14. The visual descent point is identified by the along
track distance to the MAP to be 1.5 NM. When the air-
craft reaches this point (figure 6-27), and the runway envi-
ronment is in sight, it is possible to descend for a landing.
If a missed approach is needed use the following steps:
15. The missed approach calls for a climb to 2000 and
then a left turn direct to FOW. Since the KLN 900 will not
automatically sequence past the MAP, the KLN 900 will
provide the correct lateral guidance for the climb.
16. Once 2000 feet has been reached press D , the
missed approach holding point will be the default direct to
waypoint. Press
E to confirm the direct to waypoint and
proceed to the FOW VOR.
NOTE: If ATC gives you instructions for a missed
approach that is different from the published missed
approach procedure, it is always possible for you to select
a different direct to waypoint than the default direct to
waypoint.
17. The OBS mode will need to be selected to accom-
plish the holding pattern. If this is not done before the
aircraft getting 4 NM from FOW, the KLN 900 will provide
a message reminding you to select the OBS mode.
NOTE: If another attempt at the approach is desired
after holding, it is necessary to manually change the
active waypoint. When the FAF and the missed approach
holding point are at the same place then the KLN 900 will
automatically change the active waypoint to the FAF
when you change from OBS to LEG. Make sure to make
this change as soon as possible to ensure the approach
active mode becomes the active mode.
6.1.9 Approach Problems and RAIM Availability
Predictions (STA 5)
Very rarely there will be a problem with the integrity of the
GPS system while you are conducting non-precision
approaches with the KLN 900. In some cases the KLN
900 will determine that there will not be sufficient integrity
monitoring for the leg between the FAF and the MAP, or
RAIM is not currently available. In these cases the KLN
900 will not go into the approach active mode and will
present the following message:
RAIM NOT AVAILABLE
APR MODE INHIBITED
PREDICT RAIM ON STA 5
In these cases you will not be able to finish the approach
because there is insufficient integrity monitoring. The STA
5 (Status 5) page provides a means for you to predict
when RAIM will be available.
NOTE: In take-home mode, predicted RAIM will
ALWAYS be available on the STA 5 page. Therefore, the
