It is amazing how many post that topic got.
IAS - Indicated Air Speed, is the speed of the air over the wing.
Ground speed is the speed of the air craft across the ground.

If a flyer is relying on their vision to judge airspeed by watching how fast the aircraft is moving over the ground, it would make sense that on a downwind turn the airplane would appear to be going faster, and they may compensate by slowing down and thus decreasing the airspeed and cause a stall. I think many flyers choose to use telemetry with IAS to avoid this issue.
A pilot in an aircraft has the instrumentation and has no excuses for stalling in a downwind turn.

Had a guy tell me the other day that his plane unloads so much more going down wind......you can hear it!

How about this.....stall speed is a myth. Its one speed in a given configuration. What really matters is stall angle. You can stall in any direction, even going straight down.

I wonder whatever happened to Tracy. Went into orbit with a celeb on a starjet perhaps?
maybe he is the brains behind Elon musks phallic rocket?
So many possibilities!

Well, he hasn't posted here under the PilotDude57 username since December of 2018.

For those interested, some good stuff in this thread: http://www.rcuniverse.com/forum/fb.asp?m=3745542

I thankfully missed the entire glasscat saga. As the originator of the Downwind Turn Myth thread though, I was shocked at the vitriol from some who refused to let go of their misperceptions. I was even more shocked to see the myth actually defended by a long time professional pilot and regular contributor to a popular publication - someone who should know better.

It’s no wonder then that so many in this hobby are understandably confused, when even highly trained, long-time professional pilots sometimes still labor under and spread such misinformation.

“Common Sense” and intuition are powerful factors here, and the myth that turning into or away from the wind would have an effect on flight performance is so naturally intuitive that I am 100% certain many will defend it eternally, no matter how factually incorrect. I wish I had the ability to take true believers to work with me. There’s nothing like turning an an airplane - one with a 20 knot stall margin and no extra thrust available- repeatedly into and out of a 150 knot wind (common jetstream speeds) without falling from the sky to dispel one’s intuitive notions in favor of scientific fact.

Glad to see you still around HighHorse. I must admit I enjoyed that thread lol. I work with some of the smartest people in aerospace (NASA) , and I see some what you describe.

LOL. That’s a new wrinkle in a topic I thought was long exhausted! Maybe he’s onto something though. We should start a new thread to explore Doppler effect on stall speed?
