Patent ID: 8170730

Claim:
A method of controlling the flight of an aircraft in windshear conditions, the method comprising: measuring flight performance states of the aircraft while the aircraft flies under the control of a control system for operating flight control devices on the aircraft based at least in part on control inputs from a ground station; calculating average gusts encountered by the aircraft with a computer-based system using a reverse system parameter identification function, a reverse spectral density function, and a time counter function; calculating a plurality of covariance aircraft parameter through residual computation with the reverse system parameter identification function; wherein the reverse spectral density function uses the plurality of covariance aircraft parameters to calculate average gust encountered by the aircraft; comparing the average gusts to pre-determined values in a table; and when the average gust exceeds a selected value in the table indicating windshear conditions, and based at least in part on communications with the ground station, automatically activating a recovery system for operating at least one of the flight control devices on the aircraft so as to minimize the effects of the windshear conditions on the flight of the aircraft.
