Cessna 172 RG (Retractable Gear)The Cessna 172 RG is a four seat, high-wing, single engine “complex” aircraft, powered by a 180hp engine with a constant-speed (variable pitch) propeller. The landing gear is also retractable which makes it faster than the fixed gear Cessna 172. This complex and high performance aircraft is used by many flight schools to train students seeking their Commercial Pilot Certificate, Instrument Rating, or Flight Instructor Certificate/Rating.
