my plane is suffering from almost instantaneous acceleration but I've managed to slow it down by using an airbrake that activates when accelerating too fast, but as a side effect the said airbrake limits me from passing 600Mph, I also have a separate airbrake for high AOA braking which slows the plane when pulling the stick.

currently this is the code to the acceleration airbrake: (GeminiAI helped me)

smooth(clamp01(rate(TAS) / 13), 0.5)

I was hoping someone with better understanding on funky trees can help me with this dilemma :)
