If you can help it, do not change view while on the ground. When changing view, this causes a scenery reload in FS. The elevation data of the airport is reloaded, and this can cause a change of the level of the ground.
If you can manage, stick to one view while on the ground (cockpit view).
Some data in the aircraft.cfg file is editable concerning contact points. I've had a go at this but never got it to work properly.
