5.1.8 Observation Zones
This menu defines the default observation zone geometry. The following items can be
chosen: start zone, turn point zone, finish zone and templates.
Each type of observation zone is defined with two angles, two radii and mean bearing
(
Angle12
). These parameters enable the creation of any known zone geometry separately
for start, turn point and finish.
All tasks stored in the LX9000 will match this “global” setting except those where the zone
was modified in the task edit menu (see Chapter 5.7.1).
Using parameters in the zone dialogue it is possible to describe all types of observation
zones.
Angle12
defines the orientation of the observation zone. Available values for
Direction
are:
•
Symmetric:
which is the most common selection for turn point.
•
Fixed
: which is mostly used for assigned areas.
•
Next:
will orient the observation zone in direction of the outgoing leg. This is usually
used for start.
•
Prev:
will orient the zone in direction of the incoming leg and is usually used for the
finish.
•
Start:
orientates the sector always towards the start.
If the
Line
checkbox is checked the sector will become a line type of observation zone. The
Radius 1
parameter describes half of width of line length. Use the lower-right knob to
increase the radius by 0.1 of the selected distance units and the lower-left knob to increase
the radius by 5.
