One of the space weather hazards is the sudden occurrence of cosmic radiation exposure due to high-energy protons associated with massive solar flares. This paper focuses on cosmic radiation exposure for airline crew members, explaining the mechanisms and current regulations. Additionally, it introduces an overview of the recently developed Aircraft Radiation Exposure Warning System (WASAVIES) in Japan.
