Software compensation for Air Data Computer sensors

Sensors for the Air Data Computer must be precise in wide operating environment conditions. Besides choosing the best sensor for these purposes further accuracy improvement is necessary. Calibration method, in which temperature effects and non-linearity are taken into consideration, is presented in the paper. Static pressure probe error is another problem. For Air Data Computers, assigned for the small aircraft with augmented control system, software compensation of the static pressure error is implemented using access from another devices information and angle of attack computation. The soft angle of attack simulation tests show the method property.
