Eventide ARGUS 5000 - Page 20

So much for the administrative stuff, let's go flying! Our trip today will be from N07
(Lincoln Park NJ) to ABE (Allentown-Bethlehem PA), a trip of some 54 nm. If
you're following along with your GPS in training mode at home, set these up as
departure and destination waypoints.

departure route.
Assuming that the GPS is working and has acquired, the
Argus may show a display like that at the left. Note that
the bearing and distance to the waypoint (ABE) is given,
but the graphic display area shows NO HEADING OR
TRACK. That's because we're not moving, so there is
no track or groundspeed. The mode shown is PLAN,
because that's always the first display seen. This mode
"autoranges" so that the most distant waypoint is always
shown at the edge of the screen. Some GPS models will
give incorrect position and track information before
acquisition. If the Argus is connected to the aircraft
compass system, the map will be displayed and oriented
correctly even if the aircraft isn't moving.
As we begin taxiing to runway 19 (ground TK 010°),
the PLAN display appears, showing the destination to
our left. Depending on the GPS, this display may
appear sooner or later during taxiing. It may also
appear somewhat erratic while we're on the ground
since our speed will be low and the GPS may have
difficulty following our tight turns while taxiing. From
the PLAN mode we can determine how to proceed.
We'll be taking off on runway 19, so it would seem that
a right turnout would be the best procedure. Note that
special use airspace is not shown in PLAN mode.
When we go to DEParture, we'll see that we're under
the floor of the New York Class B airspace and near
two controlled airports. This will slightly affect the
