Yeah, he thinks he’s found an all new force that everyone else has missed.

Its obviously Coriolis, So all you northerners please be careful when you do your downwind turns down under

The CAA and FAA should do more to dispel this BS. Apparently this guy is/was an instructor with CAA certification. How many more jokers like him out there then? |

Attempts at explaining frames of reference went no where. And before anyone pipes in, vertical lines were not supposed to be corrected for wind, the judges were supposed to allow for the fact that you would drift. |

Just keeping it local, speeds approximate and in knots:
At the Equator: 970kn Earth orbital speed around Sun: 58,000kn Sun orbital speed around galaxy: 447,000kn (Really?) Less local: Galaxy through space: 1,166,310kn So, when you make a 180 in your 50kn glider you change from going forwards at over a million knots to backwards at the same speed. Better lock your hold on those flight controls! ;) p.s. Foregoing a bit of Shiraz induced reductio ad absurdum - did you notice? |

That's gonna be tough. No dealings with the CAA but I would bet long odds that I could easily find FAA inspectors who believe in the downwind turn myth.
Another of his mantras was that if a modification meant an engine delivered more power, it MUST increase fuel burn. "Efficiency" was apparently a foreign concept to him. |

Richard Collins, editor of the US Flying magazine was a believer, writing articles about it.

Actually, after a little googling, I think I defamed Collins- it was J McClellan, also a former Flying editor, who wrote an article full of all the non-science associated with the downwind turn myth.

In the early days I was struggling with S&L in an out-of-trim Cherokee, and was discouraged from "playing" with the rudder trim on the basis that the tendency for it to keep flying one wing down was because of the crosswind...

Ask him this:
Someone should ask him:
"Is there any conceivable air data instrument that you could stick onto an aircraft (or a bird) that would tell you what said aircraft or bird was doing relative to the ground?" "Is there any conceivable air data instrument that you could stick onto an aircraft (or a bird) that would tell you what the wind was doing?" It's astounding the difficulty people have with the concept of frames of reference. |

I pointed out that it's trimmed neutral right now (and physically let go of the yoke to show him) and expected him to realize his brainfart. No, he persisted in trying to convince me that "I'm just making my job harder" being trimmed against the crosswind. I wish I was kidding.

Neither here nor there, but I love birds:
Aren't albatrosses effectively doing wave soaring: positioning themselves in the updraft part of the standing waves that are created when a constant wind blows over an irregular surface? With the irregular surface being the ocean? Constant speed wind striking the face of an ocean wave is very much like constant speed wind striking a mountain ridge: enormous updraft starting from the windward face and extending up and to leeward -- monster downsmashing rotor immediately to leeward of the wave crest / mountain peak. Albatross knows enough to stay in the updraft. |
