A pilot familiar with that plane is almost certainly going to find it
very unstable in the pitch axis, and complain that the nose bounces up

Is the null zone there in a real aircraft (backlash), or just a
feature of the sim to allow the pilot to go and grab a cup of coffee?
I think it's a different attempt to compensate for the lack of control
loading.
-1.0 = -1.00
-0.5 = -0.25
0.0 = 0.00
This is a good response, but it also implies that at 0 deflection, the
control is totally nonresponsive (gradient is zero). Shouldn't we
simply add a linear term here? That would make the control linear
around the centre and transition into a square response at higher
deflections.
Major A writes:
Yes, but wouldn't it be better to have at least a small amount of
control around the centre?
You do. Unlike a dead zone, this approach has no location where
moving the joystick will not produce some kind of input.
All the best,
David

Just an idea -- if someone were to build proper force-feedback
yoke/pedals/etc., would FlightGear be able to drive them
realistically? I.e., is force on the controls part of the FDM?
You could build a software interface to your hardware that could read
the appropriate control
Ron,
I must admid it, you have made my day.

Very few MSFS AC have 'realistic' flight models. ;) Though AVSIM
reviewers and a bunch of desktop pilots often think they are.
FS2K+ can't use realistic values of Cm_q and Cn_r at Mach 0.7/30,000

I haven't looked into it for lack of time, but a bunch of MSFS
enthusiasts made landscapes for the Netherlands that might be converted
into FlightGear format, and I hope that such positive sharing will
really take off.
