Well I asked a while ago for callibrating the pressure why there couldt filled in negative units for height I had to subtract 17 meters for getting the right relative/seapressure for getting it right according METAR stations atm I live virtually 7 meters below sea leavel (some really do here live below sealevel but I’m 10 meter above sealevel in real. I better couldnt make this adjustments as I read your reply ? In that case WF should have mentioned that CL should take care in the coming time that I should need to adjust my offset to sealevel.
The question was over here and a day later it was possible to enter negative values for my altitude.
