1. A method comprising: sensing a first set of parameters; receiving a second set of parameters that does not include any of the first set of parameters; generating a first air data value based on the first set of parameters; processing the second set of parameters through an artificial intelligence network to generate a second air data value; processing the second set of parameters through a plurality of diagnostic artificial intelligence networks to generate a plurality of diagnostic air data values, each of the plurality of diagnostic artificial intelligence networks excluding a different one of the second set of parameters; and identifying, based on the first air data value and the plurality of diagnostic air data values, one of the second set of parameters as a fault source parameter that is associated with a fault condition.
