By approaching LDZA in the PMDG B738 in FSX I noticed that the elevation of the airfield in the FMS was 403 ft., while in the scenery (RFscenery builders LDZA) the elevation of the field is 353 ft., and also in real (I checked this in SkyDemon because in real life I’m also a pilot).
Consequence: at 50 ft. above groundlevel the AP disconnected because the FMC asumed I touched the ground!
How can I change the elevation in the Navdata?
