AFCS Flashcards
AFCS Levels x and x allow for hands off flying?
4 and 5
1: unstablized (no afcs or autopilot on)
2: back-up SAS (sas actuators on only)
3 digital sas (Autopilot on trim motors off)
4 autopilot )attitude retention)
5 autopilot upper modes
Low natural stability of a helicopter requires a x x from the pilot
High workload
Pressing SAS/AP CUT Switch on the cyclic will take you to what level?
1
What system provides attitude hold in the helicopter?
Autopilot
What button on the cyclic must be pressed to move the system from Level 5 upper modes to level 4 attitude hold?
APMD DCPL
In Primary Phase, the UH72 will be flown in Level 3 with FTR off.To select the AFCS must first be in (x) then press the (x) switches on the APMS followed by the (x) switch located on the (x)
Attitude hold, trim, FTR, Instrument Panel
The UH72 AFCS controls the (x), (y) and (z) making it a 3 axis system
Pitch, roll yaw
Which switch on the cyclic is a 4way toggle switch that allows the pilot to modify the attitude reference when operating in ATT (Attitude) Mode?
Beep Trim
The basic structure of the AFCS consists of three types of components
A
B
C
Sensors, computers, actuators
The backup SAS is turned on when the (x) switches are turned on or by pressing the (x) switch on the cyclic
Avionics master, SAS On
Pressing the (x) switch on either cyclic will switch from level 4 Attitude Hold to Level 1 Unstabilized
SAS AP Cut
In Level 1 Unstabilized, pressing the SAS ON button on the cyclic will move the system to level 2 Backup SAS
True? False?
True
The SEMAs provide the actuator input for the (x) to dampen dynamic and atmospheric disturbances (abbr only)
SAS
Which cyclic switch is used to turn off the backup SAS?
SAS/AP Cut Switch
