D180 strange readings

[jbrady]

About to move the RV-8 to the field for wing fit. Powered up today in the workshop and the altitude says 30,000ft, IAS 380kts and OAT -48! It was normal last week! Any offers for a place to start fault finding?

sounds like a plugged static line but the OAT is a separate issue. Try lightly blowing out the lines out with all gauges disconnected so you don't cause damage.

Do pop off the pitot and static lines to make sure nothing is going on there. If that doesn't change things, we'll probably need to see the unit. In that case, give our support team a call at 425-402-0433 or support at dynonavionics dot com for further help.
