Missed Approach
pended at the MAP. A “from” indication will
be displayed on the CDI and default NAV page,
but course guidance along the final approach
course will continue. If a missed approach is
required, use the
OBS
key to initiate the missed
approach sequence.
Flying the Missed Approach
After you pass the MAP, if the runway isn’t in sight
you must execute a missed approach. The 400W-series
continues to give guidance along an extension of the final
course segment (FAF to MAP) until you manually initiate
the missed approach procedure (as mentioned previously
in reference to the “SUSP” advisory).

DO NOT USE FOR
NAVIGATION
NOTE:
It is the pilot’s responsibility for initial
missed approach guidance in accordance with
published procedure. The unit may not provide
correct guidance until established on a defined
leg.
The
OBS
key is used to initiate the missed approach,
as follows:
1. After commencing the published missed
approach procedure, and after the SUSP
annunciator has appeared, press the OBS key
to sequence to the first waypoint in the missed
approach procedure. This will simultaneously
result in several changes:
a. SUSP annunciation will extinguish.
b. The first waypoint in the missed approach
procedure will be sequenced.
c. The current approach annunciation (LPV,
L/NAV, LNAV+V or LNAV) will be replaced
with either MAPR or TERM, depending
on the design of the approach. Normally,
MAPR will be annunciated for missed
approach procedures in which the first leg
is a climb straight ahead to a waypoint,
whereas TERM will be annunciated for
missed approach procedures requiring a
turn.
d. CDI scaling will change to
±
0.3 NM full
scale deflection if MAPR is annunciated,
or
±
1.0 NM if TERM is annunciated.
e.
The “FROM” indicator will change to a
“TO” indication.
NOTE:
In some cases, an additional hold way-
point is added to the missed approach sequence.
This additional waypoint is used as an aid in
establishing the holding pattern—
especially where the MAP and MAHP are the
same waypoint.
2. An alert message in the lower right hand corner
of the screen will recommend entry procedures
for the holding pattern (i.e., “HOLD DIRECT”,
“HOLD PARALLEL”, or “HOLD TEARDROP”).
