Of course not, but my understanding is that the SR-22 design makes
normal spin recovery very difficult, and that it doesn't meet the FAA designation for spin-resistant, as defined: "the airplane may be demonstrated to be spin resistant by the following: (i) During the stall maneuvers...the pitch control must be pulled back and held against the stop. Then, using ailerons and rudders in the proper direction, it must be possible to maintain wings-level flight within 15 degrees of bank and to roll the airplane from a 30-degree bank in one direction to a 30-degree bank in the other direction; (ii) reduce the airplane speed using pitch control at a rate of approximately 1 knot per second until the pitch control reaches the stop; then, with the pitch control pulled back and held against the stop, apply full rudder control in a manner to promote spin entry for a period of 7 seconds or through a 360-degree heading change, whichever occurs first. If the 360-degree heading change is reached first, it must have taken no fewer than 4 seconds. This maneuver must be performed first with the ailerons in the neutral position, and then with the ailerons deflected opposite the direction of turn in the most adverse manner. Power and airplane configuration must be set in accordance with Sec. 23.201(e) without change during the maneuver. At the end of 7 seconds or a 360-degree heading change, the airplane must respond immediately and normally to primary flight controls applied to regain coordinated, unstalled flight without reversal of control effect and without exceeding the temporary control forces specified...and (iii) compliance must be demonstrated with the airplane in uncoordinated flight, corresponding to one ball-width displacement on a slip-skid indicator, unless one ball-width displacement cannot be obtained with full rudder, in which case the demonstration must be with full rudder applied." According to an AOPA writeup, Cirrus requested an exception to FAA spin resistance/recovery requirements by proposing the ballistic parachute as an equivalent recovery device. Consequently, any problems with using standard spin recovery techniques have been paper-worked over. I understand that most unintentional spins take place at altitudes below realistic recovery altitudes anyways, but as PIC, it's my decision whether or not I want to fly an aircraft, and as a buyer, it's my decision on whether or not I like the 'whole package' for a plane. I'm not trying to convince people that the Cirrus is evil, far from it. Like I said, it's a great looking plane with a lot of very nice features. That said, it doesn't meet my _personal_ criteria for safety yet. Hey, give me 10 years and I might change my mind, but I'm not sure how my personal decision not to buy the aircraft can be construed as an attack on the Cirrus community, much less an example of 'badthought' that must be corrected. |

Sure, I fly at night. Again, why does my personal decision not to buy
the plane agitate you? |

You base your "personal decision" on the fact that the parachute might need to be deployed for spin recovery. Yet you fly at night. The likelihood of an engine failure exceeds the likelihood of an unintentional spin at a recoverable altitude. Do you carry night vision equipment? Get it now? moo |
