The Cirrus SR22 is a single-engine, originally four and later five-seat, composite aircraft built by Cirrus Aircraft starting in 2001. It is a more powerful version of the Cirrus SR20, with a larger wing, higher fuel capacity, and a 310 horsepower (231 kW) engine. It is extremely popular among purchasers of new aircraft and has been the world's best-selling, single-engine, four-seat aircraft for several years. Like the Cessna 400, but unlike most other aircraft in its class, the SR22 has fixed (non-retractable) landing gear.
The aircraft is perhaps best known for being equipped with the Cirrus Airframe Parachute System (CAPS), an emergency parachute capable of lowering the entire aircraft (and occupants) to the ground in an emergency.
Design and development
The SR22 was certified in November 2000 and is a higher-powered version of the earlier SR20. The SR22 is a low wing cantilever monoplane of composite construction with tricycle landing gear, featuring a castering nose wheel and steering via differential braking on the main wheels. It is powered by a nose-mounted 310 hp (230 kW) Continental IO-550-N piston engine. The four-seat cabin is accessed through a door on each side.
In 2004 the company introduced the SR22 G2 (Generation 2) and in 2007 the SR22 G3 (Generation 3). Both were defined by airframe modifications, G2 by fuselage and G3 by wing/landing gear changes.
In 2013 the Cirrus SR22 G5 (Generation 5) was introduced (there was no G4). Key changes were an increase in gross weight to 3,600 lb (1,633 kg) and a standard five-seat cabin arrangement. The G5 received only very minor changes for 2014 including integrated LED lighting and high performance Beringer brakes.
In 2013 the SR22 and SR22T were the highest selling four-to-five-seat fixed wing aircraft in the world and had been for eleven years in a row.
Cirrus introduced the "SR22 Turbo" in 2006. This was factory installation of a Tornado Alley turbonormalizing upgrade kit installed under a Supplemental Type Certificate. It features twin turbonormalizers and twin intercoolers. Also included with the conversion is built-in oxygen and a Hartzell 3-blade lightweight composite propeller. The weight of the conversion reduces the SR22's useful load. Air conditioning is available with the SR22 Turbo, but this further reduces the useful load. The turbo version has a certified ceiling of 25,000 feet (7,600 m), a maximum cruise speed of 211 knots (391 km/h), and a top speed of 219 knots (406 km/h).
SR22s that were built before 2003 were equipped with traditional analog instruments and 10" Multi-function display (MFD). In 2003 SR22s were first delivered with the Avidyne Entegra primary flight display which later that year became standard equipment. Retrofits are available for the older aircraft that replace the instrument panels with a new one that will include the PFD, a new multifunction display and the installation of back-up mechanical instruments.
On 22 May 2008, Cirrus and Garmin revealed a new cockpit, Cirrus Perspective (by Garmin). Both cockpits were available for a period (Avidyne cockpit was initially standard equipment). Today only the Perspective panel is offered.
At the 2010 EAA AirVenture, Cirrus announced its plans to certify Garmin's system known as ESP (Electronic Stability and Protection) on the Cirrus SR22. It would include advanced flight envelope protection that could stabilize the aircraft with the push of a button, to avoid spiral from developing.
Flight into known icing
The completion of testing for flight into known icing (FIKI) was announced by the manufacturer on 12 January 2009. The equipment change involved installation of a larger fluid tank for the TKS weeping wing system and more areas of the aircraft protected. The new installation was approved by the FAA in April 2009.
An SR-22 was chosen for an 2013 world record attempt by 19-year-old Ryan Campbell to become the youngest pilot to fly solo around the world. On 7 September 2013 he landed back in Australia, making him the youngest pilot to navigate around the world at the time. The SR-22 "Spirit of the Sapphire Coast" was modified by removing three seats and adding a 160 U.S. gallons (610 L; 130 imp gal) fuselage tank for a total of 250 U.S. gallons (950 L; 210 imp gal) usable.
- Original version
- SR22 G2
- Improved variant
- SR22 Turbo G2
In July 2006, Cirrus announced a turbo normalized SR22. Some initial models were identified as Signature Edition SE22 G2's.
- SR22 G3
- Improved variant for 2007 with increased fuel capacity from 81 to 92 U.S. gallons (310 to 350 L; 67 to 77 imp gal), lighter stronger carbon fiber wing spar and redesigned taller landing gear for better prop clearance.
- Introduced as a new model in June 2010, with a ground-boosted Continental TSIO-550-K producing 315 hp (235 kW). The engine has low compression pistons, producing a 7.5 to 1 compression ratio to allow the engine to run on lower octane fuel, 94UL. The SR22T has an increased maximum cruise speed of 214 kn (396 km/h), and empty weight of 2,348 lb (1,065 kg) and a maximum operating altitude of 25,000 ft (7,620 m). This model also has a decreased useful load of 1,052 lb (477 kg) and reduced range of 1,046 nmi (1,937 km). This model is also equipped with a Hartzell three-Blade Lightweight Composite Prop.
- Version with a Tornado Alley turbo-normalizing kit added to the Continental IO-550-N engine producing 310 hp (231 kW).
- SR22 G5 and SR22T G5
- On 17 January 2013 Cirrus Aircraft announced the fourth generation of the SR22 and SR22T (skipping G4 as a designation for the new version of the aircraft). New features include the maximum takeoff weight increased by 200 lb (91 kg) and the previous optional split 60/40 split back seat, ADS-B transponder and Garmin GFC700 autopilot are now standard. The wheel pants were redesigned and include an access door for the inflator valve. The aircraft ballistic parachute has also been improved and includes a larger canopy to account for the higher takeoff weight along with a more powerful rocket. The rocket is fired by a failsafe electronic ignition and can now be deployed at 140 knots (formerly 133 knots). Earlier versions used pyrotechnic rocket ignition. The speeds at which flaps can be deployed have been increased to 150 knots for the first notch, 110 knots for the second notch of flaps, with an additional 3.5 degrees of extension. Fuel burn is slightly increased at cruise speeds, rate of climb has been reduced, liftoff speed has increased to 80 knots from 72 knots and stall speed has increased to 60 knots from 58 knots.
Aircraft type club
The aircraft is popular with air charter and small air taxi carriers as well as private individuals and companies. The largest current dedicated fleet operator is ImagineAir, which commenced operations in 2007. SATSair was formerly the largest operator with 26 aircraft; it commenced operations in 2004 and went out of business in 2009.
Accidents and incidents
Between 2001 and May 2014 147 US-registered Cirrus SR22 aircraft crashed, resulting in 122 fatalities.
In 2011 the accident record of the SR20 and 22 was the subject of a detailed examination by Aviation Consumer magazine. The review concluded that the series has an overall accident record that is better than average for light aircraft, exceeded only by the Diamond DA40 and DA42. However its fatal accident rate is much worse at 1.6 per 100,000 flight hours, placing it higher than the United States general aviation rate of 1.2 and higher than the Diamond DA40 (0.35), Cessna 172 (0.45), Diamond DA42 (0.54), Cessna 182 (0.69) and the Cessna 400 (1.0), despite the SR22's full aircraft parachute system.
By 2014 the accident rate had been dramatically reduced, with a 2013 fatal rate of 1.01 per 100,000 flight hours. This was attributed to better training, particularly in when to deploy the ballistic parachute system.
