What is the function of the pitot tube in an aircraft?

Measuring altitude

Measuring airspeed

The function of the pitot tube in an aircraft is to measure airspeed. This is achieved by comparing the pressure of the air entering the tube against a reference pressure from another source, which is typically static pressure. The pitot tube measures the dynamic pressure generated by the air flowing into it as the aircraft moves through the atmosphere. This dynamic pressure is then converted into a speed reading, which is displayed on the airspeed indicator in the cockpit.

Proper understanding of airspeed is crucial for various phases of flight, including takeoff, landing, and maintaining safe flight parameters. The pitot-static system, which includes both the pitot tube and static port, works together to provide accurate airspeed readings and is vital for pilot decision-making and safety.
