Curious if people connect both the static and dynamic ports in a plane config.
I have read connecting the dynimc port alone is needed, the static port in the feusalage is sufficient and does not need a tube connected to the sensors static port.
Thoughts
In my opinion, it depends on the fuselage, whether there are any major deviations from the outside air pressure. For example, if there are only narrow vents and their airflow hits the sensor, it is certainly bad. Or if pressure equalization is too slow in the event of rapid climbing or descending.

Hi Rolf, if i understand you are saying there needs to be a lot of airflow through the fuselage and little disparity between external and internal pressure for this situation to work in your opinion correct?
I was looking at how Ben from 3dxr sets up the air speed sensor, that model looks like virtually little to no airflow gets inside the feusalage from what I can.
The feusalage i’m working with on my project is a Ranger with a few small vents near the nose and that is it.
I’ve read extending the tube is better than extending the wiring to the flight controller. Believe the limit should be less than 1M for the cables before signal integrity issues. The longer the tubes the potential for more delays is a concern as long as there is no kinks or leaks.
Thoughts
The important thing is that the outside static air pressure prevails inside the fuselage. This may or may not be the case.
The cable length is not a problem if a sensor with CAN bus is used.
Rolf
Tracking, the cable length was in relation to digital air speed non CAN bus variant.
If you can use an external static port on the probe.
Will do, I ordered more tubing already.
