A realistic display of sail performance requires more influencing parame-
ters, such as wind velocity, ship speed, wind angle. The sail performan-
ce calculation is disabled if these values are not in the system-specific
tolerance range.
In this case the display will show four stars.
The following conditions will disable the calculation:
1. The true wind velocity is less than 4 knots
2. The apparent wind direction is less than 20o
3. The sail performance exceeds 150 % (the engine is running)
4. LOGIC LOG or LOG/DEPTH is not connected.
The Basic Settings
The basic settings needed for a perfect operation are selected by pres-
sing the "PROG" key.
