A follow up on this one ...
For the specific mission I was working on I was able to use the headwind work-around at 5 m/s and redid the Task Force waypoints so that they were turning into the wind for aircraft takeoff and retrieval. So after repositioning about 130 waypoints and readjusting mission timings this solved the problem in this case and makes the mission more realistic also, but I'd still like to see improved directional control in itself.
So thanks to those who offered work-around suggestions. It has allowed me to produce a better behaving mission as a result. And some of you may have noticed this historical mission, titled "Wildcat Ace over the Norwegian Sea" is now uploaded to mission4today as below:
