Recently while I was on a flight, I've noticed this area near the front door on a Boeing 767 aircraft. I'm a total aviation noob, I just wonder what are these and what they are used for.

One of the standard instruments of an aircraft is a "Pitot tube". This instrument allows measurement of the forward air pressure as the aircraft moves through the air. By this measurement the instrument can estimate the relative air speed of the aircraft.



In order to make the measurement, the forward air pressure is compared to the side air pressure and the difference between the two is presumed to be due to the force of the aircraft moving through the air. Thus, the measurement is a relative one, comparing the forward air pressure to the air pressure on the side of the plane.



The "static ports" allow air into the instrument to provide the input for the air pressure on the side of the aircraft. They are called "static" ports because in general they take in air at the ambient pressure which does not change very much as compared to the pitot tube which takes in air as the plane rushes through it, thus frequently changing according to the speed of the plane. The pitot tube is usually located on the bottom of the plane and is pointed forwards.

  • In fact, the pressure at the static ports will drop as the aircraft's speed increases (Bernoulli principle); you're correct however, that the difference between the "ram air" pressure at the pitot port and the velocity-reduced pressure at the static port gives IAS.
