NOTE: While the pilot could have gone directly back to the TRK mode to get back on course, the INT

mode provides a definite (and adjustable) intercept angle to accomplish the return to the course
line. The TRK mode uses a different turn algorithm which may extend the time required to
return to the course line.

Horizontal Use of Pilot Command Steering (PCS)

The Pro Pilot provides a convenient way for the pilot to control the course (CRS) that the airplane flies.
By pressing, and holding, the remote Servo Disconnect switch on the control stick, the pilot can
manually turn the aircraft to the desired course. Upon releasing the button, the autopilot will track that
course. The switch must be held down for a minimum of 5 seconds to engage this feature. Holding for
less than 5 seconds will cause the servo to disconnect and it will have to be re-engaged by pressing the
H NAV and/or the V NAV button on the control/display unit.

If the H NAV servo is turned on (cycled) while in the CRS or INT modes, the current TRK is snapshot as
the commanded CRS or intercept angle

When the remote button is pressed initially, the “H” LED will extinguish normally, and the servo will
disconnect, giving the pilot full control of the aircraft. After the button is held down for 5 seconds or more,
the “H” Servo LED will begin to flash, indicating that the servo will re-engage when the button is
released. This allows the pilot to manually orient the aircraft to the desired course and re-engage the
servo when the button is released.

NOTE: The PCS function also works with the altitude control portion of the Pro Pilot. This is discussed in detail later

in this manual.
