Typical activities in this field include UAV logistics distribution, air tourism, leisure activities with light aircraft, aerial photography, agricultural monitoring, urban air traffic management, etc. The rise of the low-altitude economy is due to the rapid development of UAV technology and other vertical take-off and landing aircraft technology, which provides new possibilities for a variety of commercial activities. With the continuous opening of low-altitude airspace, more and more low-altitude flight activities will be carried out, but the industry is also facing many problems as it rises.
