Posted: Mon Mar 13, 2006 6:49 am Post subject: static port location on Series 6?

I am having trouble figuring out where to put my static ports on my series 

6.  I have

combed the manual and cant find any reference to it at all, does anyone know 

where

I can find drawings showing where to put static ports?



I searched the archives and found lots of threads about cabin air being much 

better

than a poorly located static port but no indication where the correct 

location is.



Thanks!

I get my static from behind the panel. It works better than most static 

ports I have seen. I think John McBean has a kit. Having a correct 

static port is as important as where it is put. It is easy to get an 

error of over 10 mph at approach speeds with an incorrect static system, 

which can really cause problems on the first flights. I suggest that if 

you have a static system you disconnect it for the first few test 

flights as the error will only be 1 or 2 mph at most and will not mess 

up your first approaches and landings before you have a feel for the plane.

I have two friends with Kitfoxes, one has a V the other has a II, both put  

theirs on the sides of the fuselage just about where the pilot and pax fingers  

would be when theuy let them hang out of the open doors. The way you tell 

they  are correctly placed is by observing no change in from runway altitude as 

you do  your takeoff roll and just as you lift off. There should be no  change.

Not that I disagree, but if it's within 1-2mph, you won't get much better

than that no matter where you put it.



In reference to your question, I thought I read here that Skystar put theirs

somewhere aft, near the leading edge of the stab, and about 3" up from

bottom of the fuse. Correct?



The good thing is, when you do your stall/minimum speed testing, you'll know

where your 'fox's stall is at. Multiply that by 1.3, and that's your Vref,

or speed over the threshold. It's not your approach speed, or touchdown

speed, although it can be both.



If you've got a really messed up installation, let's say your plane will

stall at 80mph indicated. Multiply by 1.3, and you should cross the runway

threshold at 104 indicated. It really doesn't matter what the actual speed

is. It might count for bragging rights.



Some people are very meticulous, and an accurate a/s indicator is important.

But given the tools most homebuilders have to work with, anything within

5mph either way would be totally acceptable to most folks. Just adjust Vref

accordingly. I think 1-2 mph error correction is way out of reach without

sophisticated, expensive, and calibrated equipment. Maybe your FBO has a

tester? But be forewarned: most FBO's are run by cheap bastards who don't

calibrate their equipment, or even take care of them, regardless of what the

FAA does or says.



My 2, for example, is static ported in the cabin, and stalls around 40

indicated. My approach is 55mph, Vref is 50mph, and touchdown is whatever

touchdown happens to be. I don't know, nor do I care what speed the

indicator says I'm actually flying at. I have a GPS for ground-speed, and

top-speed isn't of major concern to me.

Someone else was asking me about Static port location... Hopefully they are

on the list...



Anyway, The following is the tested location on the 1-4 & 5-7



Model 1 - 4:	27 inches forward of the leading edge of the horizontal stab

and 5 inches from the lower longeron



Model 5 - 7:	24 inches forward of the leading edge of the horizontal stab

and 2.5 inches from the lower longeron



Fly Safe !!

Scooby,



Go to our "own" Skystar site found here:



(Folks, take notice of this address.)



http://www.sportflight.com/skystar/



Click technical support, next - click Instruction/Documents, in the right 

upper corner you'll find the document: Static Port Install.



This is the one you are looking for as a pdf file.



Good Luck.



Torgeir.

I agree, that is why I leave my static behind the panel. You can get a 

little more error at cruse speeds, but not a lot. I have seen the static 

port cause enough of a speed error that it really messed up the first 

few flights as the pilot was using ball park numbers for the approach 

and landing before he could do stall testing. You also need to leak 

check your pitot system. A small leak, a lot of times in the wing fold 

area, will cause a big error also. The best way to check it is to tape a 

child's balloon to an inch or so of tygon tubing, blow up the balloon 

and slide the tube on the pitot tube and slowly release the pressure. It 

will give you somewhere around 100 mph indicated but that is not 

important, what is important is that the balloon stay inflated. It 

should stay up for a few minutes at least. When you remove the balloon 

let the pressure off slowly.  If it goes down you have a leak. A hole so 

small you can not see it can change your airspeed 15 mph or more. You 

may be able to use 1.3 vso on the early models, but except for short 

field work 1.3 does not give you enough energy to flair power off in a 5 

or 6. (The 7 does a little better slow).. This is a light weight plane 

that decelerates fast and you can really drop it in. We have been 

talking first flights, so I would keep it a little faster until you find 

out just what speeds work for you and your plane.

