If it uses barometric height, does it > (can it) compensate for changes in QNH pressure? Barometric height if available. Yes, we can compensate QNH settings. After a short discussion we decided that we don't want to use the barometric altitude that the B500 gives us due to the big error margin. GPS altitude is more precise in this case. This means that the "H Baro" infobox will stay at "---" when a B500 in connected. Sorry about that, but I guess you also prefer no data over wrong data... >> 3) B500 TAS/IAS: The indicated airspeed was also bugged.
