Autopilot Operation
7-12 FlightDEK-D180 Pilot’s User Guide
AP Button: When its indicator is off, pressing the AP button engages the AP in the pre-armed mode(s) indicated by the
Horizontal and Altitude Mode button indicators below. Depending on how you have configured bug synchronization, the
AP may synchronize the bugs for pre-armed HDG, TRK, or NAV modes upon pressing the AP button. Read Pre-select
Configuration on page 7-14 for more details on configuring this behavior for your needs. If no mode is armed, pressing
the AP button engages the AP in HDG mode only.
When the AP button’s indicator is on, pressing the AP button disengages all axes of the AP, but leaves the last-used
modes armed (unless configured to clear modes in setup). If you push and hold the AP button for 2 seconds, the AP
engages in 180 Mode.
VALUE Knob: When no menus are displayed, the VALUE knob changes the BARO, ALT bug, and HDG bug settings.
When in any EFIS menu which adjusts a numerical value, turning the VALUE knob adjusts the selected parameter.
Pressing the VALUE knob when in any menu exits the menu system completely. Pushing and holding the knob while
changing a bug synchronizes the bug to the current value. Pushing and holding the knob while changing the BARO sets
the barometer to 29.92 inHg. Further behavior can be configured, as described on page 7-13.
HDG Button: When its indicator is off, pressing the HDG button arms the roll servo in Heading Mode and turns on the
indicator. Depending on how you have configured bug synchronization, the heading bug may be synchronized to the
current heading value upon pressing the HDG button. Read Pre-select Configuration on page 7-14 for more details on
configuring this behavior for your needs. The heading bug can always be adjusted while the AP is engaged.
When its indicator is on, pressing the button disarms/deactivates the roll servo and turns off the button’s indicator.
TRK Button: When its indicator is off, pressing the TRK button arms the roll servo in Track Mode and turns on the
indicator. Depending on how you have configured bug synchronization, the heading/track bug may be synchronized to
the current GPS ground track upon pressing the TRK button. Read Pre-select Configuration on page 7-14 for more
details on configuring this behavior for your needs. The heading/track bug can always be adjusted while the AP is
engaged.
