Pitot pressure vs Static pressure | Difference between Pitot pressure and Static pressure
This page compares Pitot pressure vs Static pressure and mentions difference between Pitot pressure and Static pressure.
What is Pitot static system?
• It is pressure sensitive type of instruments used in aviation industry for measurement of aircraft's parameters such as airspeed, altitude and its trend, mach number etc.
• Pitot static system consists of components which include pitot tube, static port and pitot static instruments.
• This system is very critical part in an aircraft for safety perspective.
• It is the pressure usually obtained from pitot tube which is located either on wing or in front section of
• It is measure of ram air pressure. This pressure is equivalent to stagnation pressure in ideal conditions.
• The ram air pressure is directly proportional to the airspeed. Hence airspeed increase results into increase in ram air pressure. This is measured by airspeed indicator after appropriate translation.
• It is tapped using static port of pitot static system. Static port refers to
flush mounted hole on fuselage of the aircraft.
• Static port is placed in undisturbed area where air flow can be easily accessed.
• Static port can be one or multiple as per requirements in an aircraft. In multiple static ports, average pressure is used for more accurate and optimum results.
• Static pressure decreases when aircraft climbs up.
