EMC/EMI Training for Aerospace
Regulatory compliance and due diligence require that electronic devices undergo testing for electromagnetic compatibility.
EMC (electromagnetic compatibility) and EMI (electromagnetic interference) figure prominently in regulatory testing and compliance.
The testing generally falls into one of two categories:
- Immunity testing – Measures how a device will react when exposed to electromagnetic noise and other disturbances. The purpose of these tests is to gain a reasonable assurance that the device will operate as intended when used within its expected operating environment.
- Emissions testing – Measures the amount of electromagnetic noise generated by a device during normal operation. The purpose of these tests is to ensure that any emission from the device are below the relevant limits defined for that type of device. This, in turn, provides a reasonable assurance that the device will not cause harmful interference to other devices operating within its expected operating environment.
Testing is particularly significant to airplanes and other airborne crafts because of their proximity to storms and the elements. Their positioning at high altitudes also prompts rigorous inspection so they reach their destination without component failure.
Additionally, frequency-generating devices like radars and radio networks are abundant in aircraft. Maneuvering through weather and observing surrounding changes entails an assortment of data-collecting machinery. Receivers, analog or wireless synthesizers and telemetry are instrumental in safe traveling. They all need to engage seamlessly without expelling or picking up harmful currents.
Avionic control systems as well support the orientation of aircraft as they ascend, roll, rotate and land. These movements take special aerodynamic considerations, and the control systems can receive commands from an electronic interface and computing, which opens the possibility of EMI.
Aerospace crafts also have EMC requirements, although they add in launch and exploration applications. The Air Force Space and Missile Systems Center’s Standard SMC-S-008 ensures that space projects prioritize EMC and avoid EMI malfunctions. EMC testing for aerospace initiatives includes integrated hardware and systems for airborne and space-directed vehicles. Lightning, HIRF and shielding in transportation are useful to aerospace operations.
For a systems engineering, it’s crucial to consider electromagnetic compatibility and interference in design. Failure to do so in the early stages of product development can cause considerable expense and wasted time. Electromagnetic incompatibility requires a redesign in later stages in order to comply with EMC/EMI specification tests and avoid safety risks or product failure.
Evaluating how a device will react when exposed to electromagnetic energy is known as susceptibility or immunity testing and involves determining the ability of a device to tolerate noise from external sources.
Often, systems engineers and project stakeholders find industry regulations regarding EMC/EMI specifics downright confusing. A lot of this has to do with the different requirements in the U.S. and the European Union (EU), as well as differing interpretations of the meanings of EMC and EMI.
In general, the device’s intended application will determine the exact type of testing required.
