I am away from my XP10 sim PC, and using the vacation time to start thinking about things to try when I return to "work" :-)

 

One of the subjects that was recently brought in another sim I was using, DCS, was the modeling of control stiffness. This characteristic can affect most non FBW aircraft, like the ww2 models included in that sim.

 

Users were particularly interested in fine tuning of the control forces for instance in a Bf109 K4. The test flight data and pilot reports all mention the controls becoming rather stiff in roll, yaw and pitch above 650 km/h, so, instead of the virtual pilots being able to freely move them at whatever speed they were flying, and particularly when not using force feedback controllers, the authors tried an approach based on a filter that creates a time lag as control inputs are used at higher speeds and G loads.

 

Now, in XP10 we can, in Plane Maker, set a limit for full deflection of the controls above a certain IAS. But I would like to explore the possibility of using a plugin to interfere in the chain of events between the controller inputs and the data actually sent to the flight model calculations cycle. 

 

Do any of you know it this can be done using the datarefs in the sim? I refer to the possibility of creating an artificial lag in the control deflections, without going through X-Plane's own FBW system, or using the menu for reducing control throw with speed, available in PlaneMaker...

A thing to consider, is that at those high speeds, most (I think) WWII aircrafts were subject to severe aeroelastic effects that caused, above a certain speed, flight control reversal. Every aircraft had an "aileron reversal speed", above which the ailerons basically acted like trim surfaces, bending the wing and causing a roll in the opposite side.

 

Some aircrafts, like the Mosquito with a wooden and less rigid fuselage, exhibited also elevator reversal: above a certain speed, the aircraft bended so much that elevator up caused it to pitch down instead.
