Honeywell SPZ-8000 - Localizer Approach Mode

3. B.
(7) (d)
From the course cut limiter, the localizer command is routed to
Figure 259, sheet 4, and is processed as discussed in paragraph
3.B.(7)(g).
Localizer Approach Mode (See Figure 259, sheet 3.)
The localizer approach mode provides for automatic intercept,
capture, and tracking of the front
course localizer and glide-
slope signals.
This allows the pilot to fly a fully coupled
ILS approach.
The mode
is set up and flown exactly like the
localizer
mode, with the following differences:
● On the GP-820 Flight Guidance Controller, the APR button is
selected.
With the aircraft outside the normal localizer capture limits,
the PFD will annunciate the following modes at this time:
. HDG in green.
● LOC in white.
. GS in white.
As with the localizer mode, heading select is used
the localizer approach intercept.
Any other vertical mode in use at this time will a-
annunciated on the PFD.
At localizer capture, the

. LOC in green and is boxed for 5 seconds to emphasize the

● GS in white.
. Any other vertical mode in use at the time.
The flight guidance computer now generates a roll command to
smoothly capture and track the localizer signal. With the
localizer signal captured, the aircraft proceeds inbound and,
at the computed time, will automatically capture and track the
glideslope signal. The GS capture overrides all vertical modes
which were previously engaged. At this time, the PFD will
annunciate:
c LOC in green.
. GS in green and is boxed for 5 seconds to emphasize the
capture phase.
The aircraft is now flying a fully coupled ILS approach.
