What causes this...have no clue

I have this airport KINT...see pic 1... I just installed p3dv5 and i have the same thing happening. See pic 2. I do not have Orbx..FS Aerodata installed and i see this undelating terrain in most of the default airport KTEB included. Is it me or a setting or what.



P3D v5 has a much higher res terrain. You need to basically blend the airport flatten with the surrounding terrain by creating sloped ground polys in ADE and editing the verticies.

Generally right clicking "Place aircraft here" then selecting the individual vertex at that position and click "Set altitude to Sim" or something like that.
