A question for those who have gone before me. I am just getting to the stage of planning my static system. I plan on putting in two static ports, one on either side of the fuselage, as suggested in the  manual. The recommended position is about half way along the sides of the baggage area. They suggest  using a Nylon Nylo-seal 268N fitting bonded into the honeycomb of the side panel. This would protrude what looks to be about an inch into the baggage area. The Nylo-seal tubing then attaches to the fitting, which will result in the whole connection protruding at least 2” into the baggage area.

 

Whilst I am sure this will work well as far as the static system is concerned, it seems to me that it will only be a matter of time before an errant piece of baggage being placed into the baggage area will land on the protruding tubing and damage and/or break the nylo-seal fitting.

 

What have others done about this? I thought of using a Nylo-seal 269N elbow fitting, but it is not clear (at least to me!) from the specifications that this will work.

 

I am interested in what others have done.

 

Thanks for help.

In the 360 that I purchased, I believe the
builder put some kind of protective box (wood by the feel of it) around the
sensitive areas. I’m not certain, but it appears he also ran some other lines or
wires through the area because the boxed areas seem bigger than necessary for
just the static system.
 
Hope that helps,
Dave

Here´s what I did:
 
I bought a couple of expensive 90 deg. static port
inserts and ground them down, so they were actually just a 90 deg. metal
channel, ending in a hose fitting. I could have saved a lot of time and $ if I
had just bought two AN842 elbows, but I was not that clever back
then.
 
 
 
Here you see the positions marked on the inside of
the fuselage. I removed the core material around the positions and, probably,
covered with 2 BID.
 
Then I drilled a 1 mm. or so hole, inserted a loose
oiled drill bit from the outside, hung the ground down static port (AN842
elbow) on the drill bit, secured it with a dab of instant glue and
finally
locked it in place with flox and, maybe, one BID,
leaving the hose fitting free, of course.
 
 
 
I had carefully planned my fish bone interior to
match the static ports, so that they, and the static line, would be covered by
one of the "bones".
The matrix for the "bones" is fabricated on the
fuselage and is made of 2 or 3 BID on release tape. The "bone" that houses the
static line is covered with 1/4"
white foam on the front, nicely rounded and covered
with 1 BID. The rest of the "bones" are covered with 1/4" soft foam padding and
everything is wrapped in
blue alcantara. I then carved a channel for the
static line from the backside. The static line runs down into the cable channel
below (see first photo), that consists of
the coreless area with a 2 BID cover over
it.
 
 
This is what it looks like when finished. First a
layer of 1/4" soft foam is glued to the fuselage. Grey alcantara glued on top of
that.
Channels carefully cut where the blue matrix is to
be fixed to the fuselage. Velcro part 1, maybe 5/8" strips, glued to fuselage in
those channels,
velcro part 2 glued to blue matrix.
 
 
Same procedure for the headliner. You can see the
static line on the LH fuselage side (RH side of the photo if viewed from
Australia).
 
I did the side panels for the seating area slightly
different, mainly because of the rudder cables and stub wing
opening.
 
 
 
I first fabricated a flat 2 BID panel on the table.
I then cut it to shape and double curved it, which was a bit of a pain. I had to
make several cuts
from the outside towards the middle of the panel,
fix it to the fuselage with hot glue and cover the cuts with 2 bid, in order
to produce a shape that
fit the fuselage nicely. I then covered the panels
with soft foam and grey alcantara and then velcro-installed the blue "bone"
matrix, that I had pre-made directly on the panels.
This way I have two loose panels (yes, installed
with velcro) that also close the stub wing opening.
The foot wells and nose gear well are just covered
with some helicopter padding that is cut to shape and folded over and sewn at
the edges.
 
IMPORTANT:
"Bone" matrixes and window frames must be
fabricated on release tape in the exact spot they will be installed!!! It
is NOT possible to just make
a flat piece of 2 BID, cut it to shape and install
it with velcro. All surfaces are double curved.
 
 
All in all, I think it is a nice result. It is
rather time consuming, though, but it is good fun, lightweight and inexpensive.
No sewing required, this is a job you can do, and do nicely,
without involving professionals.

Rob,
I bonded a 90 degree AN fitting into the fuselage skin.  The attached hard line then sits flush against the inside of the fuselage. 
Also, I found that two ports were not needed so flew for the first 12 years on one.  I added a second port for the autopilot.  Mechanical VSIs generate some flow in the static line which the auto pilot will interpret as a small pressure difference until the VSI reaches equilibrium.

Rob,

 

Two of these static ports came with my Legacy kit.

 

http://shop.lancair.com/inventoryD.asp?item_no=4937&CatId={BA344909-613F-4C45-A718-0DB8D27FF50F}

 

They require a quarter inch hole in the
fuselage and they are just proud of flush with the exterior and maybe a half inch into the interior of the baggage area.  I floxed them in. 
I thought that I might have to do something to the exterior to affect the accuracy, but a four direction speed test shows that my airspeed is within
one knot of the gps.

