Avionics are a critical piece of the management of any aircraft, spacecraft, or launch vehicle. Avionics provide the central nervous system of the vehicle, hosting both management and control algorithms. As such, avionics failures can have significant impacts on vehicle operations and mission success. There are two basic types of architectures employed in avionics systems: federated systems and modular integrated systems. These architectures can determine the avionics system response to managing failures within the avionics system. Avionics operate in a variety of environments from tropical launch sites to the vacuum of space. These environments play a significant role in the failure sources and resulting mitigations. Design faults, manufacturing faults, and environmentally induced faults are the major sources of avionics system failures. This chapter explores the various failure management techniques currently employed, dealing with the detection of, response to, and mitigation of both low‐level and high‐level failures.
