AUTOPILOT FAILURE
When detecting failure affecting mode integrity, the AP of the affected single
system disengages.
The following events also disengage the on-side AP on the corresponding
AHRS:
• Invalid on-side attitude data
• Invalid on-side attitude rate data
• Invalid on-side yaw rate data
Failure of an AP is annunciated by CAS messages and the AUTOPILOT
AUTOPILOT aural warning message.
SINGLE AUTOPILOT OPERATION
With only one autopilot engaged, the single system operates at full gain with
half the dual system authority. When both autopilots are engaged, each
single system gain is reduced to 50% so that each system supplies half of
the required input. This results in full gain control with twice the single
system authority.
Full yaw control and Autotrim functions are available also in single system
operation.
AUTOPILOT OVERRIDE
The pilot has full authority with the AP engaged or disengaged and can
immediately override the AFCS at any time by simply taking over the
controls.
With the autopilots engaged, FTR switches, AP disengage switches (SAS
REL), detent switches and actuator circuit breakers offer different ways to
partially or completely override the AFCS.
CYCLIC POSITION INDICATOR
The cyclic position indicator is displayed on the ADI to help pilot center the
cyclic controls before starting the engines, to ensure that the main rotor does
not hit the static stops when rotating at low speed.
The indicator is only displayed when the helicopter is on the ground (WOW)
with collective down (LVDT signal via EECs).
Indication is taken from the position sensors located inside the pitch and roll
Trim Actuators.
The cyclic is centered when the indicator shows a green dot; amber arrows
indicate which direction the cyclic stick must be moved to center the controls.
