approaching from the Northeast going Direct-to the Clovis airport with
no active flight plan.
1. Load the approach into the flight plan as described in section
5.1.1. In this case there is only one IAF so the KLN 89B does not
present the option for you to select an IAF. In this example, there
is no active flight plan to begin with so the KLN 89B will ask to
add the approach to FPL 0.
2. Approaching the area ATC tells you to go direct-to the TXO VOR
and clears you for the approach to KCVN. This is easy to do
from the NAV 4 page by pulling out on the right inner knob and
scanning through the active flight
plan by turning the inner knob.
Once TXO is displayed in the
scanning window (figure 5-17),
press
D
and then
F
to initiate
a direct to operation to the TXO
VOR.
3. At a distance of 4 NM to the TXO VOR, the KLN 89B will give the
following message:
*If Required Select OBS
This message provides a reminder that to fly a course reversal the
OBS mode needs to be selected. Note from the approach chart that
there is a NoPT Arrival Sector for this approach. If you are approach-
ing TXO within the indicated area there is no need to perform a
course reversal and you need to ignore this message. The NoPT
sector is not stored in the data base so it is not possible for the KLN
89B to know if a course reversal is required or not; as a result, the
KLN 89B will always give this message whenever a waypoint could
be used for a course reversal. The KLN 89B will properly sequence
to the FAF to MAP leg and transition to the approach mode when 2
NM from the IAF/FAF.
If, however, you are approaching from any other direction a course
reversal is required and the OBS mode will need to be selected. If
the OBS mode is not selected before reaching TXO, then the KLN
89B will automatically sequence to the missed approach point. This
is not desirable when performing a course reversal so the OBS mode
must be selected before reaching TXO.
NOTE: The KLN 89B will only remind you to select OBS mode if the
IAF is the active waypoint. Therefore if a course reversal is required,
make sure the IAF is the selected waypoint.
