One little thing that seems consistent (on at least 2.0.1.4 and 5) is that I get exceptions thrown if I try entering cruise altitude or ground speed to a flight plan before adding any waypoints. Easy to work around, but I thought I'd mention it.

 

Also, is there any way for P2A to crash X-plane? Just lately (XP 10.45 and 10.50) I've had silent CTDs for no apparent reason, half an hour to an hour into a flight. Nothing in the XP log, I don't seem to run out of memory, and P2A remains running. I'd put it down to a graphics driver or plugin problem but it only ever seems to happen when I'm running P2A. It takes so long to happen that I can't swear to this, but I haven't completed a single P2A flight lately without a crash, and I don't think I've had a crash when P2A wasn't running. It could still be coincidence, though.

Thanks for the flight plan error report.  I'll look into that one.

 

On the X-Plane crashing, the only thing I can think of are the things you mention - CPU/Memory resources, drivers or the like.  P2A does not interact with X-Plane in any way, other than through XPUIPC.
