During an extreme solar particle event or geomagnetic storm, however, the radiation environment can change within minutes or hours. Modern avionics are designed to withstand routine radiation environments, but extreme space weather can push systems beyond the conditions used in conventional certification and reliability testing. Subject of Research:The effects of extreme space weather on aviation radiation exposure, aircraft electronics, flight safety and operational decision-making.
