Might make some small difference due to inertia in a big plane, but only if
you're changing directions.

You were taught wrong.

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.

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.

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.

Oh, excellent point. Absolutely on the head of the nail!

All those clean break stalls were with someone in the other seat.

He's right, you know... And I'll bet you doubting Thomases aren't aware
aircraft in the northern hemisphere only spin clockwise. It's called the
coribolis affect.

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?

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.

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.

There is no "additional air across the wings" if you're going upwind.

To a pilot, altitude is like money - it is possible that having too much
could prove embarassing, but having too little is always fatal.

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.

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.

Impressive. How many stalls have you done in DC-8s and L-1011s?

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