EQUIPMENT OPERATION
All controls required to operate the KI 208, KI 209 are located on the unit's front panel
and on the front panel of the related NAV/COMM transceivers.
3.1.1
VOR OPERATION (KI 208, KI 209)
Select the desired VOR station frequency with the NAV frequency controls. The NAV
receiver volume control can then be adjusted to positively identify the station or listen
to FSS reports.
To intercept a selected VOR radial (from the station) and fly outbound, turn the OBS
control to set the desired radial under the top indicator index. Maneuver the aircraft to
fly the selected radial magnetic heading plus a 45° intercept angle which will provide
a sufficient intercept angle. The intercept angle should be reduced as the deviation
needle approaches an on-course condition (center) to prevent excessive course
bracketing.
To determine the bearing and fly "To" a selected VOR station, turn the OBS control
until the "To-From" flag resembles a white arrow pointing up and the deviation needle
is centered. Read the "To" bearing under the top indicator index and maneuver the
aircraft to approximately fly the magnetic course "To" the station. If the deviation nee-
dle moves to the right, the aircraft course must be adjusted 5 or 10 degrees to the right.
Similarly, if the deviation needle goes to the left, the aircraft course must be adjusted
to the left. Maintaining a centered deviation needle will provide automatic course com-
pensation for wind drift.
3.1.2
LOCALIZER OPERATION (KI 208, KI 209)
Localizer circuits are automatically energized when an ILS frequency is selected on
the KX 155, KX 155A. By adjusting the NAV volume level, the localizer station can be
identified and in some cases, ATIS information received. The localizer flag should dis-
appear 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 ap-
proach 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 nee-
dle moves off the meter stop.
