Keywords: air data, neural networks, failure management

Two fault tolerant procedures have been developed in order to estimate the flight parameters (pressure altitude, Mach number, aerodynamic angles) from local measurements (pressures and flow angles) provided by air data sensors. The first one uses polynomial functions while the second procedure is based on the neural networks.
