I'm not sure if you're aware of it, but most autopilot manufacturers publish
the POH's for their autopilots on their websites in .pdf format.

Is there any one here flying a 172 using an autopilot?

I think on longer flights (3+ hours) and autopilot would be an advantage,
however there are some in the old school that think it is not necessary.

I'd like some opinions.

I just tried using the AP on the C172SP I rent from the local FBO last
time I flew, about two weeks ago. I'd never actually used it during
training or in the two years since I got my pilots license, and I
always wanted to try it.

So two weeks ago I did the preflight checkout of the unit, and then
took off and climbed to 3000 feet. I punched in the "AP" button, the
"ALT" button and selected "Heading" as a choice. Then I sat back and
watched while it turned the few degrees needed to lock to the
Directional Gyro's heading and held it there while sticking precisely
to 3,000 feet. The morning was hot and moist and very very still so
the AP had little work to do once it got where it was set.

I tried moving the compass bug a bit to one side or the other and the
AP dutifully tracked to the new heading as it should. I did not try
using it to track the GPS or the VOR, although it could.

I can see this as being a really important tool when flying solo and
having to change frequencies or look one up or any of a number of
occasions when having the Auto Pilot on would be of valuable
assistance.

I'm seriously considering purchasing a non certified unit for my
homebuilt.
