CDI Comparison: GPS vs. VOR
What is the correct missed approach procedure? How
do I select the missed approach holding point?
The 500W-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, as
described in Section 5 - Procedures.

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 500W-series unit directs you back to
the transition waypoint and does NOT take into
consideration any missed approach procedures.
