What is the correct missed approach procedure? How
do I select the missed approach holding point?
The 400W-series unit does not automatically sequence
past the MAP. Waypoint sequencing to the first waypoint
in the missed approach procedure will be enabled when
the
OBS
key is pressed after crossing the MAP. All pub-
lished missed approach procedures must be followed, as
indicated on the approach plate.
To execute the missed approach procedure prior to
the MAP (not recommended), select the active flight plan
page and use the
direct-to
key (by pressing it twice) to
activate the missed approach portion of the procedure.
How do I re-select the same approach or activate a new
approach after a missed approach?
After flying all missed approach procedures, you may
reactivate the same approach for another attempt from the
procedures page
. Once you have been given clearance for
another attempt, activate the approach from the
procedures
page
by highlighting “Activate Approach?” and then press-
ing
ENT
. The 400W-series unit will provide navigation
along the desired course to the waypoint and rejoin the
approach in sequence from that point on. See
Section 4
- Active Flight Plan Leg Selection
for information on activat-
ing a specific flight plan leg.
To activate a new approach for the same airport, se-
lect the new procedure from the
procedures page
. To view
the
procedures page
, press
PROC
and turn the
large right
knob to highlight “Select Approach?”. Press
ENT
and turn
the
large right
knob to highlight the new approach you
want to fly. Press
ENT
to select the approach, then select
the desired transition. Finally, highlight “Activate?” at the
bottom right corner of the screen and press
ENT
to acti-
vate the new approach.
To activate a new approach to a different airport, press
direct-to
and select the desired airport using the
small
and
large right
knobs. Press
ENT
to accept the selected
airport, then follow the steps in the preceding paragraph
to select an approach for the new airport. See
Section 4 -
Flight Plan Options
for more information on selecting and
activating approaches.
NOTE:
Do not attempt to reactivate the same ap-
proach you’re currently on, prior to crossing the
missed approach point (MAP). If you attempt to
do so, an alert message (“Are you sure you want
to discontinue the current approach?”) appears.
If you still proceed with reactivating the ap-
proach, the 400W-series unit directs you back to
the transition waypoint and does NOT take into
consideration any missed approach procedures.
