PA-28R Arrow III from Just Flight

Had the same issues at least with 0.3.0, did not do a longer flight since the update.
It was also not reproducible and given the fact that there are many people experiencing CTDs, I don’t think it is specific to the PA28R.

I had a post here on my CTDs with more details, maybe you want to have a look if there are similarities/differences for you - these happened with the PA28R:

There’s also a thread on the JF forum about CTDs talking about the GNS530 that could be the issue, but I think this is just biased since of course in a PA28R forum you’ll find most people experiencing CTDs will be flying that aircraft.
But you can read a lot about CTDs with the CRJ etc. here on the forum.
