High intensity radiated field (HIRF) external environments for civil aircraft operation

Recent years have witnessed the use of electrical/electronic systems, Potential increase in susceptibility of integrated circuits due to increased operating speed and density, Possibility of reduced Electromagnetic (EM) shielding afforded by composite materials, external RF environment will become increasingly severe due to an increase in the number and power of RF emitters. In this paper Rotorcraft Severe, Fixed Wing Severe, Certification and Normal Environments that civil aircraft may be exposed to while operating are presented.
