Going To a Destination
One of the many benefits of GPS navigation is the
ability to fly directly to a waypoint or fly along a chain
of waypoints without relying totally on ground-based
navigation aids. To take advantage of the convenience
and efficiency of point-to-point GPS navigation, the GPS
92 provides three methods of selecting a destination for
your flight: GOTO, TracBack and route navigation.
The GOTO function provides a fast way to set a
course to a destination from your present position,
while the route function allows you to create a chain of
waypoints to follow in sequence toward a selected desti-
nation.
Whether you’re flying a GOTO course or a route,
there are a few basic concepts and terms that apply to all
point-to-point GPS navigation. Routes are broken down
and navigated in smaller segments called “legs”. The dia-
gram above shows a basic route consisting of five way-
points and four legs.
The waypoint you are going to in a leg is called the
“active to” waypoint (MAP), and the waypoint immedi-
ately behind you is called the “active from” waypoint
(SGF). The line between the “active to” and the “active
from” waypoint is called the “active leg”. When you acti-
vate a route with the GPS 92, it will automatically select
the route leg closest to your position as the active leg, and
provide navigation guidance directly to the “active to”
waypoint of that leg.
