2011 Cirrus SR22T: Commemorating 10 Years Of GA Innovation
Cirrus refines the SR22T with a 2011 Limited Edition
The Perspective avionics system features synthetic vision as well as an infrared Enhanced Vision System. Reminiscent of a high-end sports car, the red, white and black leather interior, with a leather side stick, is special for the limited-edition model.
Walking around the airplane, Goble shows me other refinements that include the Cirrus wing. The wing features a discontinuous leading edge that visibly divides the wing into inner and outer sections. NASA research originated the design that works by varying angle of attack: The outboard section of the Cirrus wing flies with a lower angle of attack than the inboard section. When the inboard section—which produces much of the lift—stalls, the outboard section keeps flying, allowing aileron control throughout the stall.
Goble also explains that the SR22T's TKS-based ice protection allows the airplane to be certified for flight into known icing conditions (FIKI). This added milestone in Cirrus' vast collection of innovations adds even more utility to an airplane that's already known to be a great cross-country machine. The FIKI modifications on this new SR22T are more than just the "weeping-wing" anti-ice system. When activated, the FIKI system coats all the flight surfaces, including the vertical stabilizer and elevator tips. The system incorporates ice lights that illuminate wing surfaces in low light, windscreen nozzles to assure the pilot an ice-free view on approach, backup pumps and filters, and a range and endurance display on the MFD. The FIKI system provides 150 minutes of endurance at normal flow, 75 minutes at "high," and a new "max" rate of 37.5 minutes at maximum secretion for very heavy buildup.
