If I recall correctly it is typically a static port.

If the holes are on the sides, top or bottom of the tube it is static.
If the holes are on that back side of the tube in such a way that in
flight it would create suction at the hole then it is a TE probe.

Our 2-33 has an original dual Schweizer probe on the nose
bowl. One of the probes is pitot but I can not figure out if
the other is the static or a TE probe of sorts. Does anyone
know for sure?

Thanks
