AREA NAVIGATION WAYPOINT PROGRAMMING
(1)
Presentation Of Waypoint On Ground
Waypoints
are entered after engine start, since the waypoint
information
will probably
be lost during the
low-voltage
condition occurring
during engine cranking. Waypoint
data
should always be written in flight planning
form
to
facilitate
checking later in flight. When power
is first
applied
to the
ANS 351 and the system is in the RNAV mode, waypoint
number
1 will be active,
(waypoint
number
not
blinking) and
waypoint bearing and distance
preset to
zero
will appear.
a.
Waypoint number
l coordinates
are set
into the ANS
351
using concentric knobs under
bearing and distance display
fields.
b.
The waypoint selection knob is then rotated
to select way-
point number 2. Note that the waypoint number is blink-
ing,
indicating
that the waypoint
is
at this point
inactive.
Waypoint number 2 bearing and distance definitions
are
then
set into the ANS 351.
c.
Set up the
rest
of the desired waypoints as described above.
d.
Press the RTN
(return)
pushbutton to display the active
waypoint.
(2)
Changing Waypoints
In
Flight
To change a waypoint in flight,
rotate
the waypoint
selector
until the
desired waypoint number and coordinates are dis-
played on the ANS 351.
a.
Verify
that
the waypoint definition is correct by comparing
the display with
the flight plan.
b.
Uncouple
the
autopilot if tracking
RNAV deviation.
c.
Select
the
desired
reference facility frequency
on the
associated NAV receiver.
d.
Depress the USE pushbutton
and note that the waypoint
identification
number
stops winking.
e.
Select the
desired course on OBS.
f. Recouple the
autopilot after
deviation and distance-to-
waypoint indications
have stabilized.
