Drone flying has been popularized for both personal and business use. Drones can capture sky rises, magnificent landscapes, and more. However, magnetic interferences can be dangerous when flying a drone. No matter if you are flying for sport or business, it’s important to know drone safety.
Dangers of Magnetic Interference
There are many potential dangers you can face when flying a drone. The main concern for drone flyers is magnetic fields. Magnetic fields can cause you to temporarily lose control of your drone and in some cases cause your drone to crash. Drone crashes can have serious consequences depending on how and where it crashes.
Causes of Magnetic Interference
Magnetic interference can be caused by steel and electronic objects. Primarily these interferences are caused by power lines, RCC structures, concrete slabs, metal roofs, and steel structures. Luckily, there are drone apps or spectrometers that can detect magnetic interferences.
The best way to avoid magnetic interference is by properly calculating your drone’s compass. When calculating your drone’s compass, it is important to be far away from any magnetic fields. You don’t want to calibrate your drone in your car, even when it is raining. It is strongly recommended to calculate your drone in a secluded area such as a grassy field. Magnet interference will lead to incorrect compass data which may cause you to crash your drone.
Other Ways to Prevent Magnetic Interference
Preventing magnetic interference begins before your drone takes flight. Before your drone takes flight to keep an eye out for any potential magnetic interferences. To prevent your drone controller from potentially being “fried up”, which will cause your drone to crash, take precaution by encasing your drone in a Faraday cage. A Faraday cage is a closure that reduces magnetic interference.
Surfaces You want to Avoid
You want to avoid surfaces that may cause magnetic interference when your drone is taking off or landing. Be aware of hidden magnetism. For instance, you might not want to launch your drone from concrete because it may have steel rebars underneath it. Similarly, wooden tables might have hidden metal bars underneath them. It’s important to stay 50 meters or more from high voltage power lines. It’s also wise to stay away from bridges when you’re flying because bridges are often surrounded by power lines.
Precautions for Losing Control of Your Drone
In the event that you lose manual control of your drone, you want to be prepared. One safety precaution you may want to take is setting your drone’s RTH (Return to Home) to a high altitude. This will make it easier for your drone to avoid any obstacles it may encounter on its way to the home location and ensure a safe landing.
