Hi,
Anyone using Cleveland's static ports? Is accurate? If so, how did you determine
that it is accurate?
Thanks.

I have the rounded Cleveland ports. They are pretty accurate. I think
mine read about 2kts low
in cruise. The other ones I had were off by 8kts. You have to fly the
3 or 4-way GPS
course to determine if they're accurate and know the OAT and everything.
Kevin Horton has a good spreadsheet on that. Here are some links. The
3rd link is
the spreadsheet.

I had the old Cleveland ports on the RV-8A - the version that was flush with
the outside skin. Like Tim they were well off in airspeed. I ended up
fixing the problem by drilling a 1/16" hole in the center of a 3/16" round
head rivet, cutting the head off and then using epoxy to glue the head on
the Cleveland static port. This provided enough height to solve the
problem.
On the RV-10 I just used a couple of 3/16" rivets for the static port
(AN470AD6-14 from Van's). I drilled a small hole all the way through the
rivet (get a handful of rivet as it is not easy to keep the hole centered
the whole way through the rivet). The drilled rivets are mounted through
3/16" holes in the fuselage in the standard spots with a touch of pro-seal
(or epoxy of your choice). On the inside of the fuselage skin is a 1"
diameter 1/8" thick piece of aluminum (with the same 3/16" hole in the
center) that is pro-sealed over the rivet shank and to the inside of the
fuselage skin. This provides a rigid mount for the rivet and attached
tubing. A 1/4" nylon tube slides over the rivet shank, with more pro-seal,
to make the connection.
The static ports proved to be very accurate.

Thanks guys for the answers.
I have the Van's method with the rivet head as the static port. At altitude, if
I open the vents, the plane loses a few feet of altitude. My pitot/static connections
are tight and I can only attribute the issue to a leak right at the rivet
head. The RTV method of attaching the tubing to the rivet might be the case.
It looks visually good but I don't dare tug on the connection.
Cleveland's port might be the fix.

very nice information Tim, on that item, where did you put your OAT to
get accurate readings?
