Drones have become increasingly popular, with applications spanning aerial photography, package delivery, power line inspections, disaster relief, and more. They 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. Despite this rapid growth, the emerging industry faces numerous challenges. One of the most pressing issues is the security risks associated with "black flying"—unauthorized drone flights that threaten public safety. In recent years, drones have frequently entered restricted airspace near airports, causing flight delays and even incidents at airports in Shenzhen, Hangzhou, and Xining. A viral video showed a drone capturing footage of a commercial aircraft, raising serious concerns about aviation safety.
Current regulations and oversight for drones remain unclear, leaving them in a legal gray area. The challenge of managing these devices has become a critical issue. In response, DJI Innovation, a leading industry player, has taken proactive steps. On March 2nd, the company introduced a new polygonal no-fly zone strategy, offering more flexible restrictions. Drones will not be able to take off within the no-fly zones and will automatically slow down and hover when approaching the boundaries. This update will first be implemented at airports in mainland China before being rolled out globally.
The new no-fly zones are designed with precision. At each airport, a circular area with a 4.5 km radius around the runway ends forms the no-fly zone. If a drone enters without GPS signal, it will automatically land once the signal is restored. In addition to no-fly zones, there are also flight-limited zones set at 30 meters, 60 meters, and 120 meters. For example, the 60-meter zone features a trapezoidal shape extending 15 km from the runway with a 15% slope, ensuring it doesn’t overlap with other restricted areas. When approaching these zones, users receive warnings, and the drone automatically adjusts its altitude to comply.
This is not the first time DJI has introduced such measures. The company has long considered regional restrictions based on ICAO and national air traffic control guidelines. However, the new polygonal approach offers greater flexibility compared to previous circular zones. As Shao Jian, vice president of DJI Innovation, explained, the goal is to balance safety with user experience.
The release of these updates was partly driven by recent security incidents, including the controversial high-altitude drone footage of an aircraft. While DJI acknowledges that regulatory development is ongoing, it emphasizes the importance of taking responsibility early. As Shao noted, waiting for government decisions is not always feasible.
Experts like Ke Yubao from the China Aircraft Owners and Pilots Association (AOPA) agree that drone safety is a growing concern. Discussions on electronic fences and flight control codes are already underway, with many stakeholders involved. Ke believes that while regulation is necessary, it must be balanced with education and awareness.
Looking ahead, DJI plans to integrate advanced systems like ADS-B receivers to detect manned aircraft and avoid conflicts. Shao envisions a future where drones and traditional aircraft can coexist safely, requiring both technological innovation and policy refinement.
In conclusion, drones need a self-contained management system—similar to railways and highways—to ensure safe and orderly operations. While legislation is still evolving, companies like DJI are setting the pace, pushing for better standards and safer skies for all.
Drop Out Fuse Cutout is a kind of outdoor high voltage protection device, lt is connected with the incoming feeder of thedistribution transformer or distribution lines and primarily used to protect transformers or lines against the impact raised by shortcircuit, overload and switching current. The drop-out fuse cutout is composed of insulator support and a fuse carier, staticcontacts that are fxed on two sides of insulator support and moving contact installed on two ends of fuse carrier, The interior ofthe fuse carrier is the extinguishing tube while the exterior is made of phenolic compound paper tube or epoxy glass.
