Autopilot Preferences Menu
The Preferences Settings menus are designed to allow setting of various parameters while the autopilot
is being used in flight. For example, the HNAV fine tracking gains may be adjusted for optimal
navigation tracking performance for a particular airplane and GPS. Setting of the trim speeds for the
VNAV servo is another example of in-flight adjustments
Using the Preferences Menu
To enter the Preferences Menu, press and hold the encoder knob for a period of 3 seconds while in the
navigation display. The navigation display will be replaced by the setup screens. Paging through the
setup screens is accomplished by repeatedly pressing the encoder knob or by rotating the encoder knob.
Once the appropriate screen has been selected, press the H MODE button to activate the cursor and
place the triangular arrow next to the value that is to be adjusted. Once the cursor is in place, rotate the
encoder or, in some cases, press the encoder to change the value. The value will not change if the
triangular arrow is not present on the display screen.
To exit that screen, press the H MODE button until the cursor is no longer present on the display. It is
now possible to use the encoder to page through the setup screens.
To exit the menu, press and hold the encoder knob for a period of 3 seconds and the screen will return to
the navigation functions.

Backlight Set and Display Brightness Set (OLED Model Only)
This display screen that is shown on this menu item will depend upon which display module has been
installed in the Pro Pilot – OLED or LCD.
The BACKLIGHT SET applies to both the LCD and OLED models and controls the backlighting of the
indicators, LED’s and buttons. The BACKLIGHT SET also controls the backlighting of the LCD screen
(but not the OLED screen which has its own separate lighting menu). It allows setting the level of the
display if the remote analog dim (panel dimmer) interface is not being used. The BACKLIGHT SET
setting has nine levels of intensity with a setting of 1 being the dimmest setting.
The DISPLAY BRT value adjusts the brightness of the characters that appear on the OLED screen. This
setting also has nine levels of intensity with a setting of 1 being the dimmest setting. NOTE: When the
external dimming feature is employed (using the aircraft panel dimmer) a maximum of 8 levels is
available.
