What you have described, calculating with tedencies could certainly purposefully be incorporated in the IAS Synthesizer

@falconer1
The concept of an IAS Synthesizer apparently sounds far fetched to you.
I'm quite sure that such a device can be built, although maybe not exactly the way I have described it (The story about the car Homer Simpson designed for one of the Big 3 comes to mind). Some uni could possibly make it work.
About the new weather, flying trough strong turbulence in an airplane today can well be likened with traveling in a speeding bus on a very neglected dirt road, with no suspension and all tires blown.
If the cockpit, cabin and baggage compartment together were made floating in relation to the airframe (as with electronic F1 car suspension technology), the general safety and comfort could be way much better.
