1. A method of providing fault isolation in an air data system which uses artificial intelligence to generate air data parameters, the method comprising:
- receiving an air data pressure value from at least one air data sensor;
generating a fault detection value based upon the received air data pressure value, wherein generating the fault detection value further comprises;
generating a predicted value for the received air data pressure value; and
comparing the received air data pressure value with the predicted value to generate the fault detection value; and
determining if a fault is present by processing the fault detection value through a fault detection network having artificial intelligence.

Abstract
A method and apparatus for detecting a fault in a sensor for an air data system which uses artificial intelligence to generate air data parameters is disclosed. The method and apparatus generate air data parameters as a function of measured values such as static pressures. The system also generates a fault detection value based upon the received value. The fault detection value is then input into a second network having artificial intelligence to determine if a sensor has experienced a fault.
