Hi diazmr
I'm not with Laminar Research, just a fellow simmer in the UK, but without knowing more information it will be very difficult to determine the cause of the problems you are experiencing. Some questions therefore:-
1. What version of X-Plane are you using?
2. Where did you purchase X-Plane from, Laminar Research or Steam? If it is the latter, please refer all questions to Steam directly as this Q&A does not support Steam products.
3. What aircraft model/s are you referring to?
4. Exactly which avionics controls are you referring to?
Regards
