So I powered up my aircraft avionics bus for the first time. Everything comes to life, although the D120 does a lot more flickers and jumping around than the D100, but it all started. The D100 has fewer connections to think about I guess, no compass yet.
Symptom:
I noticed a slight but definite "click" sound, which seemed to be coming from inside the D120, a single click perhaps every 6 seconds or so - in a regular pattern. All indications of the D120 looked to be what I expected to see, but I was worried I was about to damage something expensive so I flicked it all off.
Question: Is that clicking sound a normal operational sound, or is something wrong?
Thanks
