Jim,

Typical autopilot systems just do a 25° bank angle and let
the rate work itself out.


Uhm, with the proliferation of rate-based AP systems (both from S-TEC
and King), that statement simply doesn't hold true anymore for GA
aircraft. It may have been true way back (can't imagine it, really,
though, 25 degrees seems very steep), but it certainly isn't any
longer. The S-Tecs (at least the 50) do 90 percent of standard rate,
the King KAP 140 is similar.
