Operation Manual

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 LX8000 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: This is the most common selection for turn point.
• Fixed: This 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.
If Line is not checked the Angle1 parameter will define the basic shape of the observation
zone. A value of 180° means that the zone is a cylinder and 45° is the classical FAI sector.
Rotate the lower-right knob to increase the angle by 0.5° or use the lower-left knob to
choose values 22.5°, 45°, 90° or 180°.
Angle2 and Radius2 are used for more complex observation zone setups.
When changing observation zone parameters the screen is automatically updated to display
the new zone.
Check the AAT checkbox, if you want to make the selected zone an assigned area. The AAT
checkbox will be automatically checked when Radius1 is greater than 10 km.
By default navigation to task points will be automatically advanced; uncheck Auto next if
you do not want to change over to next point when reaching selected point. This option will
be automatically unchecked when Radius1 is greater than 10 km.
Use Template if you wish to modify start, point and finish zones at same time.
Available templates are:
• 500 m cylinders are used for start, points and finish.
