6.1.4 Example Approach: No Procedure Turn
Now that you know the basics of inserting an approach
into the flight plan, we can now show the approach opera-
tion of the unit by several examples. This first example
will use the approach that was loaded into the flight plan
in section 6.1.1. This example will show how the KLN
900 sequences through an approach and what type of
annunciations and scale factor changes can be expected.
The KLN 900 will remain in the familiar Leg mode so
there will be no need to change between Leg and OBS
mode in this example. Refer to the approach plate for
this approach (figure 6-13) to see what the procedure
looks like.
For this example it is assumed that you are on an active
flight plan with the final destination being the Los Angeles
International airport, KLAX. It is also assumed that ATC
will not give you radar vectors during this approach.
1. Load the VOR 25R approach to KLAX as
demonstrated in section 6.1.1.
2. When you are within 30 NM of the airport, the
KLN 900 will automatically arm the approach mode and
provide the following message.
PRESS ALT TO SET BARO
The message acts as a reminder to make sure the
KLN 900 is using the correct barometric pressure. If the
barometric information is not correct, then the integrity
monitoring provided by the KLN 900 will not be as good
as it could be. Press
A
to bring up the ALT page and
verify that the barometric pressure is correct.
NOTE: If the KLN 900 is interfaced with a compatible air
data computer that provides the correct barometric pres-
sure to the KLN 900, then the previous message is not
displayed and it is not necessary to update the barometric
pressure.
At this time the KLN 900 will smoothly change the CDI
scale factor to ±1.0 NM. The external approach annunci-
ator installed in the aircraft will indicate that the approach
is in the ARM mode.
3. As you approach ELMOO, the KLN 900 will provide
waypoint alerting on the external annunciator as well as
on the screen of the KLN 900. Once you pass ELMOO,
the KLN 900 will automatically sequence to the next way-
point in the approach, LAX18.
4. This may be a good time to select the Super NAV 5
page. This page is especially useful for getting a feeling
of where you are in the approach (figure 6-14).
5. As the aircraft approaches the LAX18 waypoint, the
KLN 900 will again provide waypoint alerting. As the
aircraft passes LAX18 and sequences to FITON, the KLN
