Subject: Re: Pietenpol-List: Good information on turning back to the runwayRyan, I am currently flying the dickens out of my buddy's 1947 Aeronca Champ. Itis a great classic, 65 roaring HP and hand prop only. Last flight we did downwindlandings and "I didn't like it so much!" I am getting ready to get my taildragger endorsement signed off by Vern Foster, a 95 year old CFI. My 1947 Bonanza is currently in maintenance, My ammeter is showing nothing, Absolutelyno movement of the needle. We swapped Generators (had one one the shelf)and will look at the meter itself next, The Voltage regulator is last to bechecked, it is a pain, mounted on the firewall way up under the glareshield.Regarding Dr Dave's articles, the same principles apply to Bonanzas, Piets or AeroncaChamps (what I have flown the most lately.) So the same excercises he discussescan be done in any plane. I am not only a grunt but I went to public schools and state universties. My eyestend to glaze over when I look at this level of math. Indeed, I don't do mathin public. Having read several of his articles I tend to scan the math andgo to his conclusions. Dr. Rogers first figures out the aerodynamics of what is being considered usingthis high level aeronautical math. Then he climbs in his plane and goes out andchecks to see if the data matches his real world experience. Then he goes backand polishes his data and his articles. For us Bonanza pilots, he came up with a series of turning excercises to try inthe air. Using these I was able to figure out that I would not try to turn back180 degrees, until I was at almost 1000 feet (fully loaded, hot day roundedup). Even then I was not assured of getting back to the runway, but simply linedup with the runway and in landing attitude.Basically, Go to a safe altitude, Establish a takeoff climb, Chop the throttleand see how much altitude it takes to turn 180 and get set up for landing backon the takeoff runway. What speeds work best?, What about flatter turns vs knifeedge? What about a 90 degree turn to a safe option, what turn works bestand how much altitude is lost? That is the gist of his articles. He explans whycertain proceedures work and why others don't.Blue Skies,Steve D----- Original Message -----
