Naval Aircrewman – Mechanical (AWF) Test 6 Practice Test

A Pitot tube measures dynamic pressure by utilizing ram air, which is the air pressure generated by the aircraft's forward motion. When an aircraft moves through the atmosphere, the ram air enters the Pitot tube, creating a pressure difference that can be converted into airspeed readings. This dynamic pressure is essential for determining the aircraft's speed relative to the surrounding air. Static air, on the other hand, is measured by static ports and is used in conjunction with ram air in determining altitude and vertical speed, but it does not directly influence the airspeed measurements taken by the Pitot tube. The distinct function of the Pitot tube focused solely on capturing ram air highlights its specialization in providing vital flight information, such as indicated airspeed.
