SR Aircraft Series

Cirrus SR (Single Reciprocating) Series aircraft are designed around composite technologies with Cirrus Perspective by Garmin digital flight displays and modern avionics as standard equipment. The aircraft are all electric - no vacuum systems are used. Redundancy is provided by dual batteries and alternators. The SR22 is also available with TKS anti-icing equipment which enables flight into known icing conditions.

The aircraft incorporate other unusual design elements. All Cirrus aircraft use a mechanical side yoke instead of the traditional yoke or stick flight controls. The aircraft also use a single power lever that adjusts both throttle and propeller RPM via a mechanical cam actuated throttle and propeller control system. Construction is dominated by the use of composite materials, although traditional aluminum is used for flight control surfaces.

The Cirrus SR22T is powered by a Continental TSIO-550-K turbocharged engine. Turbocharging allows the engine to maintain maximum power at higher altitudes while increasing the maximum operating altitude to 25,000'.

Other manufacturers and the aviation press widely ridiculed and spoofed many of the marketing terms, but Cessna built and sold more aircraft than any other manufacturer during the boom years of the 1960s and 1970s. Cessna marketing terminology includes:

Cirrus Airframe Parachute System (CAPS) These were the large Fowler flaps Cessna introduced on the 170B in 1952, replacing the narrow chord plain flaps then in use.

The Cirrus SR series (SRV, SR20 and SR22) aircraft are equipped with the Cirrus Airframe Parachute System (CAPS), developed by Ballistic Recovery Systems, a ballistic parachute deployed from the back of the aircraft. In many emergencies, the system allows the entire aircraft to descend safely and has been credited with saving 95 lives.[62] Cirrus was the first manufacturer to receive FAA certification for production aircraft with ballistic parachute systems. The parachute system was accepted by the Federal Aviation Administration as an equivalent level of safety and complete spin testing was not required by the FAA.

Suitable Triple R Cirrus Aircraft

Cirrus SR20

The SR20 was first flown on 21 March 1995 FAA certification was achieved on 23 October 1998 Hundreds of SR20s have been sold since the first was delivered in 1999. As of December 2012 over 5,000 Cirrus aircraft had been delivered.

One of the major selling points for the SR20 is its by Garmin Cirrus Perspective avionics suite with dual 10-inch (250 mm) or 12-inch (300 mm) screens: one primary flight display (PFD) and one multi-function display (MFD). This provides all standard communication, navigation (GPS and conventional VHF), and surveillance (Mode S transponder) functions. Other avionics features include in-flight weather information and TCAS-like traffic information.

The SR20, like the faster SR22, is equipped with the Cirrus Airframe Parachute System, a large parachute which can be deployed in an emergency to lower the entire aircraft to the ground safely.

On 1 June 2004, the SR20 became the first aircraft to achieve the new European Aviation Safety Agency certificate for aircraft imported into the European Union.

In 2004 Cirrus introduced the SR20 G2 (Generation 2) and in 2008 the SR20 G3 (Generation 3). Both were defined by airframe modifications, G2 by fuselage and G3 by wing/landing gear changes. Since 2011 simply "SR20" has been used.

Cirrus SR22

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.

Turbocharged models

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).

In 2010, a new model was introduced, the SR22T. This used a new engine, the Continental TSIO-550K that produces 315 hp (235 kW) with a 7.5:1 compression ratio and will run on 94 octane fuel.

Glass cockpit

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).[15] Both cockpits were available for a period (Avidyne cockpit was initially standard equipment). Today only the Perspective panel is offered.

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.
