6.3 FLIGHT DIRECTOR MODES
Flight director modes are normally selected
independently for the pitch and roll axes. Unless
otherwise specified, all mode keys are alternate action
(i.e., press on, press off). In the absence of specific mode
selection, the flight director reverts to the default pitch
and/or roll mode(s).
Armed modes are annunciated in white and active in
green in the AFCS Status Box. Under normal operation,
when the control for the active flight director mode is
pressed, the flight director reverts to the default mode(s)
for the axis(es). Automatic transition from armed to active
mode is indicated by the white armed mode annunciation
moving to the green active mode field and flashing for ten
seconds.
A flashing yellow mode annunciation and annunciator
light indicate loss of sensor (AHRS, ADC, IAU) or
navigation data (VOR, LOC, GPS, VNAV, WAAS) required
to compute commands. When such a loss occurs, the
system automatically begins to roll the wings level or
maintain the pitch angle, depending on the affected axis.
The flashing annunciation stops when the affected mode
key is pressed or another mode for the axis is selected.
If after ten seconds no action is taken, the flashing
annunciation stops and the flight director enters the
default mode for the affected axis.
Figure 6-4 Loss of VOR Signal
If the information required to compute a flight director
mode becomes invalid or unavailable, the flight director
automatically reverts to the default mode for that axis.
The flight director is automatically disabled if the attitude
information required to compute the default flight director
modes becomes invalid or unavailable.
Pitch Modes
•
Pitch Hold
(default mode)— Holds the current
aircraft pitch attitude; may be used to climb/descend
to the Selected Altitude
•
Selected Altitude Capture
— Captures the
Selected Altitude
•
Altitude Hold
— Holds the current Altitude
Reference
•
Vertical Speed
— Maintains the current aircraft
vertical speed; may be used to climb/descend to the
Selected Altitude
•
Flight Level Change
— Maintains the current
aircraft airspeed while the aircraft is climbing/
descending to the Selected Altitude
•
Vertical Path Tracking
— Follows an active
vertical profile for enroute and terminal phases of
flight (only available with WAAS capable system)
•
VNAV Target Altitude Capture
— Captures the
VNAV Target Altitude
•
Glidepath
— Intercepts and tracks the WAAS
glidepath on approach (only available with WAAS
capable system)
•
Glideslope
— Intercepts and tracks the ILS
glideslope on approach
•
Go Around
— Automatically disengages the
autopilot and commands a constant pitch angle and
wings level while in the air
