Robert is being rediculess to claim that a pitot tube produces some total
pressure and then the static port pressure is subtracted twice to make IAS.
The whole point of using a static port is to be able to take the guts out of
a pitot tube and produce only pitot pressure, thus increasing the
reliability of the system.

Perhaps this will help:

Hang on here a second now Jim, you still need two samples. As Dan
says you need 'static pressure' to read the altitude from and you
need 'pitot pressure' (ram air pressure) as well as the static
pressure to derive the airspeed reading from. Sounds like you're
saying that you can read 'both' from just the 'ram air pressure'
alone. Or did I misunderstand you?

Jim has finally figued out what a pitot tube is, but somehow he still wants
to be correct in his archive troll. It is a great paradox.
