50 Amps.
HMG - AC - TRU - DC
HMG - DC - E-Inv - AC
(This was done this way in order to produce predictable, stable electric power)
Powers only the ESS AC & ESS DC busses.
What exactly is powered by the SEPS?
See page EA-4 in the QRH
- “All essential AC and DC bus powered equipment…”

Where can you find a list of items powered (electrically) by each different circuit or bus?
QRH page S-13 and following
Remember, if you have to go back to the Blue Supplemental QRH section, you are having bad luck - hence, page # is 13
What does it mean if the ESS DC Bus AUTO, LEFT MAIN and BATT switch capsules are illuminated without the BATT 1 and BATT 2 switches illuminated or the BATT ON BUS message illuminated?
See QRH page EA-21
- The K20/K22 relay experienced a failure of one of the two relay-poles. Report for maintenance action.
What values on the EPMP for AC Volts, Freq, and DC Volts will not trigger the out-of-limit range markings (red bar)?
AC Voltmeter: 100-125 Volts = No Red Bar.
Frequency: 380-420 Hz = No Red Bar.
DC Voltmeter: 26.0-30.9 VDC = No Red Bar.

How many CAS messages can be displayed at one time?
23
What battery connects to the ground service bus?
Whenever the Ground Service Switch is selected ON the Ground Service Bus receives it’s power from BATT #2.
When would you expect to see a Battery On Bus indication?
Remember “EAA”
E = ESS DC Bus powered by main batteries (manually or automatically).
A = APU Start.
A = AUX Pump ON (operating).
When the Emergency Power System is armed, when will the E-BATTS activate?
3 Conditions Will Turn On The E-BATTS: (Remember "GEM") G = G load of 2.5 or more, E = ESS DC Bus loss of power (less than 20 volts), M = Manually turning them on.
Where is the Remote Power Supply (RPS) located, and what does it power?
Location = Right Avionics Bay.
It powers the EPMP switchlight, digit, and out-of-limit indicators.
External AC is capable of powering what busses?
With an external AC Power supply connected and operating, selecting the AUX Power switch and selecting at least one BATT Switch ON the AC Buses will be energized. The TRU will then be activated to power the DC Buses.
Also, battery charging is possible with External AC only (not with External DC).

When armed, what will cause the Utility Pump to turn ON automatically?
Combined System failure (Amber CMB HYD FAIL CAS message) or combined system pressure falling to less than 800 psi.
Also, the Flight Hydraulic system will have to have:
1) At least 2000 psi, and
2) 220 degrees F or less fluid temp.
And, the Combined reservoir will have to have at least 1 gallon of hydraulic fluid in it.
