Increasing Sim Rate breaks whole simulation BUG

Hi,

I want to mention another thing that i didnt see any topic anywhere about one of the most essential bugs that feels AP and flying simulation is broken.

When you increase sim-rate and pass x3 or x4 clicks, the plane loses whole AP stability and balance due to wrong trimming calculation. Instead of making calculations on true-time and then multiplying the results according to sim-rate, AP is trying to control trim in real-time with sim-rated fast forwarded move references.

It makes plane impossible to keep its stability and start bouncing in between -5000 +5000 feet. I feel that even damage gets bigger with that fast up and down moves. Sometimes when you fly on speed limits, plane gets damage due to overstress because of that fast-forwaded bouncings.

All this bad simulation makes sim-rate unusable.
Maybe AP is not broken but there are lots of inputs and variables to work it stable.

It has to do with how the pitch changes with wind. The forces just screw up the P&ID’s and with the increased rate the oscillations become too hard to control. They could put in something like in KSP where under time acceleration the craft is on rails but the problem with that is we still need to model the plane, or else you could just shut off the throttle under time accel and the plane would keep flying. Problems like that - It will screw up any failure modes, fuel economy and a bunch of other stuff.

I think you just have to live with the fact you can only go 2-3 times faster.

I dont think its impossible to simulate such an acceleration both in winds and plane control reactions.

The problem is how acceleration is modeled. What is happening is movement is skipping frames while AP is trying to control in a continuous way on real time.

Plane takes only wind input on A point then after B, it results smt like quantum leaps on wind inputs.

It should pass through all wind frames and correct the control, then accelerate the results.

And at last they have finally fixed that issue.

Idk Asobo or FlyByWire mod but with last update we saw that its surely possible to have that sim multiply rate on trim reaction also. Like they do on winds and speeds.

Thanx guyz, whoever did this!
