Throttle servo & stop feather servo
In flight operation mode, what controls the blade pitch of the prop?
The propeller govenor
In response to the pilot’s inputs the propeller governor controls what aspect of flight?
RPM
What allows fuel to flow from the inboard aft & forward fuel tanks to the header tank?
Venturi effect

What does DEEC stand for?
Digital Electronic Engine Controller
What limits engine torque and exhaust gas temperature?
THE DEEC (by monitoring throttle position and fuel flow)
How many fuel tanks are there, and where are they located?
7 total:
3 in fuselage (fore, aft, header)
2 in each wing (outboard is gravity fed)
How does fuel get to the engine?
From header tank via 2x electric fuel pumps connected in parallel.
Operate independently for 20min with 10sec overlap on switchover.
Equipped with check valve to prevent reverse flow when 1 pump activated.
Where are the fuel system EPs?
3.28-3.32
Where is fuel system data contained?
VIT 1, 48, 50
When does the ignition unit deactivate?
When the starter is automatically deactivated (end of start cycle at 60% RPM)
How are numerical indicators displayed on the HUD?
Green if parameter within normal limits
Yellow to indicate caution
Red to indicate warning
Which VITs show comprehensive real-time engine and system parameter readouts on the HDD?
1, 46, 47, 65
Is SAS a closed loop?
Yes
Is SAS enabled all the time?
Yes, in all circumstances except extreme emergency
Where do you see the warnings for the flight control systems?
HDD heads down display
How does the prop control system, control turbo prop engine thrust?
Pitch and RPM
In flight op mode pitch control passes oil from the propeller governor to what?
The propeller
In flight op mode, the prop governor controls RPMs in response to what input?
Speed and throttle lever
The DEEC controls your fuel flow in response to what?
The Prop
What does negative torque sensing do?
It senses engine failure and partially feathers prop blade to provide relief through the DEEC
What does the speed lever set?
RPM
How do you know if you have a speed control failure?
You don’t get enough RPM, it would be inadequate
If you have an oil leak, would it impact your variable pitch prop?
Yes
What 3 things does the fuel system do?
Provides fuel to the engine
Monitors system parameters
Responds to control commands
What do the electric fuel pumps do?
Pumps fuel from the header tank to the engine
What controls the solenoid valves?
The RCM
How does a fuel flow sensor work?
It tracks the fuel used, by calculating the number minus the given fuel
Where does fuel jettison from?
The main dump valve is on the header tank return line, the backup valve is located on the return manifold
What are three ways you could get a low header tank pressure?
A leak
An open return manifold
A feeds failed closed
When can you turn hold modes off
Above 50kts
What heading hold control methods are there?
Control stick or HDD input
Default SAS, what axis does it work in?
All 3
Should you deactivate SAS?
Only in an extreme emergency
Airspeed preference mode, if it’s climbing or descending, what is the aircraft going to attempt to fly?
Airspeed has priority, nose down
Aileron tip stall active between??
5-9 degrees AOA
Autopilot sensor failure is talking about what?
EGIs failure
What parameters can you control in preprogram missions?
Airspeed Alt IFF Route of flight Payload AV transmitter
Does preprogram mode limit your AOA ability?
Yes
Emergency mission diamond waypoints are what colour
Red
You upload and op mission, where would you check it?
VIT 17
If an aircraft goes lost link while on an op mission, it will go to the emergency mission unless …
Lost link OK is selected for the leg its on
Where are the IFF antennas
Top and bottom of fusalarge
IFF mode two is for what?
Military air traffic
How do you get to the different IFF modes?
The tracker display
As per your SOPS IFF has to be set to what at all times?
