Autopilot Operation
7-10 EFIS-D10A Pilot’s User Guide
 (HDG, TRK, or NAV)
OFF / ON : The menu label also reflects the currently active lateral mode, and whether or not
the AP is engaged in that mode. Pushing this button toggles between ON and OFF, activating and deactivating the
roll servo in the specified mode. ALT and HDG or TRK modes can be enabled independently of each other. When
the Autopilot is engaged in HDG or TRK mode, the heading bug is synchronized to the current heading or ground
track, respectively. The heading or track bug can then be adjusted while the AP is engaged.
 ALT
OFF / ON : The menu label reflects whether the AP is currently engaged in Altitude Mode. Pushing this button
toggles between ON and OFF, activating and deactivating the pitch servo in altitude mode. When the Autopilot is
engaged in ALT mode, the altitude bug is synchronized to the current altitude. The altitude bug can then be adjusted
while the AP is engaged. When ALT mode is deactivated, the altitude bug is toggled off.
 180: Puts the AP into 180 Mode TRK (or HDG, if no GPS available) and ALT modes, and sets the heading bug to
180º from the current ground track. While in 180 Mode, the 180 button is highlighted, and the AP Status Indicator
displays “180” in the roll axis position.
