Pneumatics Question

. *Replaced the connector this year.

- the VariCalc has connections for all three lines; the Winter
mechanical connects to TE and capacity. *A problem in static shouldn't
affect both instruments.

Faulty multi-connectors can also cause your described symptom as well.
Check the O-rings well, and silicone grease is your friend.

Hmmm, this puts possible tailboom static issues back on the map and
your VariCalc could be cross-talking that or an internal pitot leak
error to your Winter. Run it once with cockpit static before getting
too fancy with time consuming ground testing. It's real easy and you
get to fly... Your vario isolation test will also be useful here, I
suggest unhooking (plug loose lines!) the VariCalc first.
