AbstractHealth monitoring during flight tests provides a means of data validation in flight. It is possible to design a data acquisition system such that the available instruments incorporate redundancy through analytic relationships. This analytic redundancy may be exploited in order to assess individual sensor system health and to validate accuracy claims. A practical example is presented in which an air data set is compared with GPS in order to isolate failures in the pressure and temperature transducers.
