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

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

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

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

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 Cheroke

You don't need that; there's enough planes out there where the horn is
really loud, so that after several seconds concentrated listening you are
fairly sure that it is in fact going off ... quietly.

The JSBSim Aircraft::GetStallWarn still returns a bool, and JSBSim.cxx
still treats the stall as a boolean property in some places.

As long as they remember their pilot training and don't hurt
themselves ...

Now there's a good practical joke -- stick the horn tab on with a bit
of duct tape.

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

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

I just committed a new stall horn sample (finally) but I have a question.
Is it supposed to be a continuous tone or is it cyclical? I have the pitch
and timbre matched up(although it plays back at lower pitch inside FGFS) but
for now it lacks the attack envelope of the FS98 sample from simphonics
