About the Rockwell 685
The Aero Commander Rockwell 685 is a United States fixed-wing aircraft categorized as a light-twin piston-engined transport. It features a pressurized cabin, a high-wing cantilever monoplane layout, and retractable nose-wheel landing gear, accommodating a crew of one to two alongside an enclosed cabin seating nine occupants.
Developed as a piston-powered variant of a turboprop predecessor, the aircraft is powered by two wing-mounted Continental piston engines with feathering propellers. It received type certification from the Federal Aviation Administration and was produced during the early nineteen seventies, resulting in a limited total production run before retirement.
