or DOWN buttons will move between the Task points. For the highlighted
task point
, the bottom
screen area will display the
task point
parameters.
When a task has only one point it is considered as a
Go To
type route. The NAV will automat-
ically start navigating to that point.
When the task contains more than one point then the first turn point will automatically be set
as
Take-Off
. The
Take-off
is ignored for navigation proposes and is only used for calculating the
total task distance.
Each
task point
defined has a particular type, by default it will be set to Cylinder (see Table
5.2
for a description of the various task point types).
Pushing ENTER while on a selected task point will open a
Task Point Menu
(at the bottom of
the screen in the DO area), which will allow you to
Edit
,
Move
or
Remove
a task point from the
task.

Navigation
Take off
This first task waypoint is automatic defined as Take-Off. This
waypoint, however, is only a place marker for calculating the entire
task length. The NAV will ignore it for navigation purposes.
Cylinder
The cylinder type is defined by a coordinate and a radius. The
coordinate is taken from the chosen waypoint and the radius can
be defined by the user. The default value (usually 400m) for the
radius is defined in the
Turnpoint Size
settings. During naviga-
tion, NAV will advance to the next task waypoint once the pilot
transitions over the cylinder line.
Start In/Exit
Start In route waypoints are start gates, sometimes also known
as
Exit start
. NAV will only validate the waypoint, and advance
to the next waypoint on the route, if the user is inside the set
radius after the start time. Note that the sequence in which this
waypoint appears in the task list in very important (see Note 5).
Start Out/Enter
Start Out is the most commonly used start gate, sometimes also
known as an
Entry start
. NAV will only validate this waypoint,
and advance to the next waypoint, when the user is outside the
radius after the start time. Note that the sequence in which this
waypoint appears in the task list in very important (see Note 5).
Goal Cylinder
The goal cylinder is very similar to the Cylinder, expect for the
fact that it has a
Closing Time
.
The closing time is used to
calculate the Goal Close user defined field.

Warning:
Whenever a modification if done to the task, navigation will be restarted at the beginning of the route.
In this can you can use the
Task Navigator
to force the navigation from a desired waypoint (see Chapter
7
).
