Patent ID: 8104339

Claim:
A method that determines air data parameters for a vehicle, comprising: receiving a first air pressure from a first port located on a surface of the vehicle; receiving a second air pressure from a second port located on the surface of the vehicle; receiving a third air pressure from a third port located on the surface of the vehicle; receiving a fourth air pressure from a fourth port located on the surface of the vehicle; determining at least one of a total pressure (p t ), a static pressure (p s ), an angle of attack (AOA), and an angle of sideslip (AOS) from the first air pressure, the second air pressure, the third air pressure, and the fourth air pressure; comparing the at least one of the determined p t , the p s , the AOA, and the AOS for each of the identified groupings of four different air pressures; identifying the groupings of four different air pressures that have the same at least one of the determined p t , p s , AOA, and AOS; and determining at least one of an actual p t , an actual p s , an actual AOA, and an actual AOS based upon the at least one determined p t , p s , AOA, and AOS for each of the identified groupings of four different air pressures that have the same at least one of the p t , p s , AOA, and AOS.
