LOCALIZER OPERATION
Localizer circuits are automatically energized when an ILS
frequency is selected on the Nav/Comm receiver. By adjusting
the NAV volume level, the localizer station can be identified
and in some cases, ATIS information received. The localizer
flag should disappear from view into the “To” condition
indicating the signal is reliable. Maneuver the aircraft to fly an
on-course centered needle. While flying a front course
approach or outbound on the back course approach, magnetic
heading corrections are made toward the needle deflection.
Similarly, while flying the back course approach or outbound
on the front course approach, corrections are made away from
the needle deflection. The localizer course width is narrow
compared to VOR course width and requires much smaller
course corrections to center the deviation needle. When
intercepting the localizer course, the aircraft turn into localizer
course should be started when the needle moves off the meter
stop. A helpful quick reference reminder of the localizer course
is to set the course on the omni-bearing readout.
GLIDESLOPE OPERATION
The glideslope (horizontal) needle provides the pilot with
vertical steering information during ILS approaches. The
glideslope circuitry may be energized independently or when
the associated localizer frequency is selected on the
navigation receiver. Observe that the glideslope warning flag
is concealed. The glideslope needle deflects toward the
