Hi Nick
It is based on P3D experience with other airports add ons where airport elevation data is conflicting with the mesh or vectors and other problems between your software and other addons like flytampa but so far I am enjoying flying msfs2020 with default scenery and some new addons airports and your airports are fantastic on both P3D and MSFS and the realism it is great although; I preferer not changing the scenery on MSFS, I maybe do later I paid lot of money for the deluxe msfs and I am loving it (just GA airplanes) I am waiting for PMDG to fly the big airplanes!
your Orbx scenery is amazing within P3D , Orbx, and Active Sky make P3D enjoyable

Roland
