Section 5
Direct-to & Route Navigation
One of the many benefits of GPS navigation is the ability to fly directly to a way-
point or fly a chain of waypoints without using ground-based navigation aids. To take
advantage of the convenience and efficiency provided by point-to-point GPS naviga-
tion, the GNC 250 provides two basic methods of selecting a destination for your
flight: direct-to and route navigation. The direct-to function provides a fast way to
set a course to a destination waypoint from your present position. The route function
allows the pilot to create a chain of waypoints to fly in sequence.
As you pass each waypoint in the route, the GNC 250’s automatic leg sequencing
and turn anticipation features will automatically select the next waypoint as the
‘active to’ waypoint and provide smooth steering guidance around the turn. If you are
not currently navigating a particular route leg (e.g., your starting position is not a
route waypoint), the GPS will select the appropriate leg as the active route segment.

ROUTE TERMINOLOGY
The diagram at the right shows a basic route
consisting of five waypoints and four legs.
The waypoint you are travelling to is called the
‘active to’ waypoint, and the waypoint immediately
behind you is called the ‘active from’ waypoint. The
course line between the active from and the active to
waypoint is called the ‘active leg’.
