New math or something?
360 degrees = all the way around, 180 degrees = upside down, yes?
For a guy who is constantly correcting other people's grammar and writing, he's sure got a poor grasp on basic constructs.

Yes, and:I love this gem…
Yup. Hitting wake turbulence that rolls you 10 degrees from inverted is a non-issue.
Hawker stall tests are mostly to verify handling characteristics after the stall trigger is removed/ replaced or is a certain number of leading edge pannels are removed - so you have to do it after C check etc.I just declined my company request to do a stall test on our hawker 900. I have done one in the past when young and dumb. No more. I have been told that the stall test is docile until it is not. Once it is not then it is major and I have been told it may take over 20,000 feet to recover.
Yes hawker stall tests a commonly required. Any time the leading edge comes off. Also the leading edge must come off to do any tks work in the wing.

I think this poorly-conceived image has probably killed people, especially in the form where it's extrapolated and used for "stall speeds."
The load factor is not induced by the turn in this image, but by the application of elevator backpressure. The same load factor would be induced by the same backpressure in level flight.
You're loading the wing with the elevator. There is no load induced by the turn itself.
It causes fundamental misunderstanding of aerodynamics that takes a lot of work to fix. (I've worked to help quite a few people over the years who thought they understood turning aerodynamics and were shocked to find that they didn't.)
I know everyone here knows this, but I want to point out how bad this image (and caption) tangles up people who haven't developed a solid understanding of aerodynamics yet.
You two might need a little privacy...perhaps PM? Facebook? Tinder?Tell me something about yourself, otherwise you're just internet jibberjabber, you're not real.

Ok, excellent call! Mea culpa. You're absolutely right. My wee, addled brain was confused. I think... maybe... I was "thinking" half-way to fully inverted. Probably due to too many beers and oxy deprivation from a long day. But, no excuses! Either way, I was wrong. You are correct. And, I sit corrected.New math or something?

Mirrors are a bitch. Everything is backwards. Very difficult to do a home appendectomy via mirror. Kinda the same reason we should stop seeking to go back to some imagined "past of glory", and instead move ahead, smarter than we were back then. Going backward is only ever going to be a losing proposition - whether civilizationally or appendectomally.I fall down a lot, have been in a couple brawls in years gone by where I shouldn't have been, and just got old, generally, where some stitches (and I did that one time personally - not at all recommended) were required. I try to ignore mirrors, too, with varying degrees of success.
Believe it or not, my worst visit to urgent care was for removal of an embedded tick in a very personal place I could neither see nor excise. I felt badly for the nurse who accomplished the task but more embarrassed for the process required. I hope never to have a tick that requires the same of me in a location such as that, whatever the professionalism of the caregiver
I'm still going to use the quote in different places as circumstances permit, if you don't mind. If you do, I'll respect your preference.
NO. You don't (and you know that you don't)! That's precisely the problem. That's precisely why you scribed your excellent -yet seemingly unnecessary- post.The load factor is not induced by the turn in this image, but by the application of elevator backpressure. The same load factor would be induced by the same backpressure in level flight.

That's actually pretty damned funny. Just sad that you didn't suss it yourself and had to rely on @SteveC to give you your bullets.I love this gem…

I call BEEE ESSS on that. At least the 95% statistical expectation. I'd call it more like, maybe 50%. Kinda off to one side of the bell curve.Woah let's stop the train for a second. I'm not like *entirely* convinced that most working pilots don't understand basic aerodynamics. I mean sure, you definitely get your outliers who treat it as a Dunken-Hines cake mix recipe (follow the directions, press the right buttons, and you get a nice cake, no need to understand how it works). But I'd put pretty good money down that 95%+ of the people I fly with understand in a basic sense that they're "flying the wing(s)".
It's popular and, what, "click-baity" to rail against the dying of Teh Fundamentals, etc. etc., but I haven't really seen much of that on the line, at least to the extent that it's obvious one way or the other.
I *have* seen a fair amount of complacency, and I'm sure I'm guilty of that myself. You (whoever you are) may be as well. But not understanding that the wing stalls when it's loaded up (whichever way the aircraft is pointed relative to the horizon)? Ehhhhh. I can count on one hand (ok maybe two hands) the number of times I've flown with someone who I would even *suspect* of that in *counts on fingers* 30ish years of operating the aviation appliances. Maybe I've just been lucky?
Or maybe this is just a weeee bit of confirmation-bias fueled by watching too much YouTube and a slightly negative attitude regarding These Danged Kids.
OTOH, their music does suck. There's no rational argument there.

For a variety of messed up reasons, I get to interact with the new hires at a particular airline. I'm very concerned. I'm really not meaning to be an arrogant, condescending ass-hat. I just see what see. It's freaking scary.I don't see how someone gets through EET training (for all of its limitations) without understanding how a wing works *shrug*. Maybe I'm not seeing the whole picture, since I mostly fly with people as Old (or Older) than myself, dunno. I suppose it's possible that at the dreaded Regionals (or 135 Charter, etc.) everyone is getting by on luck, but they sure don't seem to be tumbling out of the sky like shot pigeons all over the place.
Fair enough. Guess I'll just be grateful that my yob hires grandpas and grannies. And maybe start sleeping in the basement.For a variety of messed up reasons, I get to interact with the new hires at a particular airline. I'm very concerned.

It ain't "those danged kids". Many of "those danged kids" are terrific. Some few are outstanding and, having just come from real engagement in a good training environment, know more of the minutia than I recall anymore.I *have* seen a fair amount of complacency, and I'm sure I'm guilty of that myself.
