I ran into a good one out of the blue yesterday.. Fired everything up and the captain side connects fine. The FO side connects fine as well and then the baro setting slowly decreases from the actual (30.00 for example) down to 25.85 IN and stays there. The MCP doesn't change the setting when I play with that. It happens at all airports that I select.

Any thoughts?

Cheers,

Sounds like an external rotary decoder keeps sending negative baro knob delta values to PSX, i.e. it keeps rotating the baro knob on the F/O's EFIS control panel. Is the virtual knob on the PSX graphics rotating even when 25.85 is reached?

That's what it was.
