Subject: Pietenpol-List: deadstick flyingGood Shad-- I'm glad to hear that I'm not the only one who has intentionally shutdown an engine in flight. After having our Champ for about 3 years I shutdownthe engine about 2,000' msl over my home field on a weekday when the only one inthe air was me. I did a circling approach and came in high on purpose thenslipped off the altitude to touchdown. I was doing my best Bob Hoover wanna bein a Champ:) I was surprised at how many times it took me to stop the windmilling prop. (Ididn't have a Corvair:))) Kidding ! I stalled the airplane three times to getthe metalprop to stop windmilling. Okay...so that was a fairly tired engine so the compressionwasn't the best to stop the prop quickly. It got quiet quick but it was really a good learning experience in that I reallyneeded to keep the nose much more down to keep my glide speed up than you wouldwith an engine at idle-- surprise number one. Surprise number two is how short your landing roll is---again, with no windmillingprop there is no thrust what so ever to keep you rolling a bit longer on landing.It was dead quiet when the wheels stopped rumbling on the grass. Was a goodexperience. In my mind they should make every Private and Sport Pilot do spins-- to the leftand right and do at least one intentional dead stick landing at an airport witha good long runway. Not kidding-- just like I think every High School Studentshould either have to spend a month in a foreign third world country or go thruboot camp to qualify for graduation. Not kidding there either. Okay-- enough of my rambling. Mike C. in Ohio________________________________________________________________________________

I pulled the same 'stunt' in my T-craft. The surprise to me was not how slowI had to get it to stop windmilling, but how fast I had to dive (and howmuch altitude it took) to overcome compression and start again! Having doneit couple times, and looking back (waaaay back - like 35 years! And itseemed like a good idea at the time, even though I was nowhere near theairport), I'm not sure what useful information I learned.Gary BootheCool, Ca.PietenpolWW Corvair ConversionTail done, Fuselage on gear(13 ribs down.)-----Original Message-----

If you want to try this, let me give you a little tip (learned when I didthe same thing with my J-3 in Texas years ago): Do it over an airport witha long runway and aim for the MIDDLE of the runway for your landing. Thatway, if the glide is a little different from what you expect, you can easilycompensate.Jack PhillipsNX899JP-----Original Message-----

Subject: RE: Pietenpol-List: deadstick flyingI agree with Jack's mention of "aim for the middle of the runway, not the end"when you havea deadstick on your hands. That would translate to aiming for the middle of a farmers field, grassy stretch,or whateveryou are trying to land on. I learned that (especially so in a Pietenpol with all that drag) your 'circle',if you will, ofpotential fields to land in is MUCH smaller in diameter with a dead engine thanwith an idlingengine. Pick something close-- something that is doable with altitude to spare,not where you put yourself in a situation where you're trying to stretch your glide.

You guys that can choose to stop the prop, instead of waiting for the crankshaftto break.......sheesh.I used to do a deadstick aerobatic routine in my stock 1939 Taylorcraft, from 4,000feet, a five turn spin, then loops, barrel rolls, and reverse cuban 8s. Don't try this at home, but it did it quite well.-Read this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 26 Aug 2009 03:24:38 -0400Subject: Re: Pietenpol-List: Fuselage building and material;exelente

I agree with Mike, there are a lot more emergency procedures which should be focusedon in flight training. I would also second Jack's recommendation to practicedead sticks to a good runway. As a line-boy back in High School, I helpeda crew of mechanics in air boats retrieve one of our C-152s out of the EasternEverglades. An instructor shut down the engine around 4,000agl and gave hisstudent until 2,000agl to practice his emergency procedures and accomplish a restart.Well he must have flooded the engine, they could not make it back to theairfield, and they practiced an actual dead stick into the muck of the FL everglades.It flipped, they were fine, and walked several miles to the nearestroad. it made for an interesting 24 hour recovery in air boats!SteveRead this topic online here:http://forums.matronics.com/viewtopic.p ... ______Date: Wed, 26 Aug 2009 10:00:53 -0500
