After problems with carbon fouling in compressor vanes, the Eclipse 500 was limited to 30,000 feet, a fuel-inefficient altitude that saps its range. But now, says the company's Mason Holland, Pratt & Whitney has come up with a fix that involves a new burner can design. Eclipse's Ken Oden told us this week at AirVenture that the Pratt modification will extend the EA500's range to beyond 1,000 miles with NBAA reserves.
