Avoiding collisions with other aircraft is critical during drone flight, especially in complex environments (such as urban airspace, near airports, or when multiple drones are flying at the same time). Drone Suppliers To ensure flight safety and reduce the risk of collisions, here are some key measures and technologies:

  
1. Understand and comply with airspace rules
Flight area restrictions: Before flying, understand local airspace rules and flight restrictions. For example, many regions stipulate that drones cannot fly within certain ranges around airports, or the flight altitude must not exceed certain limits. Using drone flight applications (such as DJI Fly, AirMap) can help view information such as no-fly zones, airspace restrictions, and flight altitudes.
Comply with airspace regulations: Make sure that the drone does not enter airspace where other aircraft are active (such as civil aviation flight areas) when flying.

  
2. Use obstacle avoidance systems
Modern drones are usually equipped with advanced obstacle avoidance technology that can automatically detect and avoid collisions with obstacles and other aircraft. The main technologies include:
Front, rear, up and down sensors: These sensors are usually based on ultrasonic, infrared or laser radar (LiDAR), which can detect obstacles on the flight path and automatically sound an alarm or slow down when the aircraft approaches an obstacle, or even stop flying completely to avoid collision.
360-degree obstacle avoidance technology: Some high-end drones (such as DJI's Mavic series, Matrice series, etc.) are equipped with multi-directional obstacle avoidance sensors that can monitor the flight environment in real time to avoid collisions with other objects.

  
3. Avoid other aircraft
Keep a visual distance: Try to keep the drone within the visual range during flight. This can help the operator better judge the position and relative distance of the aircraft, thereby avoiding collisions with other aircraft.
Avoid flying in areas with a lot of people or aircraft: If possible, avoid flying in areas with dense aircraft or complex airspace, such as over busy cities or near aircraft take-off and landing routes. Use drone flight applications to plan routes in advance and avoid known flight paths.

  
4. Use automatic obstacle avoidance and automatic flight modes
Modern drones usually have automatic flight modes, which not only help stabilize flight but also increase flight safety:
Smart follow mode: In this mode, the drone will automatically follow the target and adjust the flight trajectory, but it will still use sensors to monitor the surrounding environment to avoid collisions with obstacles.
Waypoints: When using waypoints, you can automatically fly through the preset flight route to avoid human error or deviation from the path, thereby reducing the risk of collision.

   
5. Enhance pilot awareness and operation
Stay alert: Pilots must remain highly alert when operating drones, especially in open airspace or complex environments. Pilots should always pay attention to the surrounding environment to avoid accidental collisions with other aircraft.
Use broadcast systems: Some advanced drones may be equipped with broadcast systems, such as ADS-B (Automatic Dependent Surveillance-Broadcast), which allows drones to exchange location information with other nearby aircraft, thereby reducing the risk of collision between aircraft.

   
6. Use reverse warning and avoidance systems
Some high-end drones can communicate with the flight control center and use the following technologies to avoid collisions:
Reverse warning system: When the drone aircraft approaches other aircraft or obstacles, the system will issue an alarm in real time to remind the pilot to take action.
Automatic avoidance system: Some drones are equipped with autonomous avoidance systems that can automatically change the flight path when a potential collision risk is detected.

   
7. Maintain good flying habits during flight
Low-speed flight: When flying in complex environments, you can choose to fly at a low speed, so that you have more reaction time to deal with possible obstacles or other aircraft.
Avoid sharp turns during flight: Avoid making sharp turns during flight to reduce the risk of accidental collisions.
Check the aircraft status regularly: Before and during the flight, ensure that the drone's sensors, cameras, obstacle avoidance systems, etc. are working properly to avoid collisions caused by equipment failures.

   
8. Use flight planning software
Using flight planning tools (such as DJI Terra, AirMap, Skyward) for route planning can help pilots plan paths in advance, avoid potential airspace conflicts, and ensure safer flight.

   
9. Comply with "visual flight rules"
According to the aviation regulations of various countries, drones should always maintain visual flight, that is, the operator should always be able to visually track the drone, especially when the drone is flying at a low altitude, to ensure that other aircraft or obstacles can be avoided in time.

   
Summary:
In order to avoid collisions between drones and other aircraft, pilots should follow airspace rules, maintain pilot alertness and rely on the intelligent obstacle avoidance technology of modern drones as much as possible. In addition, good flying habits, reasonable flight plans and the use of appropriate obstacle avoidance systems can also greatly reduce the risk of collision. In general, safe flight depends not only on the technology of the drone itself, but also on the pilot's control awareness and preventive measures.
