Configuration Setting Description
Control Wheel Steering
(configuration mode only)
The CWS/DISCONNECT discrete input to the GSA 28 servos is
connected to a momentary pushbutton which can function either as a
dedicated Autopilot Disconnect (AP DISC) button, or as a combined
Autopilot Disconnect / Control Wheel Steering (AP/CWS) button.
Regardless of configuration, a short press and release of the AP DISC or
AP/CWS button will disengage the autopilot if it is engaged.
If Control Wheel Steering is enabled, the pressing and holding the AP/
CWS button places the autopilot into CWS mode. In CWS mode, the
servos are temporarily disengaged, allowing hand-flying the aircraft to a
new aircraft attitude while continuing to hold the AP/CWS button. When
the AP/CWS button is released, the autopilot exits CWS mode and the
flight director synchronizes to the current aircraft attitude (if applicable for
the current flight director modes).
If Control Wheel Steering is disabled, CWS is not supported and the AP
button serves as a dedicated AP DISC button only. The AP DISC button
will disconnect the autopilot any time it is pressed, regardless of how long
it is held.
Engage AP Via CWS Input
(configuration mode only)
If Control Wheel Steering is enabled, the AP/CWS button can optionally
be configured to engage the autopilot when pressed and held.
If "Engage AP Via CWS Input" is enabled, the autopilot will automatically
engage when the AP/CWS button is pressed and held.
If "Engage AP Via CWS Input" is disabled, pressing the AP/CWS button
while the autopilot is not engaged has no effect. In this state, the autopilot
can only be engaged using the GMC Mode Controller AP button or the
softkeys on the PFD display.
Autopilot Engage Limits
When engagement limits are enabled, the autopilot may only be engaged
within the following ranges:
Pitch 50° nose up to 50° nose down
Roll ±75°
If the above pitch or roll limits are exceeded while the autopilot is
engaged and while Autopilot Engagement Limits are enabled, the
autopilot will disconnect.
Engaging the autopilot outside of its command limits, but within its
engagement limits, will cause the autopilot to return the aircraft within
command limits.
