Very steep. The bank angle may be quantified: Good grief Larry, you really are an idiot. Of course it can be quatified, but the numbers only tell a minute part of the story. I can categorically state that I can do a 180 with 70 deg bank at VSO 1.2 deadstick and come out the other end in one piece. Can you? Try it using those figures and send my the answer via my Ouiji board. Well I cannot understand you you can load the plane up like that and not raise stall speed beyond 1.2Vs so you must be using a wing drop to acclerate the turn? Do you could just stall out of the turn -but how much height do you loose in the stall and it's recovery? No, you have to lower the nose continuously to offload as you go around the bend. You will end up fairy nose low at the end of the turn alright but you can recover that as you level the wings. The turn is pretty rapid at that speed so you won't be in it too long. It's as about "on the edge" as you can get. It's the only way it can be done unles you have an airplane with an outrageous climb. If you're proficient in spins try it at a bit of altitude and a reduced bank angle. You can increase the bank in subsequent attempts as you become more comfortable. just don't get the idea that this will make you good enough to try it in anger on it's own! Bertie Is that a good description of how Bob Hoover used to fly his engine out performance in the Shrike commander? His energy management routine was one of the best parts of an airshow. Kirk Well, in many ways this is a lot more demanding. he would have had a lot of energy in sotre for that dispaly, doing this, you're relatively low and you have no speed to spare bar what you can make for yourself by getting the nose down. I'm not saying you have to be a flying god to do it, but you do have to be able to do this sort of manuever accurately without even thinking about it, and that isn't part of any syllabus I know of.

"In physics...The scalar absolute value (magnitude) of velocity is speed." Cheers But it's relative to space, not the earth, as I posted earlier. Earth pulls straight down, nothing more. Do this, as we have done many times: Go out and fly on a day when the upper winds are at 30 or 40 knots and get under the hood, do 30 degree banked turns, maintaining a constant altitude and power setting, and see if the airspeed changes. Got to be done over flat land, BTW. Any orographic lift will screw up the altitude. You won't see any performance changes, but the airplane's flight path over the ground sure isn't circular. Try 45 degree banked turns. Try it in a glide. See if you can prove me wrong. Dan |

I know all those languages better than English, which obviously isn't my native language. How many languages do _you_ speak? Nevertheless I know English good enough to know that in general use velocity is synonymous to speed. I don't expect you to agree with me, but maybe you accept an excerpt from the OED: velocity 1. a. Rapidity or celerity of motion; swiftness, speed. 1849 Macaulay Hist. Eng. iii. I. 379 The flying coaches are extolled as far superior to any similar vehicles ever known in the world. Their velocity is the subject of special commendation. c. In scientific use, speed together with the direction of travel, as a vector quantity. So again: If, outside a strictly scientific or technical environment, you choose to use a technical term which has a different meaning in general use than in scientific use, then better advise it. |
