16.2.3 Circle of Uncertainty
The Circle of Uncertainty depicts an area where the ownship location is
guaranteed to be when the aircraft location cannot be accurately determined.
The area of the Circle of Uncertainty becomes larger as GPS horizontal accuracy
degrades and smaller as it improves. The Circle of Uncertainty is shown only
when the aircraft is on the ground. The Circle of Uncertainty area is transparent
so that features within it may still be seen.
