Approaches and SID/STARs

Chapter 5

For this example assume that the aircraft is approaching KLOU from
the Nabb VOR.

1.

After passing the Nabb VOR, you are told to expect the VOR 24
approach at KLOU. You load the approach using the procedure
described in section 5.1.1.

2.

When the distance from the present position to the destination
airport reaches 30 NM, the KLN 89B will automatically arm the
approach mode. The CDI scale factor will transition to ±1.0 NM
and the KLN 89B will provide more sensitive integrity monitoring.
You also press

A

to update the barometric information.

3.

When the aircraft is 4 NM from the BQM VOR, the KLN 89B will
give a message reminding you to select the OBS mode. The
OBS mode is required for the procedure turn. After passing
BQM, select the outbound course of 068° on the external CDI or
HSI.

4.

The aircraft is now headed outbound for the procedure turn. As
soon a practical, you will need to change the active waypoint to
FF24, the final approach fix. This is done by pulling out on the
right inner knob and scanning
until FF24f is displayed in the win-
dow (figure 5-20) then pressing

D

, then pressing

F

. The OBS

course will still be what is select-
ed on the external CDI or HSI
(68°).

5.

With the OBS mode selected and FF24 as the active waypoint, it
is possible to fly the procedure turn. Allow enough distance past
FF24 to complete the procedure turn and still be 2 NM away
before reaching the FAF. After completing the outbound portion
of the procedure turn, change the selected course to the inbound
course of 248° on the external CDI or HSI.

6.

Once established on the inbound course the Leg mode will again
need to be selected so that proper approach operation and way-
point sequencing will occur.

NOTE: It is mandatory that the unit be in LEG mode with the FAF as
the active waypoint before crossing the FAF to activate the approach
active mode and change to ±0.3 NM scale factor. The CDI scale fac-
tor changes from ±1.0 NM to ±0.3 NM over the two miles to the FAF.
Delaying the switch from OBS to Leg mode compresses the scale
