Using param
e
ters 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 mos
t 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
the start.
•
Prev:
will orient the zone in direction of the incoming leg and is usually used for the
finish.
•
Start:
orientate
s 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
defines half the line
length. Use the PAGE selector knob
to increase
the radius by 0.1 of the selected
d
istance units and the ZOOM selector 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 whilst 45° is the classical FAI
secto
r. Rotate the
PAGE selector knob
to increase the angle by 0.5° or use the ZOOM
selector knob
to choose values 22.5°, 45°, 90° or 180°.
Angle2
and
Radius2
are used for more complex observation zone setups.
Wh
en changing observation zone parameters,
the scr
e
en 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 wi
ll be automatically advanced; uncheck
Auto next
if
you do not want to change over to
the
next point when reaching
the
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
the same time.
