What should be done if the DJI Mavic 4 Pro detects electromagnetic interference during flight: Electromagnetic interference is one of the main enemies of safe drone navigation, especially in advanced models like the DJI Mavic 4 Pro, which relies on multiple signals to maintain stability and control. This interference can come from telecommunications antennas, power lines, cell phone base stations, or even large concentrations of electronic devices. Detecting and reacting correctly to these situations is vital to avoiding accidents.

When the Mavic 4 Pro's system detects high levels of interference, the DJI Fly app displays real-time warnings. The first step when faced with this alert should be to reduce altitude and slowly move away from the problem area, without making sudden movements. Changing to a safe altitude or redirecting the flight path can help restore signal quality between the drone and the remote controller.

It's important not to ignore these alerts, as interference can cause temporary loss of GPS signal, positioning instability, and flight control errors. If the level of interference persists, it's safest to land the drone immediately in a clear area and reassess the surroundings before resuming flight. In some cases, it may even be necessary to adjust the takeoff point or flight time to avoid adverse conditions.

The Mavic 4 Pro also allows you to calibrate the compass and gyroscope from the app, which is a good practice if you've experienced consistent interference on recent flights. Keeping the firmware up to date, always using open areas with good satellite visibility, and avoiding flying near sources that emit strong signals significantly reduces the risk of electromagnetic interference during flight.
