Missed Approaches
When you have reached the Missed Approach Point, you must either
decide to land or not land. The Apollo NMS will continue to provide
guidance on an extension of your inbound course to the MAP. The
MAP will remain the active waypoint, the TO/FROM flag will
indicate from, and the Apollo NMS will continue to display navigation
data such as bearing and distance relative to the MAP.
If you have decided not to land, you will then follow either the
published or alternate missed approach instructions. Missed approach
instructions can be very complex. However, the Apollo NMS can be
used to provide guidance for virtually any missed approach.
The steps for a missed approach are as follows:
1.
Begin your missed approach. This
usually includes a procedural clearance
such as: “Fly runway heading to
altitude,” or “climbing left turn to a
heading of xxx.”
2.
Cancel the approach on your Apollo
NMS. Press
OBS/HLD to enable
sequencing and to cancel the approach.
As soon as you enable sequencing, the Apollo NMS will sequence to
the next waypoint in the flight plan. This is the next waypoint in the
published missed approach procedure. Note that if the next waypoint is
the MAHP, it is an automatic holding point and sequencing will again
be automatically suspended. The OBS/HLD light will come back on.
Operation will change from Approach Active to Approach Transition.
The Approach Active light will go out and the CDI will gradually go
back to Approach Transition CDI sensitivity (from 0.3 nm to 1.0 nm
full-scale).
