Summary0003967: Datum plane yaw setting is ignored
DescriptionThe datum plane yaw setting is ignored if the pitch angle is >= 90°.

Attached is a simple FC file. It contains 2 datum planes.
- edit plane 2 and set its yaw angle to -10°

result: In the preview it looks perfect - both planes are parallel
But when I click OK to finish the editing, the plane yaw angle is reset to 0°, so the change was in fact ignored.

- now set the yaw to -10° and pitch to 89°

result: this works

- now set the yaw to -10° and pitch to 91°

result: you end up with pitch set to 89° and yaw 180°

So in fact the angle setting for datum planes seems to be broken.

With FC 0.19.18234 it is not better:

- take the initially attached FC file
- edit plane 2 and set its yaw angle subsequently (keeping the task dialog open) to -1, -2, -3 and -4°

result: In the preview it looks as if both planes are parallel. But this is wrong because one needs -10° to have both planes parallel

- nevertheless, keep the -4° and click OK to close the task dialog
- open the task dialog for plane2 again

result: you see that the yaw is 0°

- nevertheless to have some fun, set the yaw again to -1, -2 down to -10°

result: you see that the plane is jumping wildly around, for example when going from -7 to -8° or -10 to -11°
