The way I understand the procedure works is this; right xwind *from the front
quarter* you turn into the wind (elevator neutral). Right xwind *from the rear
quarter* you turn away from the wind (with down elevator). Left xwind *from the
rear quarter* you turn away from the wind (with down elevator). Left xwind
*from the front quarter* you turn into the wind (elevator neutral). By "turn" I
mean turn ailerons. Perhaps you found yourself with a cross wind coming at you
from the rear. That would explain your instructor's reaction. But I must tell
you, I'm a student with fewer hours than you, so please triple check on this!

You CFI is wrong. Keep the proper crosswind inputs while
taxiing (based on where the wind is relative to you at
the instant) as you turn the aircraft move the controls to
the appropriate position as the relative wind shifts.
Your instructor must be a real hoot in a taildragger.

If your instructor tells you to put the takeoff control
settings in on taxi to you don't have to change them, that's
wrong.
If you had the yoke turned towards the wind with a tailwind
you were wron.

The difference is that when landing the wind is from the front, but when
you turned around it became a quartering tail wind.
The way I learned it is: Tail winds are bad...dive away from them.
Head winds are good...climb into them.
(This is when taxiing on the ground of course)
What this means is that with a quartering tail wind turn the wheel away
from the direction the wind is from, and push it forward. With a quartering
headwind, turn the wheel towards the wind and pull back.
Some textbooks do not mention pushing the wheel forward with a tail wind
except in a trail dragger. Does anyone with more experience know if this
will help or hurt in a tricycle gear plane?

With the wind coming from behind the tail, ailerons AFAIK are turned
*downwind,* because they are acting "in reverse" and you need to keep the
upwind wing down. OTOH the wind would need to be exceptional before it would
roll an aircraft at taxy speeds on the ground - so aileron position is
probably not the main concern. YMMV depending on aircraft type. Elevator
position is more complex, because the propwash may be stronger than the wind.
I'll usually keep it neutral unless the tailwind is extremely strong. A
strong (>25Kts) tailwind is "interesting" in my taildragger, because it's
difficult to hold the controls in any position! Stick and rudder forces are
extremely high, and even using both hands the stick gets snatched this way and
that. The tail gets pushed around quite a bit, so I avoid congested areas!
I'll take grass whenever I can in these circumstances so that I can use power
to advantage. If things get a bit out of hand, a counter-intuitive "gunning"
of the throttle will usually supply enough rudder and elevator authority to
correct.
When taxying or after roll-out with a X-wind, a turn *downwind* gives better
control, because it makes aircraft try to roll into wind. (On the ground, an
aircraft rolls towards the *outside* of the turn).

You get a feel for it...as the airplane begins to
accelerate and the ailerons become more effective you'll
feel it start to bank towards the wheel (and you'll get
used to the feed back through the yoke). Just keep
the wings level and everything will be fine.
No, when the downwind wing wants to come up you let it. You should be taking
of in the same sideslip configuraion that you'd use landing in a cross wind.
Rudder to keep you lined up, bank to keep you from going sideways. Get a litte
tailwheel time you'll understand real quick.
It still applies, although it's easier to flip over a plane with conventional
gear.

Just remember the old mantra... Dive away and turn into... If the wind is
from the rear aileron and rudder inputs should be to "dive away" from the
wind and of course when it is a head wind it is turn into, or toward the
wind.
Roger
Do it in a trike as well!
Both types react the same way -- it's just more critical in a taildragger,
as the CG is behind the main gear.

Another clue (before any banking tendency becomes apparent) is that the
plane will start to "hop" or "jiggle." When that starts to happen, back off
the ailerons a bit. If is smooths out, then you had too much aileron in.
If the instability gets worse, crank more aileron back in, and wait a few
seconds before trying the reduction again.
You'll get the feel of it after a few trials.
Most people have the opposite problem -- not rolling in full aileron after
initial touchdown.
I was taught STEER into a headwind, ie elevator neutral, rather than climb.
The "climb in to a headwind, dive away from a tailwind" phrase comes
from the days of yore when most GA a/c were taildraggers. In addition to
keeping the wind from lifting your wings, you also wanted to keep your tail
on the ground so that you can steer. Thus, the "climb" and "dive" part.
On tricycle gear a/c, you are correct in that the "climb" part isn't quite
as important when dealing with a headwind. However, it's not a bad idea to
do since if you don't pull back a bit on the yoke while taxiing, the elevators
tend to drop in to a dive position which is bad in a headwind and could
potentially result in a prop strike.

