How do you momentarily disengage altitude hold when changing altitudes?
Thrust brake
When flying in known or forcast moderate or above turbulance, what are the three concerns/restrictions the pilot should be aware of?
Do not use BALT hold, ensure thrust brake operation, LCT in MAN
Will the cyclic move when the DAFCS trim switch is moved laterally?
No
Should BARO ALT hold be used in moderate turbulance or above?
No
Which actuator makes the control input for positive stick gradient, pitch attitude, and airspeed hold purposes?
DASH
What is the status of the Heading Stability feature when the Swivel Lock Switch is not in the LOCK pistion?
DAFCS Heading Hold is degraded
Will the Longitudinal Cyclic Trim Actuators function with the DAFC Switch in the off postion?
Yes
With the Translational Rate Command captured, what happens to the status of the TRC when either WOW switch engages?
Disengaged
When flying in moderate turbulance or above, should BARO ALT be engaged?
No
What is the name of the DAFCS component which the #1 Fligh Control Computer control to provide Altitude Hold?
Thrust CCDA
Which DAFCS computer controls the radar and inertial altitude hold?
FCC1
How do the flight control computers know to place the LCT actuators to the GRD position when in AUTO?
Both WOW switches engage
What should you do if the LCT actuator fails to postion to GND during taxi, water, or slope operations?
Place LCTs in Manual
When accelerating from a hover, what is the max groundspeed which can be flown to remain within the Low Speed Regime?
20 KGS
At what groundspeed does the TRC feature become active or captured?
Below 9 KGS
Name two features of DAFCS that disengage when the Centering Device Release switch is pressed?
Bank Angle Hold, Heading Hold
What are the three control laws for the DAFCS?
Forward Flight, Low Speed, Ground
What is the maximum aircraft bank angle with altitude hold?
45
What is the maximum allowable airspeed when operating with both DAFCS OFF?
160 KCAS
What is the maximum allowable airspeed when operating with a single DAFCS ON?
100 KCAS
What must be monitored to prevent transmission damage when changing airspeed ot heading with ALT HOLD engaged?
Torque
Which Flight Control Computer control the Pitch CCDA?
FCC2
At what groundspeed will the Low Speed Regime become active when decelerating?
16 KGS
If you have a hard-over with both DAFCS on, how will you know when you have the good system selected ON and the malfunctioning system OFF?
Reverse Hard-Over
What action is required to release the Thrust Magnetic Brake?
Depress the Thrust Brake Switch
How will the aircraft react if DAFCS is turned Off at one airspeed and back on at a different airspeed?
Pitch Transients, adjusting to go where it was turned off
What visual indications will you see when the DASH Actuators are re-centering when the DAFCS is first turned on?
DASH Caution Lights
Do not manually extend the LCT actuators beyond GND position on the cyclic trim indicators at airspeed below ____ KIAS
60
Describe one way you can change the aircraft bank angle without moving the cyclic?
AFCS Trim Switch
Which mode of LCT operation should you select during flight in moderate or above turbulance?
Manual
What does the acronym CPT stand for?
Control Position Transducer
What does the acronym LVDT stand for?
Linear Variable Differential Transducer
What is the name of the portion of the Integrated Lower Control Actuator that is controlled by the DAFCS Flight Control Computer?
Extendible Link
How accurate is the DAFCS Heading Hold feature?
+/- 5 degrees
When the landing gear proximity switches are active, the DAFCS input into the Pitch ILCA is reduced by what percent?
50
What 3 DAFCS features are provided by the DASH actuator?
Airspeed Hold, Pitch Attitude Hold, Positive Stick Gradient
Which Flight Control Computer controls the Thrust CCDA?
FCC1
At what groundspeed does the Position Hold feature become active?
1 KGS
Is “Go Around” a DAFCS feature or a feature of the Flight Director?
Flight Director
When can radar altitude hold be used in forward flight?
Over water or known flat terrain
Does the cyclic have to be centered for the cyclic to be in detent?
No
Should you allow the cyclic to move when the AFCS trim switch is moved forward or aft?
Yes
