The VRP is really for FlightGear only. We know where the CG is and everything else is relative to that. We explicitly calculate the offset from the CG to the gear contact points during the ground reactions calculations, so we do know (or can determine) the Z _offset_ of the gear contact points below the CG -- which, in turn, would allows us to calculate where the CG would need to be placed to make sure the gear would be above ground. If the airplane is on a steeply-incline triangle near the edge, all bets are off.
