Beechcraft 60 Royal Turbine Duke. (TVSA) Argyle Int'l Airport, St. Vincent & Grenadines.

The Beechcraft 60 Duke is an American-built twin-engine fixed-wing aircraft created by Beechcraft. The aircraft has retractable tricycle landing gear and a pressurized cabin. The two piston engines are turbocharged and the turbochargers also pressurize the cabin with bleed air. Royal Turbine Dukes have been modified by Rocket Engineering of Spokane, Washington, replacing the Lycoming reciprocating engines with Pratt & Whitney Canada PT6A-21 or -35 turbine engines. The modification increases fuel capacity by 28 gallons and the maximum useful load by 400 pounds. The take-off length required is shortened by over 1,500 feet to only 1,000 feet and the landing distance is reduced by over 2,000 feet to only 900. The maximum rate of climb is increased from 1,600 feet per minute to 4,000 feet per minute, reducing the time to climb to 25,000 feet from 25 minutes to 9 minutes. The cruise speed is increased to 290 knots at 29,000 feet. The modification does have some disadvantages as it increases fuel burn from 56 gallons per hour to 66 and lowers the certified ceiling from 30,000 feet to 28,000. The supplemental type certificate was issued on May 12, 2006.
