Might make some small difference due to inertia in a big plane, but only if
you're changing directions. You were taught wrong. mike regish "Jack" wrote in message nk.net... Cause if you know what addition air across the wings does for an aircraft, than you will also realize that stalling an aircraft into the wind will take a moment longer. I was taught that when I got my license, and really learned it with a DC-8 and furthermore in an L-1011. It doesn't change the stall speed as indicated. "mike regish" wrote in message . net... I'm curious as to why you would think going with or against the wind would make any difference. The plane doesn't know which way the wind is going. It makes its own. mike regish "Jack" wrote in message nk.net... I just recently had a BFR in a 172. I honestly couldn't get it to stall. We were at 5k ft and departure stall and power off, she just wouldn't break. That was that airplane, halfway into attempting a third stall "with the wind" this time I lost all radios and was forced to make a precautionary landing. We returned. That night I took a different 172 up, and tried the stall again, that one broke easily into and with the wind. So in answer to your question, I don't know. It may very well be airplane specific. But like you, I had the stick in my gut everytime, and one plane wouldn't break, and the other did. Heck, I almost had a spin going with the second airplane on one attempt.

It's called the coribolis affect. |

ahh.. the dreaded down wind turning stall..
"David Brooks" wrote in message ... "karl gruber" wrote in message ... ****** attempting a third stall "with the wind" this time****** ******that one broke easily into and with the wind****** Where did you dig up this "instructor" for the flight review? You were only along as a victim of his painful ignorance. Steady state wind has no bearing on stalls---none---zero. I, I gottit. If you fly with a strong tailwind, the pilot will sense the groundspeed, have an impression of a higher (mumble)speed, and instinctively pull back that much harder in an attempt to get down to "stall speed". No? No, I gottit. The problem with stalls is that you are spending too much time with limited forward visibility. With a strong headwind, you can just about hover, and aren't instinctively pushing the nose forward all the time to check for approaching mountains. Or other airplanes, doing the abovementioned tailwind stalls. No? -- David Brooks |

My wife's 172b won't stall either. It just runs out of elevator with a forward
CG. Tough to do full stall landings. It just "plops" in. If you trim it in the wrong direction you will have more elevator surface but you essentially will be pressing the tail down with raw muscle. I put a 60lb bag of sand in the baggage and it became a new plane. Even her instructor commented how much nicer it lands. The elevator just needs a little help. Jim |

You are all correct, I think.
But When doing rate of climb tests or glide polars it is best to do them crosswind. Windshifts with altitude cause the data to look like a Z as you pass through such a shift. The climb or descent rate will be constant, then shift, then back to the same rate as things stabilize again. You can not see this worth a darn in the cockpit, unless it is quite strong. At which time you'd be discarding the data anyway because it's too bumpy.

I thought that's what he meant. Wasn't sure if "addition air" was some new
term. Amazing the kind of crap knowledge they'll let you fly an airliner with-if he actually does, that is. mike regish "G.R. Patterson III" wrote in message ...

The only thing that determines when a wing will stall is AOA. Steady state
wind has no effect. A wing will stall at the same angle of attack. Every time. Phil "Jack" wrote in message nk.net... I just recently had a BFR in a 172. I honestly couldn't get it to stall.

(I guess that happens all the time to airliners in 180 kt winds at FL350 when they turn downwind... ;^) |
