Electromagnetic compatibility testing for the NASA Langley Research Center Boeing 757-200

This paper discusses aircraft-level and laboratory electromagnetic interference (EMI) testing that has been performed for the NASA Langley Research Center (LaRC) Boeing 757-200 aircraft, called Airborne Research Integrated Experiments System (ARIES). The purpose of the testing is to determine if the research equipment causes electromagnetic interference to communication receivers and/or navigation receivers on-board the aircraft. Due to the nature of the research, experimental equipment is normally required to be cleared for all phases of flight, including takeoff and landing. Therefore, interference to the communication and navigation equipment can be considered a safety-of-flight issue. Results from several tests are presented and the potential interference concerns are identified.
