No, Kestrel was the basis for Alan K. to get back into aviation after being kicked out of Cirrus for almost bankrupting the company chasing the SSF50. Tim

Mike C. Wow. A pressurized turbine plane has more kinetic energy than a piston single. Who'd have thought ? Surely no one will want to fly a turbine powered plane after this revelation becomes public

Username Protected wrote: Wouldn't the impact energy under the chute canopy in the Cirrus surely be less than the Bonanza? Probably. No one really knows because Cirrus never did a full up system test as they petitioned the FAA to excuse them from that requirement. Part of that argument is that the chute provides no benefit towards any certification requirements. One issue is that the SR series always had the landing gear to absorb impact since it was fixed gear. The SF50 doesn't, the gear could be retracted at impact. So the impact may be more severe. The first customer to pull the chute will become a test pilot. It will be interesting to see what the outcome is. As you noted, the chute doesn't work for a engine failure at low altitude. A second engine does. In that scenario, the SF50 has substantially more impact energy than a Bonanza. Quote: I'd also point out that the Cirrus will be arriving at the destination airport in 1/2 the time our esteemed BT brother will be in his Bonanza, in pressurized, air conditioned comfort. And the twin jet flyer gets there faster, flies higher out of more weather, just as comfortable, uses less fuel doing so, and can handle an engine failure in all regimes of flight with high safety. Quote: oh wait the Cirrus has a computer to keep him from pulling such crazy moves... Oh wait, the computer can make mistakes. Bad logic, bad sensors, bad input data, etc. Read the FSB report, sounds like the computer didn't always agree with the pilots when it comes to stall warning and behaviors. It still freaks me out the SF50 needed a stick pusher. You usually only see that in swept wing jets with dangerous stall behavior. For example, Beech Premier. The pusher exists only because forcing the nose down against the pilot wishes is LESS dangerous than actually stalling. For a straight wing simple jet, it should not have required one, like Mustang and Eclipse. Mike C.

B-52 Mitsubishi MU-300 Beechjet/Hawker 400 F-14 Off the top of my head. Correct me if I'm wrong. I'm pretty sure the SF50 has ailerons.  Nathan

Mike posts plenty of facts which are legitimate points about ways that the SF50 (a small, owner-flown plane) does not meet the same specs as large business jets and airliners. What he misses is that nobody cares.

PC-12 has a pusher, so does the HondaJet.
