IEC 62396-1:2016(E) provides guidance on atmospheric radiation effects on avionics electronics used in aircraft operating at altitudes up to 60 000 ft (18,3 km). It defines the radiation environment, the effects of that environment on electronics and provides design considerations for the accommodation of those effects within avionics systems. This International Standard helps aerospace equipment manufacturers and designers to standardise their approach to single event effects in avionics by providing guidance, leading to a standard methodology. This edition includes the following significant technical changes with respect to the previous edition:
- incorporation of references to some new papers and issues which have appeared since 2011;
- addition of solar flares and extreme space weather reference to a proposed future Part 6;
- addition of reference to a proposed new Part 7 on incorporating atmospheric radiation effects analysis into the system design process;
- addition of a reference to a proposed future Part 8 on other particles including protons, pions and muons.
