You need a course in basic aerodynamics. You would learn that pitch angle
and AOA are completely independent. And don't quote Aviation Consumer as an
authority, many of their reviews are full of contradictions.

Read it the Aviation Consumer Guide you ****ing ignorant know-it-all Car
Salesman.

If elevator control is fine, there would be no problem and they would
still
build it like that, wouldn't they. I haven't seen a Saratoga with a
T-tail,
have you?

If I look at an airplane rotating to climb or take off, the tail comes
down
and moves in the axis behind the wings. I never said why. I very well know
that the tail generates downforce to reach equilibrium - but the issue is
the tail moves down relative to the axis to climb. Period. And yes, it
does
it by generating even more downforce than is needed at level flight.

And you don't loose total elevator control, only some authority if you get
near the area, if you want the details. And the area is more than 3
****ing
degrees in bumpy air.

And the plane should pitch down and it does if you approach the stall
slowly. Yes it should (FAA) and does. But if you compensate and hence get
into the area of extreme high attack (of the main wings), the elevator
moves
down even further, into the full airflow BELOW and the plane pitches up
violently. Why? Because you compensate for some loss of elevator control
and
pull real hard. I know you shouldn't do it but people did and didn't like
how it felt, ok?

Your statement about 30 to 40 degrees would lead to a stall is totally
wrong
without connecting it to speed. I pull up a Cessna 152 to 90 degrees
(vertical) if I have the airspeed and if I am crazy enough. (My instructor
did). Before I run out of steam I push and avoid a stall. It's a nice ride
but doesn't last long if you want to live.

It loses elevator control in slow flight with high angles of attack,
not
at
take off.

Obviously, you've never flown one of these things. If your statement
were
true, it would be impossible to stall the plane. Elevator control is
just
fine
in all phases of slow flight, landing configuration stalls, and
accelerated
stalls - exactly as required for FAA certification. Also exactly as any
pilot is trained when checked out on a new type.


Then the tail comes down and gets no air because it is in the
horizontal axis right behind the main wings.

Now, you're really showing your innocence. The stabilator does
*not* hold the back of the airplane up, it holds it *down*. If you
really lost elevator control for the reason described, the airplane
would
pitch down, not up.



That makes the tail less
effective, because the airflow it gets is partly deflected by the high
angle
of attack of the main wing and the airflow does not even reach the
tail
and
is also turbulent. The use of flaps makes this even more pronounced!
A
straight tail in comparison would be way lower in totally undisturbed
airflow and more effective in this kind of flight envelope.

You better go look at one of these things on the ramp. If you were to
get the nose so high, that the T-tail stabilator were totally behind the
main wing, you'd have an angle of attack of about 30 to 40 degrees,
which is about 3 times greater than the stall. The condition you
describe is impossible. You'd be in a spin long before you reached
that angle of attack.



This happens
when you have to ad power to fly slower, it's called getting behind
the
power curve. This does NOT happen when you take off.

I hope you're not an active pilot. Do you really think that getting
behind
the power curve is limited to the tail design of the plane? You can get
behind
the power curve in any airplane, especially any piston airplane. You
need
to get some training on that phase of flight, soon.


Other airplanes don't have the same problem because of their different
geometry. (Longer fuselage and higher or lower t-tail.)
It really has nothing to do with 'well trained pilots'. If you were
well
trained you would know that! Maybe you should find somebody who can
draw
you
a picture. No offense...


Better look at your own picture. With a much longer fuselage, the angle
of
attack required to get the T-tail down behind the main wing, is reduced.
