That does seem strange -- you shouldn't hear it even if you have got yourself into an accelerated stall somehow, because stall horns don't tend to actually know about loss of laminar flow.

[Flightgear-devel] Stall warning
I just tried this on a freshly updated CVS build: Take off in the 172 (I used the c172r-3d) and climb to say, 2500'. Trim the aircraft and with the wings level, pull the power back to idle. Hold the nose up to allow the speed to decay and enter the stall. The stall warner goes off as expected at about the right speed, IMO. Now drop the nose a little and let the air speed build to above Vs still with idle power. I repeatably get the stall warner to well over 70kt indicated. Are other people seeing this? Is it normal? (I've never just dunked the nose on a 150 or 152, but I'm sure the stall warning would go as soon as the flow re-attached to the wing... I tried looking in the property tree to see what the fdm was using but I didn't manage to sustain the attitude and airspeed without a joystick I'm afraid.
