The yoke mounted Autopilot Disconnect Switch disengages the
autopilot and may also be used to mute the aural alert associated with
an AP disconnect.
Flight Director System (Optional)
The Flight Director system enhances situational awareness by
reducing cockpit workload through providing a visual cue for the pilot
to follow as indicated by the PFD’s Flight Director Command Bars.
Through turning or pitching the airplane as “directed” by the Command
Bars, the pilot will follow the necessary course to arrive at a
programmed destination.
The system consists of Flight Director Remote Switches installed on
the upper, LH side of the instrument panel and associated relays and
wiring between the PFD and autopilot. The remaining portion of the
Flight Director system is entirely software dependant. The Flight
Director Remote Switches control system activation and mode. The
switches are automatically dimmed for ambient light conditions by a
phototransistor located on the top of the glareshield.
• Note •
Covering the phototransistor in daylight may result in
unreadable flight director status indication.
The following describes Remote Switch annunciation, color, and
related Autopilot and Flight Director status:
• No Annunciation - Autopilot OFF or Autopilot not active in pitch
control.
• Green AP ON - Autopilot active in roll and pitch control. If
Autopilot active in roll and pitch control, AP annunciation
appears on top edge of PFD, and Flight Director Command Bars
solid magenta.
• Amber AP OFF / FD ON - Autopilot uncoupled. If Autopilot active
in roll and pitch control, Flight Director ON and Flight Director
Command Bars displayed hollow magenta.
The Flight Director system is powered by 28 VDC through the 5-amp
AUTOPILOT circuit breaker on the Essential Bus.
