What are you trying to model?  Real autopilots don't have perfect

fidelity to drive your autopilot.

I found my source for the lag in the turn coordinator:

Here's the most relevant excerpt:

  The dashpot is replaced by a viscous dampener, which causes the turn
  coordinator to react less to turbulence than the traditional turn-and-slip
  instrument.

This makes sense -- without some damping, in turbulence or chop the TC would vibrate back and forth constantly. I'm sure that STEC and other AP makers consider the damping a good thing, not a disadvantage.


All the best,



David
