Ok if someone could explain me that, I will be very happy

I have a simulator, if i pitch up OK, but if I pitch down, my plane sta=

and i don't understand why.


It should be just the opposite: pitching up too far can cause a stall, =
but
pitching down is supposed to *recover* from a stall.

So there are two possibilities. Either the simulator is flawed, or else
you're mistaken to think that the plane is stalling when you pitch down=
.. Can
you tell us exactly what the plane does that leads you to conclude that=
it
is stalling?

Hi,

plane stalls really when i pitch down.
I'm not sure to know exactly how it have been determined but i try to
explain.
A plane stalls in my case if liftcoefficent for a cambered airfoil with
a plan trailing edge flap is equals to zero.
Flaps to calc. liftcoefficient are landing flaps and ailerons.

Go to your local aero club or flying school.
Get into a REAL aeroplane with an instructor and find out what happens
when you pitch the nose down.
And don't use terms that you don't understand....
