EMI can affect which systems?

EMI can affect which systems?

• A. Radar
• B. Flight controls
• C. Air conditioning systems
• D. All of the above

Answer: (D)

EMI stands for electromagnetic interference, and it can couple into electrical and electronic systems in many ways. In an airplane, radar relies on delicate RF signals and processing, so interference can obscure targets or create false returns. Flight-control systems, especially modern electronic or fly-by-wire setups, depend on accurate sensor data and clean command signals; EMI can inject errors or disrupt control messages. Air conditioning systems use electrical motors, sensors, and controllers, and EMI can cause motor noise, faulty readings, or control glitches. Since EMI can affect any electronic or electrical subsystem, the most accurate choice is that all of these systems can be affected.
