Remarks:

Designed by Al Mooney, the M20 was his 20th and most successful design. Over the past 60 years, the M20 series has seen numerous variations, starting with the wooden-wing M20 and M20A models in 1955, and culminating in the M20V Acclaim Ultra, which debuted in 2016. Throughout three production runs, over 11,000 M20 aircraft have been built, with the latest production run ending in 2019.

In November 2008, Mooney halted production due to the late-2000s recession but continued to provide parts and support for existing aircraft. After receiving Chinese investment following a company purchase, production resumed in February 2014. Since then, Mooney has released two additional M20 models.

Turbocharging came to the M20 series in a similar fashion to Piper’s Arrow in the late 1970s. Mooney replaced the durable Lycoming IO-360 engine of the 201 model with a fixed-wastegate version of the Continental TSIO-360. Mooney’s engineers opted for the Continental six-cylinder engine over a turbocharged IO-360 due to concerns about the reliability of turbocharged four-cylinder engines, which had shown poor performance in aftermarket turbo systems added to M20s in the 1960s and early 1970s. Additionally, Continental’s competitive pricing made the decision straightforward.

The Mooney 231 delivers excellent performance in exchange for additional power-management workload. At 8,000 feet, the turbocharged M20 reaches 166 knots true airspeed, slightly outpacing the 201. However, the extra 10 hp only marginally compensates for the increased cooling drag and weight of the 231. The performance advantage becomes clear at 12,000 feet, with the M20K achieving 173 knots true at 75% power and 163 knots at 65% power. True airspeeds continue to increase with altitude, reaching 188 knots at 75% power and 178 knots at 65% power at the 231’s certified ceiling of 24,000 feet. The namesake 231 mph (200 knots) top speed is attainable at full power, 14,000 feet, and a fuel flow of 24 gph, though this is not a practical everyday cruise setting.

Weight also impacts the 231’s performance, with an expected increase of about one or two knots for every 100 pounds below maximum gross weight. Fuel flows are consistent at 12.7 gph at 75% power and 10.9 gph at 65% power.
