2.11.37 True Wind Angle
Menu Heading: WIND
Function Text: TRUE W/A
Update Rate: Once per second
Units: Degrees
Notes
1. Relative to the boat’s heading.
2. Corrected for masthead and other errors via the Look-up Table (see Part 3
- Calibration).
3. Variable damping 0-99 seconds.
The true wind is calculated from the vector triangle shown in Fig. 2.4. This
uses the apparent wind speed, apparent wind angle and the Boat Speed in
the calculation. The results are then corrected by the true wind correction
tables, which are detailed in Part 3 - Calibration.
Note
The true wind is the wind relative to the water, and is not the same as the
ground wind, unless there is zero tide or current. The true wind angle is the
angle between the boat's heading and the true wind.
