April 3, 20206 yr Hi, I have this problem on some airports. Had it on EKCH earlier and now today i have it on EDDL. I load my TBM900 aircraft and connect to vatsim. Local QNH is 1017. I set the altimeter to 1017 and it shows approx 150ft which is correct. I start Active Sky XP and now suddenly is shows -80ft. To match the real airport elevation which is 147ft i have to set the altimeter to QNH 1027. I close Active Sky XP and the altimeter now shows the correct altitude 147ft. I tried selecting to use VATSIM weather and without VATSIM weather but it didn't make any difference. Anyone have any ideas?
