Abstract

Control Systems operating in aircraft environments can be subject to a Single Event Upset (SEU). SEU can occur when the control system is exposed to ions or electromagnetic radiation which releases high-energy particles that could potentially damage the control system and lead to a catastrophic or hazardous failure in the aircraft. This frequent SEU error can cause many challenges to meet the reliability and availability requirements of the aircraft’s system, which could pose a major challenge to meet the system’s safety criteria and certification of the aircraft system. Mitigating the impact caused by the SEU is important to improve the reliability and availability of the safety-critical control system. In this paper, the software methods are discussed to detect and correct the SEU errors and provided an example method of uninterrupted execution of control software in an aircraft control system in the event of fault detection.
