Alternatively, if your cruise groundspeed is typically less than 150 knots, or if you do not mind the higher
bank angles at the higher groundspeeds, you may want to select the MANUAL mode. In the MANUAL
mode you can set the maximum turn rate to a fixed limit. It is adjustable from 1 degree/sec to as high as
3 degree/sec, in increments of 1/10
th
degree/sec.
To set the TURN RATE selection, perform the following steps:
1. Enter the CONFIGURATION SETTINGS menus as detailed previously and select the MAX
TURN RATE menu.
2. Press and release the HMODE button. The arrow will
be placed at the AUTO (MAN) field
3. Rotate, or press the encoder to change the selection
between AUTO and MAN
4. If a manual rate is desired, select the MAN field and then press and release the HMODE button.
You may take this number as low as 1 degree/sec, but be advised that this will result in very slow
turns and autopilot performance may be unacceptably
sluggish. If AUTO is desired, select AUTO then
proceed to step 6
5. With the arrow selecting the manual rate, rotate the
encoder to select the desired rate
6. Press and release the HMODE button.
The MAN TURN RATE procedure is complete and the encoder can now be used to select another menu
screen.
Circle Last Waypoint Setting
This selection allows you to either home to the last waypoint in a flight plan or GOTO waypoint, or to
track outbound from the last waypoint.
 If the option is set to NO, the Pro Pilot will track directly outbound from the last waypoint in a
flight plan, or the GOTO waypoint. The waypoint identifier will be placed in the lower left display
line upon waypoint passage and will flash for 10 seconds to indicate passage.
 If the option is set to YES, the Pro Pilot will turn the aircraft to effectively “home” to this last
waypoint. Both modes remain in their respective states until the HNAV mode of the Pro Pilot is
changed, or a new waypoint is selected.
To set the CIRCLE LAST WPT selection, perform the following steps:
1. Enter the CONFIGURATION SETTINGS menus as
detailed previously and select the CIRCLE LAST
WPT? screen.
2. Press and release the H MODE button. The arrow
will be placed at the YES (NO) field
3. Rotate, or press the encoder to change the selection
4. Press and release the H MODE button.
The CIRCLE LAST WPT? procedure is complete and the encoder can now be used to select another
menu screen.
Vertical Navigation Servo Deadband
The VNAV servo deadband may be tailored to optimize vertical tracking performance for the particular
airplane. The factory setting of 6 is normally optimal for most application. Lowering this number will
increase the tracking resolution of the system, while raising the number will have the opposite effect.
