What steps should the operator take if a loss of signal is detected during a Mavic 4 Pro flight: When a loss of signal is detected between the Mavic 4 Pro and the remote controller, the operator must act quickly but remain calm, as the drone is designed with automatic protocols to handle these types of situations. By default, the system will automatically activate the Return to Home (RTH) function if the signal is lost for more than a few seconds. This function causes the drone to ascend to a predefined altitude and then return in a straight line to the recorded home point. It is essential that this altitude is set correctly before the flight to avoid collisions with obstacles on the return path.

If the signal is recovered during the return process, the operator can resume manual control of the drone and redirect its trajectory as needed. For this reason, it is always recommended to practice flights with the RTH function in safe conditions to understand its behavior and limits. It is also important not to turn off the remote controller or close the app during a signal loss, as this may interrupt any automatic reconnection attempts.

To minimize the risk of signal loss, flights should be conducted in open environments, avoiding metal structures, areas with multiple Wi-Fi networks, or hills that may interfere with the direct line of sight between the drone and the controller. Additionally, keeping the remote controller antennas correctly pointed toward the drone significantly improves signal stability. More experienced users can also manually adjust the transmission channel from the app to avoid interference if the automatic option is ineffective.

Finally, after a signal loss incident, it is recommended to review the flight history from the DJI Fly app to analyze what exactly happened. If problematic areas or interference patterns are detected, this data can help better plan future flights and avoid repeating dangerous situations. Understanding how the Mavic 4 Pro responds to emergencies strengthens operational safety and pilot confidence in adverse situations.
