Air Data Sensors obtain aircraft angle of attack, sideslip, static pressure, total pressure, outside air temperature, and total air temperature. The primary sensor is a probe which may extend well forward of the aircraft to avoid aerodynamic interference or shock waves.. Many civil aircraft have side mounted orifices rather than probes and for stealth reasons modern military aircraft use flush ports.
Helicopter air data measurement may have a swivelling pitot probe which can measures airspeed down to zero knots (for hover) and work in, sideways, rearwards, forwards and any airspeed combination
These products provide pressure and airflow direction data to data acquisition and air data computers for computation of aircraft orientation, airspeed, altitude, and related information.
