UAVs have become increasingly popular, with applications ranging from aerial photography and express delivery to power line inspections and disaster relief. These devices are now present in almost every industry. According to a well-known consulting firm, Gartner, the production and sales of drones are expected to grow by 39% in 2017, reaching 3 million units, with global market revenue projected to reach $6 billion. However, this rapidly growing industry faces numerous challenges, particularly concerning safety. One of the main issues is the security risks associated with "Black Flying," where unauthorized drone flights have caused disruptions at airports across the country, leading to flight delays and even incidents like a drone flying close to an aircraft. Current laws and regulations remain unclear, and drone oversight is still in a gray area, raising concerns about their impact on aviation safety.
To address these issues, DJI Innovation, a leading player in the industry, has taken proactive steps. On March 2nd, the company introduced a new polygonal no-fly zone strategy, making the restrictions more flexible. Drones will be prevented from taking off within the no-fly zone and will automatically slow down and hover when approaching the boundary. This update will first be implemented at airports in mainland China before being rolled out globally.
The new no-fly zones include a circular area with a radius of 4.5 km around each runway, forming a flat ellipse. If a drone enters the no-fly zone without GPS signal, it will automatically land once the signal is restored. In addition to the no-fly zones, there are also flight-limited zones at 30m, 60m, and 120m altitudes. For example, the 60m zone is a trapezoidal area extending 15 km from the runway with a 15% slope, ensuring it doesn't overlap with other restricted areas. When a drone approaches these zones, the app will alert the user, and if the altitude exceeds the limit, the drone will automatically descend.
DJI’s approach represents a shift from previous circular no-fly zones to more flexible polygonal ones, allowing for better balance between safety and usability. Shao Jian, vice president of DJI, emphasized that this change was made early on to ensure both aviation safety and user freedom. While recent security incidents may have accelerated the development of these policies, DJI believes in taking responsibility and acting ahead of regulatory processes.
Industry experts like Ke Yubao from AOPA acknowledge DJI’s efforts, noting that drone safety remains a major concern. Discussions on electronic fences and flight control codes are ongoing, with many stakeholders involved in shaping future regulations. DJI also plans to integrate ADS-B technology into its drones, allowing them to detect and avoid manned aircraft, further enhancing safety.
In addition to technical solutions, DJI advocates for a self-contained management system for drones, similar to railway or highway systems. The company encourages the establishment of industry standards and government-led education programs to promote responsible usage. Meanwhile, Ke Yubao suggests that while regulation is important, it should not hinder innovation. Instead, a balanced approach that considers both public safety and user needs is essential.
For safe flying, DJI recommends checking the drone's propellers and battery, ensuring proper GPS signal, and avoiding crowded areas. Public safety measures include staying away from buildings, power lines, and signal towers, as well as maintaining visual contact with the drone.
To check no-fly zones, users can visit the DJI website and access the "Safe Flight Guide" section, where they can find detailed maps and restrictions. This feature allows users to input their location and receive real-time updates on flight restrictions.
Overall, DJI's new polygonal no-fly zone strategy marks a significant step forward in drone safety, demonstrating the company's commitment to responsible innovation and collaboration with regulators. As the industry continues to evolve, such measures will play a crucial role in ensuring the safe integration of drones into our skies.
