Honeywell BENDIX/KING KLN 94, Pilot'S Manual

Page: 205 / 284

NOTE : For ORS 02 and higher units
the procedure turn will be displayed
on the map (figure 6-44a) if config-
ured to do so on the SET 7 page.
See section 3.11.4.12 for information
on displaying procedure turns on the
map.
Allow enough distance past HOWFA to complete the procedure turn
and still be 2 NM away before reaching the FAF. Remember to
remain within 10 NM of MSA per the chart. After completing the out-
bound portion of the procedure turn, change the selected course to
the inbound course of 360° on the external CDI or HSI.
7. Once established on the inbound course press the
H
button to
select the Leg mode so that proper approach operation and waypoint
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 factor 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 factor change. This
makes the transition more abrupt. If the switch from OBS to Leg is
delayed too long it will not be possible for the KLN 94 to change to the
approach active mode.
8. When the aircraft is 2 NM from the FAF, the KLN 94 will verify that the
proper GPS integrity is available. If integrity monitoring is available for
the approach, then the KLN 94 will change to the Approach Active
mode. This will be annunciated on the right side of the KLN 94 by
APR ACTV (or APR ). The CDI scale factor will also start to change
from ±1.0 NM to ±0.3 NM.
9. Normal waypoint alerting will occur as the aircraft passes the final
approach fix. The leg from the final approach fix to the missed
approach point (
MSAm ) will become active and the CDI scale factor
will remain at ±0.3 NM. If the AUTO scale factor was selected on the
NAV 4 page, then the scale factor will zoom in on the airport as the
aircraft gets closer and closer to the missed approach point.
Eventually the map scale changes to 1/2 NM.
The following steps are followed if a missed approach is required.
10. The missed approach instructions call for a climbing right turn to 2000’
in the MSA holding pattern. After passing the MAP press the
D
but-
ton to bring up the direct to page showing the first waypoint in the
