Pitot tube pressure

[Av8torTom]

Does anyone have an idea of what pressures the pitot tube is seeing in your typical GA aircraft. Obviously it's a function of speed, but are we talking a couple PSI? fractions of a PSI?

Thanks,

T.

Pick your flight conditions and read the dynamic pressure down below using the link above.

Have some fun with it.

Somewhere around 1 psi at about 240 mph. It?s a square function, so it?s only 1/4 psi at 120.
