This report details the results of a study that has been completed to assess the risk of High-Intensity Radiated Fields (HIRF) to fixed-wing transport and nontransport aircraft in the U.S. The approach to the assessment of HIRF included the following elements: Detailed information of 893 emitters and 5913 flights near Denver and Seattle; Quantitative judgements from industry experts about onboard avionics with regard to type, properties, and response probabilities; and Electromagnetic environment levels from regulatory and standard sources DO-160B, DO-160C, and the proposed Notice of Proposed Rulemaking (NPRM). Certification field strength levels from the proposed NPRM, DO-160B and DO-160C were used to calculate the probability of a HIRF-induced catastrophic aircraft event. No clear evidence was found that flights in the Denver and Seattle areas experienced a HIRF environment level greater than the NPRM certification levels. The probability of the HIRF-induced catastrophic events are presented as a quantitative assessment of the HIRF risks to aircraft safety.
