What characterizes intermittent failures in avionics systems?

Intermittent failures in avionics systems are characterized by unexpected loss of information. This phenomenon typically occurs because intermittent failures can result in sporadic signal disruptions or communication failures between various components of the avionics systems. Unlike consistent performance, which implies a stable and reliable operation, or persistent errors that are ongoing and repeatable, intermittent failures manifest sporadically, leading to temporary lapses in data transmission or system response. Additionally, frequent complete system shutdowns would indicate a more severe and sustained failure mode rather than the transient nature associated with intermittent issues. Therefore, the loss of information aligns closely with the unpredictable and non-continuous nature of intermittent failures.
