why my plane stalls

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
stalls and i don't understand why.

thank's

Your simulator is broken (or you have not described the situation
accurately).

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?

You're inverted.

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.

Bottle to Throttle..........8 hours.

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....

Please don't call it a plane.
Readers here may take it badly, present company included.

If you're on a simulator, maybe your joystick or yolk is set up
incorrectly? (pitch reversed).

As anyone on this group will tell you in an instant, stalling is not
about pitch *per se*, but angle of attack. That said, one pulls up to
case a stall, and pushes down to get out of one -- unless you're
inverted, or your controls are rigged backwards (which, unfortunately,
has been known to happen).
