From: Rob Kermanj Hi, Anyone using Cleveland's static ports? Is accurate? If so, how did you determine that it is accurate? Thanks. Do not archive.

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. http://www.kilohotel.com/rv8/ http://www.vansairforce.com/community/showthread.php?p=1009217 http://www.kilohotel.com/rv8/rvlinks/GPS_PEC.XLS Tim On 9/3/2015 5:31 PM, Rob Kermanj wrote: > > Hi, > Anyone using Cleveland's static ports?

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.

From: Rob Kermanj 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. Do not archive.
