The Pitot-Static System
One of the primary ways airplanes measure their speed is through the Pitot-Static System. This system consists of a Pitot tube and static ports that help calculate various airspeed indicators.
| Component | Function |
|---|---|
| Pitot Tube | Measures impact pressure to determine airspeed. |
| Static Ports | Measure static pressure to calculate airspeed. |
Airspeed Indicators
The airspeed indicators in airplanes rely on the pressure differential between the Pitot tube and static ports to display the speed at which the aircraft is moving through the air.

Speed Calculation
The calculation of airspeed in airplanes involves understanding dynamic pressure, static pressure, and the relationship between these factors to derive an accurate measurement of the aircraft’s speed.
Air Speed Indicator
The Air Speed Indicator (ASI) is a critical instrument that displays the forward speed of the aircraft, providing real-time information to the pilots for navigation and control purposes.
Ground Speed Measurement
While airspeed indicates the speed of the aircraft through the air, ground speed refers to the speed of the aircraft relative to the ground. Inertial Navigation Systems (INS) are commonly used to determine ground speed accurately.
Frequently Asked Questions
How Do They Measure Plane Speed?
The speed of an airplane is measured using a pitot-static system, which calculates the difference between dynamic pressure and static pressure. The pitot tube measures the dynamic pressure caused by the aircraft’s forward motion, while the static port measures the static pressure of the surrounding air.
This information is used to determine the aircraft’s airspeed.
How Do Planes Track Speed?
Planes measure speed using a pitot-static system, comparing ram air pressure from the pitot tube with static pressure. The airspeed indicator then displays the speed.
How Do Airlines Calculate Speed?
Airlines calculate speed using a pitot tube that measures the pressure difference between ram air and static pressure.
What Determines Airplane Speed?
The airplane speed is determined by the difference between ram air pressure from the pitot tube and static pressure. The pitot tube faces forward, while static pressure is detected at static ports on the aircraft. This difference calculates the airspeed, which is the speed of the aircraft relative to the surrounding air.
Conclusion
Understanding how airplanes measure speed is essential for pilots, engineers, and aviation enthusiasts alike. The Pitot-Static System, airspeed indicators, and ground speed measurements play a vital role in ensuring the safe and efficient operation of aircraft.
Next time you look up at the sky and see a plane soaring overhead, remember the intricate systems and instruments that work together to measure its speed and keep it flying smoothly through the air!
