    This report describes the investigations- carried out to13; calibrate the 5-hole probe for flow angles from ATTAS flight data. An algorithm based on DGPS for the real-time calibration of air data systems using Kalman filtering in MATLAB has been developed.Wind box maneuvers were executed at 8000 and 16000 ft. to obtain sufficient variation in a,(3 and TAS of the aircraft.The estimates of the air data calibration coefficients using DGPS based Kalman filtering closely match with the ones obtained by using OEM to dynamic maneuvers
