Introduction
The interaction of electrical and magnetic fields emanating from systems within an aircraft, or the interaction between the aircraft and the external environment, can create unwanted effects, which may adversely impact the safe flight of Defence aircraft. Protection of Defence aircraft designs against Electromagnetic Environmental Effects (E3) therefore must be established as part of initial design, subsequent modification, ongoing maintenance, and any time an aircraft or system experiences a change in its Configuration, Role or operating Environment (CRE).