An interesting note on leaks. When I got the plane, there were at least 5

connections (rubber to tygon, tygon to rubber, etc.) and consequently, it

leaked. It was easiest to just gut it, so I scored some plastic water line

and neat little connectors at the Home Depot Aviation Store, and put a new

line in.



Well, one day, I'm working on the plane at the airport, and a guy stops by

to chat and look. He poked his head in the cockpit, and say "Hmm, your

airspeed indicator is broken. It's stuck at 35." Well, I finished my

pre-flight, and in the process, removed the pitot cover. When I climbed in,

the a/s was at zero. Curious, I put the cover back on, and it promptly rose

to 35, and stayed there. Now when I go out to fly, I check the a/s and see

what it's reading. One time it was 60mph. As the air heats up, it expands,

and the airspeed rises. Now that's a tight system.



I actually put a small hole in the pitot cover, as I am afraid that if the

temperature drops, and creates suction in the tube, I suppose it could break

the indicator. I did the same for the fuel tank tubes, as I don't want

pressure on the tanks and lines when it's hot out.



As for 1.3 Vso, I'm just going by a rule-of-thumb, for lack of any other

info. It seems to work, but I'm getting to where I like a steeper, slower

approach, so I don't float too far past my touchdown point. For the first

flights, I just used a speed that felt "normal" in the controls. You can

tell by how the ailerons and elevator "feel". Mine sure loses the elevator

when really slow.

I have my static source behind the instrument panel, and it seems to work well until I open the doors!  There is also some error when doing a strong slip to  lose altitude.  More importantly, the static errors will effect your altimeter, and our encoder if you are using Mode C.  There may be a conflict between your indicated altitude, and that which is reported to ATC.  I'm not sure how much "off-altitude" you are permitted until the ATC/FAA becomes interested.

ATC gets interested if the altitude that you report differs from 

your mode-c by more than 300'.  That was true the last time that 

I sat at a radar scope - about 4 hours ago.

Of course, if your encoder is vented to cabin static air, the 

report that ATC derives will show the same thing that your 

altimeter shows.  That may or may not be your actual altitude 

above sea level.  That is an important consideration if you are 

counting on ATC to keep you out of the rocks or to provide 

vertical separation with other aircraft.  So don't think that you 

can bluff your way out of Class A or B airspace by resetting your 

altimeter.

I say that "ATC derives" because encoders are basically stupid. 

They send your pressure altitude to the ATC computers.  I have to 

set the ATC computer to the local altimeter setting just like you 

would do in your Kollsman window.  The ATC computer then corrects 

the pressure altitude from your mode-c and displays it to the 

controller as an MSL altitude (when below 18,000 in the USA). 

Above 18,000 feet everybody flies at a pressure altitude (Flight 

Level) by setting the altimeter to 29.92.  If the local pressure 

is below 29.92, some of the lowest flight levels become unusable 

for separation.  They will not be a true 1,000' (or more) above 

17,000.  I'll leave that brain teaser for you to figure out.  A 

little note here - the ATC computer is actually set by an array 

of digital altimeter setting indicators.  The local pressure 

setting is updated automatically once each minute.  In a large 

geographic area, the computer will apply the proper correction to 

your mode-c based upon the adapted altimeter region that you are 

flying.  If the automatic altimeter interface fails, I can set 

the altimeter manually.  I am required to keep the ATC computer 

within .02 inches of actual local pressure.

Now there's more than you wanted to know.....

Interesting, and good points to consider.



Before flight, I set my altimeter to field elevation, and the Kollsman baro

setting is way off (.10 or more). But my altimeter reads very close to what

my GPS says I'm at in flight. Interestingly enough, when I fly for the Air

Force, our GPS reading is significantly off from indicated (by a couple

thousand feet). Now that you mention it, I think it is due to setting 29.92

at 18K'. Hence the GPS would be actual, and the altimeter would be relative.



The only bad point to venting to the cabin (and some mentioned this before),

is that the altimeter jumps around a little. Not much, but I wonder if

that's bad for the mechanism over the long run.



Bradley
