Pitot Static System: How it Works and Why its Important?

Share This Post

The pitot-static system is a vital part of any aircraft. The role of the system is to measure pressure and temperature at different points in an aircraft. It helps to maintain stability and provides accurate readings so that pilots can land safely.

Pitot Static System

The pitot-static system is an important part of any aircraft. It is used to measure airspeed and altitude, both of which are critical for safe flight. The pitot-static system consists of:

  • Pitot Tube – This measures the dynamic pressure of the airstream against the surface of a tube that’s pointed in an upward direction (like a straw).
  • Static Ports – These measure static pressure inside the aircraft cabin or fuselage; they’re usually located on either side of an airframe’s fuselage near its nose, although some military aircraft use one large port instead.

How the Pitot Static System Works?

The Pitot-static system uses pressure differences to measure airspeed. The pitot tube measures dynamic pressure and the static port measures static pressure. The difference between these two pressures is used to calculate aircraft speed and altitude.

The principle behind this system is that a fluid which has been accelerated will exert a force on its surroundings, while a stationary fluid will not (Newton’s third law). As air flows past an object it is pushed away by the forward motion of that object; this creates low pressure areas behind them which draw more air into those regions than would otherwise be present if there were no movement at all.(1)

Purpose of the system?

The Pitot Static System is used to measure the airspeed of an aircraft. The system consists of two components – an airspeed indicator and static ports. The pitot tube measures dynamic pressure (the pressure exerted by moving air), while static ports measure total pressure (the combined effect of static and dynamic pressures).

The purpose of the pitot static system is to provide accurate information about your aircraft’s velocity in relation to the atmosphere around it. This data is then used by several different instruments on board your plane, including:

  • Airspeed Indicator – Measures dynamic pressure through a small hole in front of the faceplate with an internal expansion bulb that expands with increased speed or altitude, thus increasing its diameter and registering higher speeds;
  • Attitude Director Indicator – Uses information from gyroscopes within itself as well as other instruments like VSI/Tachometers/Turn Coordinator/Heading Indicators/Turn & Slip Gauges etc…to show flight director information such as pitch attitude, bank angle & turn rate indications;

Proper Installation of Pitot Static System

Pitot-Static systems are installed in the nose of an aircraft, and they measure airspeed and altitude. They are very important for safety because they provide information to pilots about how fast their plane is going, which helps them make decisions about taking off or landing. This information can also be used by pilots when deciding whether or not there is enough wind for them to take off safely.

Pitot Tubes: These tubes are installed on top of your airplane so that they face forward towards the front of your plane (i.e., towards where it’s going). Static Ports: These ports are located at either side of each wing tip as well as underneath each wing tip near where it meets its fuselage

The pitot-static system is an important part for any aircraft.

The pitot-static system is an important part for any aircraft. The system helps to measure the speed of the aircraft by measuring pressure differences created by moving air and static pressure (the pressure at rest).

The static port measures static pressure, while pitot tubes measure total dynamic head (pressure + velocity head). When combined with airspeed indicator calibration tables, these readings help determine true airspeed or TAS.

Pitot tubes are located on both sides of an airplane’s fuselage immediately in front and behind each wingtip; they can also be found on top or bottom sides near leading edges of wings or horizontal stabilizers (tail fins). This allows them to collect accurate readings regardless of whether your plane is flying straight ahead into wind or coasting downwind with no wind pushing against it.
