About the Cirrus Aircraft SR20

The Cirrus SR20 revolutionized general aviation when it entered production in 1999 as the first certified aircraft with an integrated whole-airframe parachute system, the Cirrus Airframe Parachute System (CAPS), designed to lower the entire aircraft and occupants safely to the ground in an emergency. Built by Cirrus Aircraft in Duluth, Minnesota, the SR20 is a four-seat composite single-engine piston aircraft powered by a Continental IO-360 producing 200 horsepower, offering a cruise speed around 155 knots and a range of approximately 800 nautical miles. Its side-stick control, glass cockpit (Avidyne Entegra or Garmin Perspective avionics), and modern safety features made it a landmark design that challenged the decades-old Cessna and Piper training fleet paradigm.

The SR20 became the best-selling four-seat aircraft in its class and served as the foundation for the higher-performance SR22, which shares the same airframe and safety philosophy. With a service ceiling of 17,500 feet and a maximum takeoff weight of 3,050 pounds, the SR20 occupies the light end of Cirrus's product line, popular with flight schools, owner-pilots, and as a trainer for transition to the SR22. Its stall speeds (57 knots in landing configuration and 65 knots clean) and never-exceed speed of 200 knots define a forgiving yet capable envelope for both training and personal cross-country flying.

SkyMeter has tracked flights across airframes and operators over routes, with the largest observed operator.
