No calculation of True wind angle and true wind speed if navigation.headingTrue can not be calculated.

[Asw1n]

There is oone calculation that calculates three delta's; True wind angle, true wind speed and true wind direction.
Two of these, TWA and TWS, can be calculated from navigation.speedThroughWater(👍), environment.wind.speedApparent(👍), environment.wind.angleApparent(👍)]. True wind direction needs [navigation.headingTrue(👍) as well. If navigation.headingTrue is not calculated, because of null values (see the other issue I reported on 13 oct 2024) then TWD cannot be calculated. But also TWA and TWS will not be calculated, even if all the source data is available for these calculations is available.
