A
2%
2
Q
How is automatic refueling controlled?
A
Via Standby Multifunction Controller (SMC) in the cockpit or refuel panel located at fueling station.
3
Q
How many boost pumps does the G650 have and where are they located?
A
There are four (4) identical and interchangeable fuel boost pumps in the main wheel wells attached to the aft portion of each hopper. One (1) Main powered by Essential DC and One (1) Alternate powered by the Main DC bus in each tank powered by its respective side (L & R).
4
Q
When does the “Fuel Crossflow Valve Open” message change to amber?
A
After five (5) minutes.
5
Q
What’s the warning associated with the use of the crossflow valve?
A
Always OPEN the crossflow valve BEFORE turning OFF both boost pumps on one side. Without boosted pressure above 20,000’ Gulfstream says the engine will run erratically and flameout. This is also true in the reverse scenario when you go to close the crossflow valve, so make sure to turn the pumps back on BEFORE CLOSING the valve.
6
Q
What happens when the FUEL RETURN switch is selected to AUTO?
A
The OFF caption extinguishes and the system allows heated fuel into the tanks when fuel tank temperature is approximately 0C or colder. When tank temperatures warm to approximately +10C, heated fuel stops flowing to the tanks.
7
Q
When will the the heated fuel return system be inhibited?

81
When will the PLI appear?
At 0.75 AOA
82
At what AOA does the stick shaker activate?
0.94 AOA
83
What has to happen in order to get to Direct Control Law Mode?

Control Law behavior in Backup Mode is very similar to Alternate Mode (Gain is the same), but there is
-No roll assist from the mid spoilers,
-No speedbrake or ground spoiler capability, and the
-Yaw damper effectiveness is significantly reduced (IRU #3 must be operative).
-Pitch trim is only available via the Backup Pitch trim switch on the center pedestal, and the trim rate is reduced to 1/3 the normal rate.
-No yaw trim or stick shaker available in Backup Mode.
If Direct Mode or Backup Mode becomes the active control mode, the aircraft remains in that control state until power is cycled, even if a single FCC channel becomes available.
87
What has to happen for the Control Law mode to be changed to Backup?
-A complete loss of data from the FCC’s.
88
Both the HA’s and EBHA’s operate in one of the following states: Active or Damped Bypass. Describe Damped Bypass.
In Damped Bypass state, the affected actuator is in a damped condition, meaning that hydraulic pressure is trapped within the actuator to suppress control surface flutter in flight. On flight controls with dual actuators (ailerons, elevator, and rudder), the operational actuator will command surface movement, and the failed actuator (now in a damped condition) will passively follow the working actuator.

-Two red W’s, and
-One red CAS message.
Additionally, you get a fire bell on ground.
136
Describe the equipment overheat detection system.
A number of thermal switches are installed in the aircraft interior to monitor temperature levels. They utilize two preset temperatures: 150°F and 250°F, depending on location and type of equipment monitored. Switches set at trip point of 150°F generate an amber CAS message when that temperature is reached and switches set at trip point of 250°F generate a red CAS message (generally amber for electrical and red for bleed air).
137
What are the preset temperatures for the thermal switches that monitor interior temperature levels?
150°F and 250°F, depending on location and type of equipment monitored.
Switches set at trip point of 150°F generate an amber CAS message.
Switches set at trip point of 250°F generate a red CAS message
(generally amber for electrical and red for bleed air).
