Autopilot correction times...
On autopilots on current commercial aircraft what is the time delay between the autopilot noting an adjustment is necessary to be made to either a heading/speed/level change and the control surfaces making that adjustment? Also what is the tolerance on speed/altitude/heading (i.e. percentage difference than that required) before the change kicks in immediately.
I mean is it something like:
Change noticed from current setting required.
Wait (how long? is it based on percentage of adjustment needed - further out from required amount the quicker the autopilot makes the adjustment)
Move control surfaces to adjust back to altitude/speed required.
I ask this because in turbulence if the "wait" is too short then it potentially makes for a more uncomfortable ride if the aircraft is forever chasing as close to the speed/level/heading as required. I am no expert so just interested in how the autopilot works out what to do and how quickly.
Hope that makes sense...
