Testing aircraft flight safety critical systems against the effects of electromagnetic interference (EMI) is normally performed on the ground for reasons of safety, practicality and cost. The threat and the effects of EMI on aircraft systems is discussed. The current ground test methods used at Aeroplane and Armament Experimental Establishment (A and AEE) are reviewed, including the limitations, uncertainties of measurement and safety margins. A flight test method for assessing the effects on critical systems from both the on-board and external electromagnetic environment is described which should enable the ground test results to be factored thus providing a more precise clearance for service use without compromising safety.
