Development of Atmospheric Neutron Single Event Effects Analysis for Use in Safety Assessments

An SAE Aerospace Information Report providing an example process for analyzing atmospheric neutron single event effects in airborne electronic systems for safety assessments.

SAE AIR6219 provides an example process for evaluating atmospheric neutron Single Event Effects (SEE) in electronic airborne systems and equipment. The report explains atmospheric radiation effects, SEE types, component sensitivity, qualitative and quantitative analysis phases, mitigation techniques, cross-section rate calculations, testing, design changes, and the integration of SEE results into system safety assessments. It includes an applied analysis example covering command and monitor functions, along with references to SAE, EUROCAE, IEC, EASA, and JEDEC publications.

Application Scope: Applicable to aerospace engineers, avionics designers, safety assessment teams, certification specialists, and organizations evaluating atmospheric radiation effects on airborne electronic equipment.
