Ron,


I have seen vastly different accuracy on different installations in
different aircraft with the S-TEC 50. On our Tobago, it can be used
well on approaches down to 200 feet.

In my Mooney, I will occasionally allow my STEC50 to fly an approach, if
there is absolutely no turbulence and little change in the winds during
descent. Sometimes it even gets to DH/MDA still on the centerline! But
it's not unusual for it to get 1/2 to 3/4 scale off course.
