HDG (HEADING)
The HDG button allows lateral navigation using the HDG only mode. Pressing the
HDG button with the autopilot OFF activates this mode as part of flight director only
navigation. This mode is also activated when Go-Around is selected using the button
on the left throttle.
HDG-SEL (HEADING SELECT)
The HDG-SEL knob allows selection of heading targets for use by the autopilot. This
knob controls the magenta heading bug on the HSI display on the PFD. A heading
pre-select display appears in the upper right corner of the HSI window on the PFD
that displays the digital value in addition to the magenta bug. Rotating the HDG-SEL
knob clockwise or counterclockwise moves the heading bug clockwise or
counterclockwise. Pressing the HDG-SEL knob synchronizes the heading bug with
the current aircraft heading.
ALT CHG (ALTITUDE CHANGE)
The ALT CHG button allows vertical navigation control for climbs and descents.
There are two altitude change modes, climb, and descent. The altitude change mode
is engaged by pressing the ALT CHG button and subsequently setting a higher
altitude using the ALT SEL knob. This initiates a climb using airspeed as the target.
The altitude change descent mode is engaged by pressing the ALT CHG button and
subsequently setting a lower altitude using the ALT SEL knob. This initiates a
descent using vertical speed as the target. When ALT CHG is selected green ALT
CHG text appears in the flight mode annunciation window on the PFD.
THUMB WHEEL (UP/DOWN)
The thumb wheel provides selection of both vertical speed and pitch targets for
climbs and descents. When the autopilot is operating in PITCH only mode, rotating
the thumb wheel up or down adjusts the flight director command bars. When the
autopilot is operating in ALT CHG descent mode, rotating the thumb wheel increase
or decreases the vertical speed target.
ALT (ALTITUDE)
The ALT button allows vertical navigation using the ALT hold mode. Pressing the ALT
button with the autopilot OFF will activate this mode as part of flight director only
navigation and cause the flight director to capture the current altitude. This mode is
also activated as an ARMED mode when ALT CHG is selected.
ALT-SEL (ALTITUDE SELECT)
The ALT-SEL knob allows selection of altitude targets for use by the autopilot. This
knob controls the magenta altitude bug on the altitude tape display on the PFD. An
altitude pre-select display appears at the top of the altitude tape on the PFD that
displays the digital value in addition to the magenta bug. Rotating the ALT-SEL knob
clockwise or counterclockwise increases or decreases the value of the altitude bug.
Pressing the ALT-SEL knob synchronizes the altitude bug, pre-select value and flight
director command bars to the current aircraft altitude.
16.4.2 Flight Mode Annunciation
The Flight Mode Annunciator (FMA) consists of several display fields at the top of the
PFD. These modes appear in green when active and in white when armed. A white
arrow appears in the lateral and vertical portions of the flight mode annunciation
