Also, intercept direction is
underlined which means it can
be adjusted. With this feature
the system is in a selected
direction mode until the on
course turn (tracking phase) is
initiated. During the intercept
phase of the approach, the
lower left display will alternate
between
INT and NAV or LOC
depending on which mode has
been selected. When the
aircraft is established on the
inbound portion of the
approach, the lower left display
will indicate the selected
course.
If the above is LOC
COURSE and glide slope is
present (ILS), flying below the
glide slope in ALT HOLD
mode will arm the glide slope
coupler. When this occurs, the
display will be as shown below:
When the Glide slope is
intercepted, the display will be
as shown below:
When glide slope coupling
is terminated, by entering either
the ALT
HOLD or SVS
(selected vertical speed) mode,
the lateral mode will switch
from
LOC COURSE to TRK
mode. The selected track will
be the same as the inbound
course.
NOTE: When coupled to
the glide slope, one push of
the VS rocker in either
direction will command a 500
fpm climb.
REV Course Mode
Click the [REV] button to
enter the REV COURSE setup
screen. This refers to flying the
localizer or VOR
in the reverse
direction. Operation of this
mode is the same as
NAV
COURSE or LOC COURSE
except that there will be no
glideslope coupling.
Gyro Back-Up Mode
The lateral modes
previously described are based
on GPS track being present.
When GPS is lost, the autopilot
uses its internal gyros for bank
control, and
TRK is replaced
with BANK . This mode is only
a backup and would seldom be
needed; however, it does
provide a means of selecting a
desired bank angle, and a means
of adjustment if the aircraft
turns when zero bank is
selected. If an external heading
source (HSI or DG) is present,
the
EXT DG mode remains
functional, and if the GPSS or
GPSV signal source is
functional, the GPSS and
GPSV modes will also be
functional. The remaining
modes,
NAV COURSE and LOC
