Ace the A/C Ground Group II – ERJ Challenge 2025: Soar High with Confidence!

Question: 1 / 400

What does electromagnetic interference (EMI) refer to in aviation?

The measurement of electrical currents

The disruption of electrical circuits due to external electromagnetic fields

Electromagnetic interference (EMI) in aviation refers specifically to the disruption of electrical circuits caused by external electromagnetic fields. This interference can emanate from various sources, including electronic devices, natural phenomena like lightning, or other aircraft systems. These external electromagnetic fields can induce unwanted currents and voltages in the aircraft's electronic systems, potentially leading to malfunctions or degradation in performance.

Understanding EMI is crucial for aviation safety, as it can affect navigation systems, communications, and flight controls. By identifying EMI as this type of disruption, engineers and pilots can implement measures to shield sensitive systems or create protocols for the use of electronic devices on board to minimize the risks associated with electromagnetic interference.
