mode and ALT appears as the armed mode in the flight mode annunciation
window.
The pilot can then adjust either the vertical speed target using the thumb wheel
or engine thrust to control airspeed during an ALT CHG descent. The capture of
the altitude will occur in the same manner as ALT hold mode. As the aircraft
approaches the desired altitude, ALT remains the armed mode, while active
mode of ALT CHG is replaced by ALT CAP that pulses for three seconds until the
altitude is captured.

APPROACH MODES
LOC APPR and LOC APPR/GS (ILS)
To activate approach mode the APPR button is pressed on the autopilot control
panel. When LOC is selected as the primary navigation source on the PFD, the
flight director will track the course deviation as displayed by the CDI and correct
accordingly. The ACS can make the distinction between a VOR and LOC based
on frequency and will track a localizer frequency with tighter tolerances than it
would normally track a localizer course. When the localizer approach mode is
selected, LOC APPR or LOC BC APPR appears as the standby mode in the flight
mode annunciation window. Once captured, LOC APPR or LOC BC APPR
appears as the active mode in the flight mode annunciation window.
The APPR LOC will enable the GS capture if signal is present for use on ILS
approaches. The flight director will use vertical deviation indication to compute
guidance in order to center it. If the ACS detects a back course signal, it will
automatically reverse the polarity of the CDI. In addition to the appearance of the
LOC APPR armed and active indication, when a glide slope signal is received,
GS appears as the armed indication in the flight mode annunciation window.
When captured, GS appears as the active mode in the flight mode annunciation
window.
VOR APPR
To activate approach mode the APPR button is pressed on the autopilot control
panel. If VOR is the selected as the primary navigation source on the PFD, the
flight director will use the deviation of the Course Deviation Indicator (CDI) to
compute guidance in order to center it. The course is set by using the lower left
concentric knob on the PFD. When selected, VOR APPR appears as the armed
mode in the flight mode annunciation window. Once captured VOR APPR
appears as the active mode in the flight mode annunciation window.
When the autoflight system detects that the aircraft is flying over the station, the
flight director will hold current heading until the VOR signal becomes usable
again (this is commonly referred to at the cone of confusion). When using the
VOR approach mode the lateral tracking tolerance is lowered for better accuracy
during the approach.
