Checkboard said: You can't set both needles to the same ADF box, there is no need to design in this functionality.
Sure you can set both RMI needles of each RMI (LH and RH) to one ADF, if there is only one ADF installed in the aircraft and both RMI's are connected to that ADF, which is the case in our aircraft!
We still didn't really find the problem....:-) I think I will follow L-Bands advice, which seems to me to be the most convincing answer
"that the follow up resolver is u/s in the 360 quadrant however ok in the 90/270 quadrant.
Tune in the same station and do a 360 and see what happens".
Anyway thank you all...maybe someone has had the same problem and really knows about the answer.
Cheers....
