1. You are vectored from the holding pattern

to the 13 DME arc. The aircraft is turning,
with the heading bug set on 170° to inter-
cept the localizer. You have already set the
selected course pointer on the inbound ILS
course 130° and the KI 525A shows the
localizer course is directly ahead. The
glideslope pointers came into view when
the ILS frequency was tuned, since a usable
glideslope signal is being received.

2. Capturing the ILS course can be accom-

plished without overshooting or bracketing
with the same technique you used in inter-
cepting an enroute course. Simply keep the
top of the deviation bar on the lubber line
and coordinate your turn until the bar is
centered with the course arrow. Each dot
on the LOC deviation scale represents 1/2
degree of deviation when tuned to an ILS
frequency.

3. The KI 525A shows you that you have inter-

cepted the localizer course. The glideslope
pointers have started to center, although
the display indicates your aircraft is still
below the glidepath at this point.

4. You are now centered on the localizer and

the glideslope. Once again, the KI 525A
shows your aircraft is crabbed about 5° to
the right to maintain the localizer course.

Note: For system limitations refer to your

Flight Manual Supplement.
