autopilot engagement. Pressing the button a second time disengages the autopilot,
reverting to the flight director only mode.
NOTE:
Disengaging the autopilot using the AP OFF/ON button does not disengage the
yaw damper.
ATS OFF/ON (AUTOTHROTTLE OFF/ON)
The ATS OFF/ON button engages and disengages the autothrottle system. The first
press of the autothrottle button engages the autothrottle. When engaged, the
autothrottle defaults to the SPD HOLD mode of operation, a green light on the ATS
OFF/ON button illuminates and the autothrottle modes appear as green text in the
flight mode annunciation window on the top of each PFD.
NOTE:
The autothrottle system may only be engaged with the autopilot engaged.
SPD-SEL (SPEED SELECT)
The SPD-SEL knob allows selection of airspeed targets for use by the autopilot and
autothrottle. This knob controls the magenta airspeed bug on the airspeed tape. A
speed pre-select window appears directly above the airspeed tape that displays the
digital value in addition to the magenta bug. Rotating the SPD-SEL knob clockwise or
counterclockwise respectively increases and decreases the value of the airspeed
bug. Pressing the SPD-SEL knob synchronizes the airspeed bug and pre-select
value to the current airspeed.
NAV (NAVIGATION)
The NAV button allows lateral autopilot navigation based on the selection of the
primary navigation source on the PFD. The three sources of information for this
mode are, VLOC1, VLOC2, or FMS. Pressing the NAV button with the autopilot OFF
will activate this mode as part of flight director only navigation.
APPR (APPROACH)
The APPR button allows lateral and vertical autopilot navigation based on the
selection of the primary navigation source on the PFD. The lateral approach modes
are LOC (localizer), LOC BC (localizer back course), VOR, FMS, while the only
vertical approach mode is GS (glide slope) for ILS approaches. Pressing this button
will ARM the appropriate approach mode and show following white text on the flight
mode annunciation window:
1. Lateral Modes
a. LOC BC APPR
b. LOC APPR
c. VOR APPR
d. FMS APPR
NOTE:
LOC APPR appears for both localizer and ILS approaches
