International audience The objective of this work is to investigate impacts of solar and galactic cosmic rays on flights by considering high realistic paths issued from Flight Plan updated with Radar Data. Models and approaches used were previously validated by comparison of calculated and measured ambient dose equivalents or cosmic ray variations during quiet solar activity and GLEs. Thus, to consider continents or sub-continents representative of European international air traffic, five flights were selected. They link Paris (France) to Los Angeles, New York (United States), Tokyo (Japan), Johannesburg (South Africa) and Sao Paulo (Brazil) city. Moreover, several hundred realistic paths are considered for each of these flights. The objective is to analyze statistically the ambient dose equivalents considering path characteristics and GLE/quiet scenario, and thus demonstrate the complexity to assess the real radiation exposure, particularly during solar event.
