Aircraft EMI shielding is the practice of protecting sensitive avionics from electromagnetic interference generated by internal and external sources. It utilizes materials like conductive coatings or metal shielding to block or absorb unwanted radio frequency signals, ensuring operational integrity. Conductive coatings and lightweight absorbers are increasingly preferred over heavier metal shielding for modern airframes. The commercial aviation sector constitutes the primary end user, but the UAV segment represents the fastest-growing market due to its dense electronic payloads.

Compliance with standards such as the FAA's regulations, the European Union Aviation Safety Agency's directives, and military specifications like MIL-STD-461 is mandatory for market access. These frameworks dictate the required attenuation performance and environmental testing for all shielding components on an aircraft. Material selection decisions will increasingly balance electromagnetic performance against weight, cost, and resistance to harsh aerospace environments.
