In P3Dv5, with an airfield on sloping terrain, the jetways and marshallers appear to be set at airfield elevation, which puts them either buried in the ground or floating in the air if they are positioned at a spot where the elevation differs from the base airfield elevation.
The pushback vehicle, baggage trains, and baggage loaders all sit properly on the pavement at parking spots of differing altitudes. The Safedock parking systems can be raised or lowered to accomodate differences in elevation at any particular spot. As more airports take advantage of this new P3D sloped surface capability, we're going to need the ability to set a spot-specific base elevation for the jetways and marshallers...perhaps default to field elevation with the ability to adjust up/down from there.
