Why it's crucial to perform a sensor check before every flight with the DJI Mavic 4 Pro: Checking the sensors before every flight with the DJI Mavic 4 Pro is a critical preventative measure to ensure the safety and proper functioning of the drone's automated functions. The Mavic 4 Pro is equipped with multiple visual, infrared, ultrasonic, and omnidirectional obstacle sensing sensors that enable hovering, autonomous flight, and collision avoidance. If any of these sensors experience errors or malfunctions, the drone's behavior could become unpredictable or dangerous during operation.

A proper check includes observing the DJI Fly app for error messages related to the vision sensors, compass, gyroscope, or IMU system. You should also check that the sensor surfaces are clean, free of dirt, moisture, or scratches that could interfere with reading accuracy. The accumulation of dust or fingerprints can impair the drone's ability to correctly detect its surroundings, especially when flying close to the ground or in tight spaces.

Sensors play a vital role in functions such as automatic return to home (RTH), precise hovering, and intelligent object or person tracking. A failure in any of them could cause the drone to underestimate the distance to an obstacle, fail to correctly recognize the home point, or fail to accurately follow the selected subject. Therefore, a responsible pilot should not blindly rely on automation without first confirming that the systems are operating within normal parameters.

Performing this check takes just a few minutes and can prevent costly accidents. DJI even provides calibration and diagnostic tools within the app that allow sensors to be checked and, if necessary, recalibrated before takeoff. Adopting this habit as part of the pre-flight procedure not only improves overall safety but also extends the lifespan of the equipment and reinforces the pilot's confidence in each mission.
