How do I skip a waypoint in an approach, departure,
or arrival?
The 400W-series unit allows you to manually select
any approach, departure or arrival leg as the active leg of
your flight plan. This procedure is performed from the
active flight plan page
by highlighting the desired waypoint
and pressing
direct-to
twice, then
ENT
to approve the se-
lection (see illustration right). The GPS will then provide
navigation along the selected flight plan leg, so be sure
you have clearance to that position.
NOTE:
If activating a leg while on the From side,
sequencing will be suspended as indicated with
the SUSP annunciation shown above the
OBS
key.
How do I fly the GPS with an autopilot and DG head-
ing bug?
If you do not have an HSI, you should make your
course selections on the external CDI’s
OBS
knob and the
DG heading bug.
When does turn anticipation begin, and what bank
angle is expected?
The 400W-series unit will smooth adjacent leg transi-
tions based upon a nominal 15º bank angle (with the abil-
ity to increase the bank angle up to 30º) and provide three
pilot cues for turn anticipation:
1) A waypoint alert (“LT or RT to ###° x S”) will flash
in the lower right corner of the screen 10 seconds
before the turn point.
2) A flashing turn advisory (“LT or RT TO ###° NOW”)
will appear in the lower right corner of the screen
when you are to begin the turn. Set the HSI to the
next DTK value and begin the turn.
3) The To/From indicator on the HSI (or CDI) will
flip momentarily to indicate that you have crossed
the midpoint of the turn. For more information on
waypoint alerts and turn advisories, see section 5.
When does the CDI scale change, and what does it
change to?
The 400W-series unit begins a smooth CD`I scale tran-
sition from the 2.0 NM (en route mode) to the 1.0 NM
(terminal mode) scale within 31 NM from the destination
airport (see below). The CDI scale further transitions to
2.0° angular (approach mode) at 2 NM prior to the FAF
during an active approach CDI scaling is tightened from
1.0 NM to the angular full scale deflection (typically the
angular full-scale deflection is 2.0°, but will be as defined
for the approach.
If you are in a missed approach situation and would
like to return the CDI to the 1.0 NM scale, activate the
missed approach sequence by pressing the
OBS
key after
you pass the MAP and the annunciation in the lower left
of the screen changes from MAPR to TERM, as described
in Section 5 - Procedures - Flying the Missed Approach.
For this to occur however, the course to the MAHP must
be greater than 3° away from the course line to the run-
way. The CDI scale is also 1.0 NM (terminal mode) within
31 NM of the departure airport.
