Display of sail performance (P%)
This function calculates the ratio between the theoretically possible
speed and the current ship speed. The displayed value results from the
sail performance calculation.
Example:
In this example the sail performance is 97 %. To display this value a
VDO LOGIC LOG must be installed in the system.
"Missing" is displayed if there is no connection to a LOGIC LOG.
The following conditions will disable the sail performance calculation:
1. The true wind velocity is less than 4 knots
2. The apparent wind direction is less than 20°
3. The sail performance exceeds 150 % (the engine is running)
In theses cases the function "P(%)" will display four stars.
