Hi Folks, does anybody know, how to cure this annoying problem I have with the REX WASys. When flying at Flight Levels e.g. FL 310 the WASys plays havoc with the aircrafts IAS's, and the speeds jump up and down from Overspeed to very low speeds. I have to then shut REX Engine (WASys) down, to recover stable Air speeds. I love to run REX along with my FS9 as it is a great weather engine. I'm running on Win 7.
Can anybody please help.
Regards
John

What issues is this causing with FDC?

If it's anything like Activesky (which i use) you can disable winds aloft and have the pressure around your aircraft as if it's the same as ground level, but at your flight level.

You could look in FSUIPC to see if anything can be adjusted in there,
