Reasons for Drone CrashesHere are the main causes of drone crashes that heliguy™ have experienced.
Loose or Damaged PropsOver the years, props have been improved dramatically and are much hardier and easier to fit than on earlier aircraft. However, losing a prop during flight is still possible and can be potentially deadly to your aircraft, either if it hasn’t been installed properly or damage has not been noticed before beginning your flight. Check your props for any damage and replace if necessary before every flight. Props are one of the cheapest aspects to your drone so make sure they're kept in working order. Further to this, check they’re on tight and free to spin before any flight. This is a quick thing that could save your drone from a dangerous crash. It's worth including the above in your pre-flight checklist to make sure you don't ever forget. Top Images - DJI M600 & Bottom Images - DJI Phantom 3
Flying BackwardsFlying your aircraft backwards can achieve some amazing shots but, you should only do so when you’re an advanced pilot and can do so competently in order to keep your drone safe. When flying backwards, scout out the area and use a spotter whenever you're able to. This will help you keep an eye on your drone and allow you to fly your drone and avoid crashing into any obstacles such as trees or telephone lines. Keep in mind, even the most advanced pilot can miss smaller obstacles, especially when flying their drone further away from themselves. Also, keep in mind, drones with obstacle avoidance rarely have sensors on the back so you are solely relying on the human eye to see any obstacles, big or small.
Indoor flyingFlying indoors usually results in your aircraft receiving no GPS or GLONASS signal putting full control over the drone on the pilot. Unless flying in a building like an open and clear warehouse, you’re likely to be surrounded by obstacles. If your aircraft has obstacle avoidance sensors, these will be hypersensitive and try to avoid any obstacle they can sense, possibly moving your drone into another obstacle such as the ceiling of the room. Ensure you’re an experienced pilot before flying in doors and be extra vigilant to avoid any collisions. DJI Spark
Stopping DistanceAlways remember to take into account the stopping distance of your drone when flying as your drone won’t suddenly stop when you hit the brakes. Like with any vehicle, the stopping distance is affected different factors. With a drone, you must consider your speed and the wind speed and how they will impact on the time it takes for your drone to brake. If you're flying quickly, especially in Sport Mode, you need be extra vigilant with the expected time for your aircraft to stop. It's also worth noting, when flying in Sport Mode, most drones obstacle avoidance sensors are inactive. Avoid flying at high speeds when around obstacles as it will take longer to stop or change the direction of your aircraft.
Ignoring warning messagesTechnology in drones has advanced to the point where they are designed to keep themselves as safe as possible. Features such as Return to Home and obstacle avoidance sensors are probably the first that come to mind but you need to pay attention to the warnings messages within the apps you use to control the aircraft. These include low battery notifications, weak remote controller connection, weak GPS signal and a great deal more. The warning features are put in by drone manufacturers to help you fly as safely as possible and take the pressure off the pilot. Pay attention to them help avoid crashing your drone for a reason that could have easily been avoided. DJI Go 4 Screenshot
Flying in adverse weatherDifferent weather conditions can have a huge effect on how your aircraft behaves and how you should control it. Although some drones are protected against the weather like the DJI M200 series, most will experience issues if flown in wet and rainy situations. Make sure you check the weather forecast before each flight and include it within your pre-flight checklist. Always visually monitor the weather for any changes in wind or signs of rain and fly within yours and your aircraft’s limits to avoid any potential crashes caused by the weather.
CSC (Combination Stick Command)A combination stick command can be used to power-off the motors following your aircraft's flight, however, this is not recommended as it may cause your aircraft to flip. It is done by moving both sticks down and into the center. Inexperienced users may accidentally complete a CSC during flight which will turn off the drone’s motors and cause the aircraft to fall from the sky. It’s only recommended that a CSC is used in an emergency when there are no other options. Other than this, it’s recommended that a CSC is avoided.
General AdviceFirstly, read your instructions as soon as you receive your drone. With companies like DJI, you can read these online so if you really can't wait, download a copy before you get your aircraft. Learn the functions of different modes and how they will affect your specific aircraft and don't assume anything. After reading the instructions, spend a couple of hours in the flight simulator rather than jumping into flying. Getting your first drone can be a very exciting time but you need to learn the basic mechanics of flight before risking your aircraft. Using the flight simulator helps you learn how to use controls that you've likely not experienced before and will help you avoid making a silly and costly mistake that could have avoided. Following flying in the flight simulator, it’s recommended you fly in a location free of obstacles to avoid collisions such as a field. Take it slow and learn how to control the drone in a real-world setting before taking on advanced flights. See how factors such as a light wind can affect the aircraft and learn how to fly with this in an area where you can't bump into anything. Always remember to fly within your capabilities as a pilot. As you develop, you will be able to take on more complex flights but only do so when you're fully competent. Always keep your firmware up to date to ensure your drone has the latest technology which can include additional safety features. For added safety and ensure your drone is ready for flight, always remember to complete a pre-flight checklist. This will help to ensure both you and your aircraft are completely ready for flight.
