6. When the aircraft is 2 NM from the FAF, the KLN 90B
will verify that the proper GPS integrity is available. If
integrity monitoring is available for the approach, then the
KLN 90B will change to the Approach Active mode. This
will be annunciated on the external approach status
annunciator as well as on the KLN 90B. The CDI scale
factor will also start to change from ±1.0 NM to ±0.3 NM.
7. 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 will become
active and the CDI scale factor will remain at ±0.3 NM. If
the AUTO scale factor was selected on the Super NAV 5
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 NM and the
runway diagram becomes visible on the map.
The following steps are followed if a missed approach is
required.
8. The missed approach instructions call for a climbing
left turn to a heading of 110° until intercepting the 061°
inbound course to the missed approach holding fix,
SCUMY. To fly this with the KLN 90B it will be necessary
to put the KLN 90B into the OBS mode and make
SCUMY the active waypoint. Change the selected course
on the external CDI or HSI to 061°.
9. Once the aircraft reaches SCUMY, you will need to
perform a holding pattern entry suitable for this holding
pattern and set the selected course to 241° for the
holding pattern.
