Electromagnetic analytical modeling used to aid aircraft EMI data analysis

Determining the response of a wide variety of aircraft types and avionics installations to onboard electromagnetic interference (EMI) is extremely difficult and very costly. In-service revenue bearing aircraft are difficult to access for sufficient periods of time to conduct experiments. Subsequently, when experimental data is acquired it is often fully analyzed only well after the test aircraft is no longer available for further refined experimental analysis. Numerical models offer a solution to analyze EMI responses without major impact to in-service aircraft schedules, to aid in post-test data analysis, to help plan future tests, and to reduce costly testing
