The author seems to further believe that CAPS is a fix for all sorts of situations, such as pilot disorientation and loss of control at low altitude. These statements do not reassure me. It sounds eerily like pilots who believe that a GPS will perfectly and perpetually solve all their navigation issues forever. |

Since you don't fly a real plane, why do you even care what REAL pilots believe? Real pilots much rather go straight lines to make more efficient time in their flight, but you have no clue what it's like navigating in the REAL world. IF YOU DID KNOW WHAT IT'S LIKE TO NAVIGATE IN THE REAL WORLD, YOU WOULD NOT SAY SUCH AN INCOMPETENT STATEMENT LIKE THE ABOVE. |

Objectivity of such an organization should be considered, but questioning per se isn't an indictment or conviction of wrongful analysis or fact cherry picking. One needs to point out the false factual claims or flawed logic. Especially when I see statements like "... the ultimate safety device: CAPS." That's exactly the kind of attitude that can cause accidents. The author seems to further believe that CAPS is a fix for all sorts of situations, such as pilot disorientation and loss of control at low altitude. Taken in the context of the entire article, the author appears to be using the word "ultimate" in its "final" or "last" meanings. When CAPS is deployed it pretty much _is_ the ultimate or final safety action a pilot can take - after which she becomes (hopefully) a passive floating object. I would agree with him and disagree with you that CAPS is one possible resolution to pilot disorientation and loss of control at low altitude. He doesn't say use of CAPS is certain to succeed in either case - merely that timely deployment has a good chance of working. As to low altitude loss of control: consider a stall/spin on a turn from base to final at 500 ft. Assuming the aircraft immediately (and unrealistically) accelerated to 5000 ft/min (~84 ft/sec) and the deployment had to occur above 200 ft AGL to succeed, the pilot or passenger would have about 3.5 seconds to act. Not much but certainly plausible. But the average descent rate is likely to be half that or less, so more like 7 seconds to react. I haven't tried it, but you could do an experiment and force a spin or stall on final on a normal landing on MS flight simulator and time how long it takes to hit the ground (or pass 200 ft AGL.) I'd be interested in your results. These statements do not reassure me. It sounds eerily like pilots who believe that a GPS will perfectly and perpetually solve all their navigation issues forever. And yet the organization claims that the accident statistics of its members is much lower than single engine GA in general. |

One needs to point out the false factual claims or flawed logic. In this case, there's too much that's subjective about the judgment to prove anything either way. From what I've seen, it looks like Cirrus has more accidents than it should, and it seems that many Cirrus pilots are different from average in lack of experience, lack of caution, or in other ways that make them particularly prone to pilot error. However, the numbers can be cooked and recooked to "prove" almost anything. Even without looking at pilots, one need only look at Cirrus' marketing strategy to be able to predict that it's going to attract the wrong kind of people to flying their aircraft. It's a bit like the flying car I just posted a link about in another new thread. However, the flying car is unlikely to ever become any kind of practicable reality, so there's no risk associated with the hype being built around it. Taken in the context of the entire article, the author appears to be using the word "ultimate" in its "final" or "last" meanings. When CAPS is deployed it pretty much _is_ the ultimate or final safety action a pilot can take - after which she becomes (hopefully) a passive floating object. I read yesterday that the descent rate of a Cirrus with the parachute deployed is around 1700 fpm, far more than a competent pilot could manage by actually flying the aircraft. And the maximum speed for deployment is 133 knots. The parachute was originally installed to get past the fact that Cirrus aircraft behave very poorly in spins. Cirrus marketing turned a liability into an (apparent) asset, which is quite an accomplishment, but not one that I think serves the public interest. I haven't tried it, but you could do an experiment and force a spin or stall on final on a normal landing on MS flight simulator and time how long it takes to hit the ground (or pass 200 ft AGL.) I'd be interested in your results. I don't have a Cirrus, although Eaglesoft supposedly makes a nice one that I've been thinking about (when I have the budget). Since the Cirrus simulation would essentially be a simulation of two PC screens on another PC screen, I have some doubts--it's hard to simulate all-in-one glass panels accurately, unless one has access to the original source code or a great deal of time to work on it. MSFS also is not tops at simulating unusual flight regimes, given its table-based design. I do note that Carenado's Cessnas seem to behave in a spin just as the real aircraft supposedly behave, or at least they are difficult to spin and easy to recover. And yet the organization claims that the accident statistics of its members is much lower than single engine GA in general. That's what I would expect them to claim. It's hard to imagine that they are completely unbiased. Other sources I've visited point out how the numbers can be cooked. In general, I am suspicious of companies that spend too much on marketing. Cessna has been guilty of that a bit in the past and perhaps even today. Beechcraft seems to be much more conservative. It seems that the high end often spends money on quality and then lets the product speak for itself, whereas the low end spends a lot more on marketing to conceal the shortcomings of a product (not just in aviation, of course). |

It seems completely outlandish to me that you wouldn't be able to exceed 1700fpm in flight, but powered aircraft in general and the Cirrus in particular aren't exactly my area of expertise. -- Mike Ash Radio Free Earth Broadcasting from our climate-controlled studios deep inside the Moon |

As usual Mx talks with NO knowledge of flying a REAL airplane hence his trolling continues. He is absolutely clueless. I have FAR exceeded 2000 fpm descent rate (have a video of it on my You Tube channel) practicing emergency descents in a Sundowner. I am here to talk about it and it was completely controlled. Things happen real fast and not for the faint of heart. My research before trying 90 degree bank in a non acro plane can be found at http://discussions.flightaware.com/v...?p=87495#87495 My reaction after doing this emergency descent manuever can be found at http://discussions.flightaware.com/v...?p=87850#87850 The video itself can be seen at http://www.youtube.com/watch?v=dxkiT8gWIQo No access to You Tube where I am at, sooooo going on memory, I provided FARS references on legality of doing this manuevar as acro is not defined by a degree of bank, but requirements for parachutes when WITH passengers (I was solo - no parachute required) is defined by degrees of bank. |
