At the 9th World Drone Conference, Peng Liwu, vice president of Qifei Aviation, said that the bottleneck in the field of eVTOL manufacturing technology no longer exists, and the shortcoming lies in the power system. The energy supply problem is expected to be solved within the next five years. He believes that the low-altitude economy is returning to rationality, and 2025 is the year for re-evaluation of the industry. Peng Liwu pointed out that China will have an advantage in the global low-altitude economy with its supply chain and manufacturing costs. In addition, he also mentioned that eVTOL manned commercial operations require multiple certificates, and the shortcomings of the power system are expected to be resolved within 5 years. Peng Liwu said that under the guarantee of a mature aviation industry manufacturing system, the company's parts procurement costs are very competitive. "In the field of low-altitude economic manufacturing, China's manufacturing costs are only one-fifth of those in the United States. In the future competitive track, China also has obvious advantages in engineering landing. This is the biggest confidence in the development of China's low-altitude economy."
