In the X650 v2 equipment, which module contains the altitude presssure sensor? I hear that the Auotpilot uses GPS and pressure sensor for altitude hold....is this correct? and, if so, how does it determine which sensor to use?
It does give both a barometric pressure altitude reading and a GPS reading while connected in XAircraft Center. If I had to guess I'd say it takes averages of both readings on the fly for increased accuracy, but don't take my word for it.
