Gulfstream Aerospace has begun the flight-testing phase of its Enhanced Vision System (EVS) in preparation for imminent FAA certification flights. Final certification of the EVS is expected by the third quarter of 2001. “There is a lot of demand for the EVS system,” said Mike Mena, Gulfstream’s EVS programme manager. “We’ve sold about 35 Enhanced Vision Systems for retrofit installation to date, although this number does not include the systems installed on the Gulfstream V-SP.”
