Static pressure
Air pressure is measured by two sensors: the static port and pitot tube. On some aircraft these are integrated in one probe and others have more than one static port to equalize pressure differences around the fuselage.
Static pressure. Pressure of air that is still, or not moving, measured perpendicular to the surface of the aircraft.
Steep turns. In instrument flight, any turn greater than standard rate; in visual flight, anything greater than a 45° bank.
Static pressure.
A measure of barometric pressure as if the sensor were not moving with respect to the air; Compare: total pressure; Symbols: p sub s; Typical Units: psi,lbf/in-squared; Dimensions: Mass /Time-squared * Length ...
Static Pressure & Shear Stress Distributions
It is clear that, as far as lift is concerned, the shear stress is secondary and contributes mainly to the drag force.
The airspeed is derived from the difference between the ram air pressure from the pitot tube, or stagnation pressure, and the static pressure.
The adjustable barometric scale is necessary because of the effects that atmospheric conditions have on static pressure. At sea level, air exerts 14.7 pounds per square inch. However, as altitude increases, pressure also decreases.

This measures the static pressure inside the helicopter fuselage. The static system is connected to the Altimeter, VSI, and Airspeed indicator.
The system supplies both pitot and static pressure for the airspeed indicator, altimeter and vertical speed indicator. Pitot and static pressure are picked up by the pitot head on the bottom of the left wing.
A navigation sensor based on atmospheric data sensors; usually measures static pressure, dynamic pressure, and outside air temperature; sometimes computes other atmospheric data, such as indicated airspeed, Mach number, calibrated airspeed, ...
Air data computer (ADC). An aircraft computer that receives and processes pitot pressure, static pressure, and temperature to calculate very precise altitude, indicated airspeed, true airspeed, and air temperature.
The static pressure is constant across a slip line although the Mach number changes. Slip lines are drawn in black on the graphic. You can Zoom in for a closer look at the graphic by using the slider bar at the left.
Pressure Head: A combination of pitot and static pressure tubes forming part of airspeed indicator installation.
Primer: A device for spraying fuel into the induction system or combustion chambers of an aero-engine to facilitate starting.
mounted on the outward leading edge of an airplane wing (out of the propeller stream) that measures the impact pressure of the air it meets in flight, working in conjuction with a closed, perforated, coaxial tube that measures the static pressure.
