Each integrated system is carefully fabricated to exacting specifications to ensure reliable, accurate attack angle measurements. The controller pod puts out analog voltages ranging from 1 to 6 volts, which the software (a LabVIEW VI running on your data acquisition host computer) interprets as attack angle and airspeed. To obtain corrected airspeed, you must provide measurements of local barometric pressure and temperature. Otherwise, the software assumes a standard atmosphere at sea level.
