A friend is restoring a Fairchild 24. It did not have a static

He's wondering where one might install a pair, one per side.
Any experience on this? It isn't real fast so it might not matter.

Does anyone know why the sides of the fuselage, mid-way between the
cabin and the tail surfaces is uses on many aircraft?

When choosing a site for a static port the most important
consideration is turbulence at and near the port. In the aircraft you
have seen that's the smoothest area.

Mounting static ports on opposite sides of the aircraft "averages"
the pressures sensed which greatly reduces errors. Airliners do it, but
I can't see it in home builts. If you have a noticeable error with a
properly installed static port you have bigger problems.
