Right, you don't have a clue how a transport is instrumented for air
data,
Dan.

A pitot tube provids both static and pitot ports, but the pitot tube is
unreliable, so 40 years ago most transports switched to static ports and
pitot ports.

So Dan, what did you do in the Air force? I hope it was some job where
you
might have at least some knowledge of avionics; otherwise, you mostly
speak
out of turn.

No such thing as a pitot port, never has been.

Poor Dan, off into denial.

A pitot tube only provides pitot
pressure. A pitot-static tube provides both.

My goodness, Dan, you really are clueless.

Say again what you did in the air force, Dan.