On the 235, the static ports are located behind the baggage
bulkhead and a couple inches below the longeron. I just bonded in
the nylon fitting recommended in the plans. The nylon tubing slopes
upward from the ports to the tee in the center so as to drain out
any water that might get in the ports. I haven't flown yet so I
don't know how my static system will perform. I do know that
Clarence Grubbs, whose static port location was identical to mine,
had to bond little a vertical wire in front of each port to get his
cruise speed calibrated.



Port is in the lower right of this photo:

On my Legacy I floxed in the same part that Bill did.  It's very low profile, and the Legacy has a recessed channel along the left and right sides of the baggage bay for cables and static lines.  In my case, I made the port perfectly flush with the external fuselage skin.  I haven't rigorously tested the IAS or TAS.  In spite of the hump in the tube, it still gets water occasionally.  
My cabin interior has removable upholstery sections that cover the wire tunnels.  They pretty much make everything disappear.

Tim,

 

That’s a very impressive upholstery job! I’m not sure I have the time for something so ambitious though. And I like the way you have used the features on the sidelining to hide things.

 

Thanks for taking the time to put it up for everyone to see.

 

As for the plumbing to the static ports, did you use clear plastic tubing or nylo-seal tubing?

Rob Stevens.

I like the idea of the 90Deg AN fitting, and that it keeps the line flush with the side of the fuselage. Did you run hard line ( I presume you mean ¼” 5052 Al line) all the way to the panel, of did you change to nylo-seal at some point? If so, how did you join them together?

 

Thanks for your comment reference the static ports. I am intending to operate my aircraft IFR, and will therefore need a pair of “balanced static ports” according to my research of our Australian rules. Not sure if that applies in the USA.

 

Rob.

Rob,

I bonded a 90 degree AN fitting into the fuselage skin.  The attached hard line then sits flush against the inside of the fuselage. 

Also, I found that two ports were not needed so flew for the first 12 years on one.  I added a second port for the autopilot.  Mechanical VSIs generate some flow in the static line which the auto pilot will interpret as a small pressure difference until the VSI reaches equilibrium.

A question for those who have gone before me. I am just getting to the stage of planning my static system. I plan on putting in two static ports, one on either side of the fuselage, as suggested in the  manual. The recommended position is about half way along the sides of the baggage area. They suggest  using a Nylon Nylo-seal 268N fitting bonded into the honeycomb of the side panel. This would protrude what looks to be about an inch into the baggage area. The Nylo-seal tubing then attaches to the fitting, which will result in the whole connection protruding at least 2” into the baggage area.

 

Whilst I am sure this will work well as far as the static system is concerned, it seems to me that it will only be a matter of time before an errant piece of baggage being placed into the baggage area will land on the protruding tubing and damage and/or break the nylo-seal fitting.

 

What have others done about this? I thought of using a Nylo-seal 269N elbow fitting, but it is not clear (at least to me!) from the specifications that this will work.

 

I am interested in what others have done.

 

Thanks for help.

Thanks Bill. Another good solution. I wasn’t aware of these.

Rob,

 

Two of these static ports came with my Legacy kit.

They require a quarter inch hole in the fuselage and they are just proud of flush with the exterior and maybe a half inch into the interior of the baggage area.  I floxed them in.  I thought that I might have to do something to the exterior to affect the accuracy, but a four direction speed test shows that my airspeed is within one knot of the gps.

Thanks John. Yes, if it was behind the baggage bulkhead I wouldn’t have a problem. With the Nylo-seal fitting recommended in the manual.

 

By the way, the nico-press sleeves arrive OK. Thanks.

 

Rob.

On the 235, the static ports are located behind the baggage bulkhead and a couple inches below the longeron. I just bonded in the nylon fitting recommended in the plans. The nylon tubing slopes upward from the ports to the tee in the center so as to drain out any water that might get in the ports. I haven't flown yet so I don't know how my static system will perform. I do know that Clarence Grubbs, whose static port location was identical to mine, had to bond little a vertical wire in front of each port to get his cruise speed calibrated.

Port is in the lower right of this photo:

Rob,


the nylo-seal elbow fitting works fine.
Make sure you route the tubing as seen on my picture, so no water will enter the lines!
To protect the fitting, put some micro around and cover with 1 bid of glass.

This is a common misconception. Airspeed tests do not show that the static port is
free of error. It only shows that the static port and pitot port have the same pressure errors at the tested airspeed.

To test static port accuracy, you need to fly different airspeeds at the same known altitude and check for any variation.
I used the horizontal roofline of the tower at my local airport as the altitude reference and flew successive laps of the landing pattern at speeds ranging from 60 kias to 200 kias. The faster I flew, the higher the indicated altitude (+300' at 200 kias initially). The errors were parabolic (depending on the square of the speed) as expected. Based on that
information, I was able to reposition the static port until the altitude error was reduced to about 30 feet over the usual speed range. 

I am using a Piper style combined pitot-static blade on the bottom of the wing. The adjustment that I made was to remachine the end of the blade to a different angle to make it more forward-facing.

After the static port is calibrated, THEN check the
pitot pressure by comparison of ASI with GPS speed.
