The Rockwell Commander 685 is a turbocharged high-performance piston-powered airplane designed to meet the business requirements of room and speed normally found in propjet aircraft. The seven- to nineplace 685 is powered by twin turbocharged 435-hp Continental engines with Hartzell constant-speed fullfeathering three-blade props. It can cruise at speeds of 255 mph at 24,000 feet. Its cabin can be arranged in no less than 12 different ways and can maintain sealevel cabin pressure at altitudes up to 9,000 feet. The Commander’s high wing, sturdy landing gear, and 75-knot stall speed allow it to operate from short unimproved strips. With 322 gallons of fuel, the 685 has a range of 1,731 miles with a 45-minute reserve. Its simple fuel system requires no crossfeeding. All fuel feeds into a central fuselage tank.
