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

So clue me, where, pray tell, would a "pitot port" be intsalled on an aircraft?
Name one aircraft that has "pitot ports."

I worked on pitot-static systems for many years.

Do you know what MB-1, TTU-229 and TTU-205 test sets are with out looking them
up?
