and therefore not enough altitude to reach the target with the current glider settings. Font
Style, Colour and Size define what font for terrain collision altitude and range circles.
Enable Show range circles to plot range circles around aircraft symbol. Having range
circles on navigational screen, it is much easier to guess distance to nearest point of
interest.
Range colour and range width define the way circles are rendered.
A building engine noise level sensor detects, if engine is running or not. Use Engine colour
and width properties to visualize part of path, where engine was running.
Press the DEFAULT button to reset these settings back to default.
6.1.6.5 Optimization
The main display unit calculates the optimised flown distance according to OLC or FAI rules
in real-time during flight (see Chapter 6.1.9). It calculates the available FAI triangle area,
which is also called the FAI triangle assistant. If you enter this area and return to the start
point your flight forms a triangle according to FAI rules. The Optimisation dialogue is used
to define the look and feel.
Check the Show optimization item to enable display of the optimised track.
Optimization colour and width defines the colour and width for these lines.
If Show optimized triangle is checked also lines for the largest optimised triangle are
shown. Please note this might not be a triangle according to FAI rules.
The FAI Area group defines how the FAI area is drawn. Select the Colour item to change
the colour of the FAI area. Use the ZOOM selector knob to change transparency of the
area. 100% means completely transparent and only the outline will be drawn. 0% means
completely solid (not recommended).
Check the Show km lines item to see lines which indicate what will be the size of the
completed triangle.
These lines will always be plotted in kilometres scale regardless of the Units value.
