static port

Is the cabin air the recommended source of static air? Is there a good spot to add a static port on an Odyssey?


Right none of the instruments have a line on the static ports. They jump around a bit, so not sure if that could be a cause.



Thanks

I have cabin air for static air. It's accurate when I have both vents wide
open. Least accurate when both are closed. I can close the vents and watch
the airspeed change. So I can always do a mental correction.

Replaced the steel pitot with a homemade pitot static probe. Pitot worked
fine, static caused inaccurate airspeed reading. Not sure why it didn't
work.

Fastened the pitot static tubes to the inside of the nose with thin layer
of silicone caulk. Then adjusted it down until I got good airspeed readings
at highest angle of attack. Added caulk to affix that angle. I like knowing
I have a good airspeed indication while landing. The silicone allows the
pitot tube to get knocked around but returns it to the set angle.

Hi
If you are looking at the airspeed while landing than the only way you can make s good landing is by accident.
Look 👀 out the front of the plane and establish the angle of attack that will approximately establish 60 mph wen you are a cup ole hundred feet up. Than memorize that angle and don’t change it till you are ready to flare as noteted by your unwavering stare out the front at the far end of the run way. This gives you the clue to flair! Perfectly!
It is what the birds do!!
They don’t have an airspeed indicator.

Happy Flying,

Oh, and I have an external static port on each side of my Gull and also still notice airspeed jiggling. It is what it is and I keep flying enjoying my gullride.

I installed two static ports, one at the fattest point under the door, the
other opposite. That takes yaw out as a variable. Comparing GPS ground
speed with IAS (in still air) gave me confidence in the pitot system. But
Mark has a good point: use the ASI only to calibrate yourself, then use
outside visual clues all the way down. That said, I do like to glance at
the ASI close to the threshold to make sure I don't accidentally carry too
much speed and need to go around.

What kind of static ports did you use? Mind sharing a picture? All P/S instruments jump around, I just would like to minimize it the best I can.



I'm interested in getting better at flying AOA and not airspeed, and I'm improving. Flying bricks in IMC keeps me wanting to "scan", so hard to not always keep an eye on it. I'm trying to take after the STOL idea of carrying as little airspeed as needed.


Thanks

Mine are little aluminum disc things with tiny 4-40 size screws needed and they have a barb facing inside to put the 1/4 tubing on. They were about $15. Mine are in the same place as yours. I didn’t do the altimeter or vsi yet but will soon after I find a cheap gps.

And I got them from Aircraft Spruce.

I used aluminum disc shaped things with a barb on the back side for a 1/4 tube and 4 small holes about 4-40 screw size. They were about $15 if I remember right, and got them from Aircraft Spruce.

I went flying this morning and forgot to take photos of my static ports -
sorry! The attached photo shows the kind of elbow/hose barb I used (widely
available). They screw into a 1" diameter thin disk with a threaded hole
that I epoxied to the skin on the inside. They had a little tit (is that
PC?) sticking just through the wall, so that on the outside, everything was
flush. Had a buddy machine them. The nice thing about this approach is that
the elbow can be installed after the hose is on the barb while allowing it
to rotate to find the most relaxed orientation for the hose (putting less
strain on the epoxy joint), and it can be unscrewed for cleaning.
