Hello,

I am flying a Bonanza F33A in Germany with 2 IFD and an Aspen Pro Max.
The KFC200 is becoming increasingly unreliable.
In this constellation, practically only the DFC90 or the S-Tec 55x come into question.

The procedure first S-Tec then DFC is clear to me.

From Steve Gubbins I heard already a year ago that a FAA Validation for the EASA was requested.
I have now heard nothing in response to several queries.

Is there any progress on this?

Many thanks

I have now received the news from Steve Lindsley that the EASA approval is now available.

So Bonanza with DFC90 is now also possible in Europe.

Thanks to Steve and Avidyne!
