I added an optimization at one time that did this as a 'side effect' but those that were using FlightGear as a training device to land on aircraft carriers convinced me <us> to revert to the previous method. I am not really sure how I did this anymore and I didn't keep the code but perhaps it still lives in the CVS ??
