Goal Line
A goal line is defined as a line, with a specific length and centered
in a coordinate. By definition the line is perpendicular to the
direction taken from the previous task waypoint to it. Due to
safety reasons it is common to have competition tasks that include
a Goal Cylinder used for measuring time (end of speed section)
followed by a line, or another cylinder, which must be crossed.
In this type of task, the Goal waypoint should be inserted twice,
being the first one set as a Goal Cylinder, and the second one as
Goal Cylinder, or Goal Line. The End of Speed Section will occur
once the first goal is reached. A Goal Line with length of 400m
will extend 200m either side of the centre of the co-ordinate that
is designated as a goal line.
Landing
Most of the times landings can take place at the Goal. In this case
the Goal point may be inserted again which allows the definition
of a Landing limit time. The NAV will then use this limit to
calculate the
Land In
data field. On some occasions, for safety
reasons, landing is recommended to be elsewhere, so a different
waypoint may be used.
When the NAV validates a turnpoint it emits a audible notice informing the user that navigation
has advanced to the next waypoint, this audible notice can be disabled in the
Turnpoint Complete
in the
Alerts
setting (see Section
13.4.1
). by changing the can be changed.
5.2.1
Edit route point
When
task points
are added to the task by default their type with be Cylinder and have a 400m
radius, (except for the first one, as mentioned above, which is set as
Take-off
).

To modify a particular
task point
, select the task point using the UP or DOWN buttons, then
push ENTER to open the Task Point Menu, then select the
Edit Route Point
and push ENTER.
The task point parameters can now be edited. Changing the
task point type
will cause the
Time
field to be displayed when applicable.
Very important:
The sequence in which the waypoints are listed is critical since the NAV will
navigate them in that order, so in the case of a start gate which is also a turn point (as is commonly
used in competition tasks) the start must be placed before the turn point.
The
Time
is only available on turn point types that are time related, so the
Time
field will only
be visible when the turn point type requires a time (e.g. Start gates and goals). Table
5.3
describes
how
Time
data is used for each field type.
