I installed the Safeair static ports

(see Pics ) 

I've read/heard that the ports themselves need to project slightly 

beyond the skin of the aircraft in order to function properly. These 

project slightly, BUT VERY slightly.

1. Am I going to have a problem w/ accuracy in instruments?

2. Anybody flying with these have any experience?

3. If they are problematic? Is there something that can be done from the 

outside of the a/c to remedy/fix or am I going to have to recruit and 

elf to crawl into the tailcone for me?



It seems I recall John Cox posting some pics of a Cirus installation 

where they actually had afixed a wedge shaped piece of metal just 

forward of the port itself. Could a machined metal disc be affixed to 

the outside of the skin over the existing port?



4. If replacement is in order what has experience led people



THANKS

The issue with the protruding height is not only the port configuration but the thickness of the paint. I smoothed the rivets holding the port in place, and did not locate a rivet in front of the port in-line with the airflow. Next, I stuck a round toothpick in the static port during painting. After painting the hole was carefully smoothed at the opening.

   

  End result was no protrusion nor static source problems.

That looks nearly identical to the Rivethead Aero static ports I installed:

I posted a similar question to the list a month or so ago, and several

people replied off list that the installation should work fine.



You'll be flying long before me so I can't help with the accuracy issue, but

I'll be eager to hear if you have any problems.

I was told that I should put an extra set (making 4) static ports with two dedicated to the TruTrak autopilot. My A&P friend told me to rig each set with the ports on each side of the tail cone and the connection fittings arching over the top of the tail cone. this arch prevents water from accumulating in the fittings.

One pair works fine.  What you really want is ALTERNATE static in

the cockpit, as a pilot-controllable item.  Your friend is

right about the tubing routing, however.  An alternate static can

be installed many ways, but it's just a way of opening the static

line from inside the cockpit.

I have them and do not see an error, but I also do not have paint yet.

Tim did find that if you have them installed and paint both the plane

and the ports at the same time they still protrude, I think the problem

arises when a thick layer of primer/paint is in place causing the port

to not protrude as much. I made sure there was no primer between the

mating surfaces, and all layers of primer and paint will be applied

evenly on the outside.

After paint I will do more testing and follow up with the results.

Does anybody have a source for a valve that will open the static  

system (1/4" Tygothane plastic tubing in our case) to cabin air?

normal position would be "closed" of course, so that the static  

system is only open to the static ports. Alternate position would be  

open to the cabin OR to both the cabin and the static ports.

I'd like to mount one on the far right side of the panel, but can't  

seem to track down a suitable valve.

Any leads will be greatly appreciated.

I used something very much like these:

http://www.valinonline.com/product.asp?prodid 733

You can get them with various fittings, bulkhead mount them,

and they seal well and open with plenty opening to work

well.

My Beech's specified location for it was on the trim panel

by the pilots Left knee, similar to just above where

some Pipers put a fuel valve on the sidewall.  I used that

concept for my -10 and mounted it just forward of the air

vents near the top of that trim panel.  The lever is mounted

pretty close to the sidewall and it would be hard to snag

it open.  I know some people put them in the actual panel,

but there's really no need to be THAT accessible. You

do want it in a place you can easily reach to activate

if your static ports freeze up.

http://www.flightsimaviation.com/data/FARS/part_23-1325.html

You need a heated pitot tube (FAR 23.1323d) and an alternate static 

source (FAR 23.1325 (b)(3)) for IFR flight.  Wonder how many

people building an IFR aircraft are taking this into consideration...

Yeah, the EFIS changes things a bit.  Not gonna do much good if you

smash your EFIS.   Also, for backup instruments, a VSI is not

a commonly installed gauge. Yeah, it's got some useful info, and

as a primary instrument you'd definitely want one, but as a backup

separate instrument it's usually attitude, airspeed, TC, Compass,

and altimeter displayed in any number of ways.



I don't believe though that just because you CAN break the glass

on a VSI that it would be considered as having an appropriate

alternate static source.

John, Safeair  sells an alternate static port. It's a pretty simple 

system. Just a plug that fits into a quick connect fitting also 

available from MSC supply.

While this is an excellent idea and I try to model as much as I can on Type Certificated aircraft which fall under FAR Part 23, our experimental RVs fall under FAR Part 21.  Now if this was mentioned under Part 91 (operations) that would be another story.  Experimental OBAM are bound by FAR Parts 21 and 91.  So while I'm sure we would also adhere to part 43 in maintenance of our OBAM, while 43.1 specifically excludes OBAM, it is probably still a good ides to follow the guidelines in 43.1.

Qualify that a bit more though.  Do you have the OLD Cleveland

ports with the flat face, or the NEW cleveland ports with the

domed face?  The old ones had that amount of error, but I

see more like 2Kts with the new.

I have the new domed set. It helped, from the original flat units, they were about 15 to 20 kts off. So newer is better, but still not very close to accurate. 

 I saw Richard at OSH this year, and ask him about the error, he said the positioning was just a best guess, and you can put them anywhere if it works. He didn't have a problem on his 10, he though his was right on the money. Richard is the kind of guy you can talk to, to bad the people that answer the support line don't share this attribute.

 right about the tubing routing, however.  An alternate static can           

 be installed many ways, but it's just a way of opening the static           

 line from inside the cockpit.

 I was told that I should put an extra set (making 4) static ports             

 with two dedicated to the TruTrak autopilot. My A&P friend told me to             

 rig each set with the ports on each side of the tail cone and the             

 connection fittings arching over the top of the tail cone. this arch             

 prevents water from accumulating in the fittings.