No! Even with a fully deflated nose oleo, I am not aware of any trike that
will suffer a prop strike. You would have to lift the main gear off the
ground to do that. But, having said that, most trike POHs specify neutral
elevators for taxiing with a headwind component. You don't want to lift the
nosewheel off the ground in a gust, as there goes most of your steering
capability.

Hi Mike,
If the wind is from the front, drive into it;
if it's from the back, dive away from it.
At least it works for me.
Mark D Jones CFII

Left quartering headwind: aileron up on left wing and neutral elevator.
Left quatering tailwind: aileron down on left wing and down elevator.
Right quartering headwind: aleron up on right wing and neutral elevator.
Right quartering tailwind: aleron down on left wing and down elevator.
You used the term 'put the aileron controls into the wind' is unclear, it
would be better to describe and think of the actual control surfaces and how
it interacts with the wind.
You should ask your CFI and have this explained to your satifaction and
understanding. DON'T LET IT GO. You someday would have to deal with it on
your own and you better learn it now.

I typically taxi with full up elevator in a 3100# Debonair, except when
it's really
windy. I can get the nose gear off at about 40 -50 MPH
One day I had parked the Debonair in front of the terminal and a number
of us were
doing a little hanger flying when I noticed a squal line headed our
way. (Lake effect
snow storms). I beat a hasty retreat for the hanger, but about half way
to the hanger
the gusts hit. I brought the plane to a complete stop on dry
ashphalt. The wind
turned me 90 degrees so that I was pointed right into the wind. Now
that's
weathervaning!

Cherokees do not have anywhere near as much elevator authority as I
would have
expected. those engine mount cracks and wrinkles in the fire wall are
most likely from failure to hold the nose gear off when landing.
They are also very easy to either porpoise or wheelbarrow.

You'd probably have to lift it quite a ways too. That would be one
whale of a
wheelbarrow. I'd like to get a picture of one doing that and I have
seen the mains on
several aircraft several inches off while the nose gear was still down.

If the gust is that strong you will be able to steer with the rudder
just fine. Might
get interesting in a cross wind though.
I've had to taxi with the nose gear off all the way to parking at TVC
when there was a
quartering headwind on landing while both the runway and taxiway were
covered with
black ice. Twas easy to do in a 150, but I doubt that I'd be able to do
the same in
the Debonair. Certainly would be interesting to try.

>things are OK, but I still ahve major problems with steep turns.
As for the steep turns, I use the horizon to maintain altitude.
Period...
1) Set up - straight and level, Va, Relax
2) Clearing turn
3) I use my attitude indicator to set the bank to 45 degees (all the
way to 45 and keep it there)
4a) If turning to the left, I pick a spot on the horizon that lies
over the center of the cowling and then try to keep it there as I go
through the turn.
4b) If turning to the right I pick a spot on the horizon that lies
over the left corner of the cowling and then try keep it there as I go
through the turn.
5) I continually scan my instruments - RPM, Airspeed, Altitude,
Verticle Speed, Heading, Turn Coordinator (that is just my technique)
while going through the turn
6) Start my roll out at about 1/2 the bank angle - in this case about
23 degrees.
EXAMPLE: If I am supposed to roll out on a 360 heading, then I start
my rollout at about 337. Don't forget to use that *rudder* on the
rollout.
Ask your CFI to demonstrate it and talk through everything he/she does
during the manuever.
>Also, we started to do some hood work, and that stuff is HARD!!
It will get easier - I remember having trouble keeping the plane going
staight on the takeoff roll... In other words, it just takes practice.
Hope that helps,
Marc
