Did we lose the stall horn somewhere along the way? It seems to be
missing from the default C172.
Regards,
Curt.

As long as we're bitching, I've noticed the slight nosewheel-bouncing
(during the takeoff run) are producing loud squeals again.

BTW, the newly trimmed C172 behaves much better it is almost flyable

Almost? What are the remaining caveats? Besides, that is,
no propeller drag at the higher airpseeds and propeller
overspeeds?

That's why Minnesota elected its current governor, I guess.

The c172 is flyable now but I thing the stall don't reproduce the

My changes shouldn't affect the stall, except for any roll component.

With the JSBsim model, I don't see the decrease of AoA at stall. Instead,
the plane keeps it AoA with the stick completely pulled. It does not
swivel around its CG like a real plane !
I'll try and have a look this

Basically, Frederic's loosing elevator authority before he loses lift.

Ahem, shove it upwards against what force? :)
At zero speed, there is zero aerodynamic force. What holds it down,
if not gravity? At least on the Cherokee

It is a continuous tone, for as long as the angle of attack is too high.
There is no warble or anything else exciting

We've talked about reporting stall as a double rather than a bool --
i.e. there'd be a transition zone where the stall is between 0 and
100%. When JSBSim supports that, we can rig

Apparently you missed my post, I made that change
several weeks ago.
The JSBSim Aircraft::GetStallWarn still returns a bool, and JSBSim.cxx
still treats the stall as a boolean property in some places.
