According to the 2015 legislative plan of the National People’s Congress, China has set out to stipulate Aviation Law and modify Civil Aviation Law. The protocols for the two laws mentioned above are repeated and crossed in legislative purpose, legislative content, management functions, management issues, and many other aspects. The positioning of the two laws and the division of scope are not clear. The construction of the aviation legal system is defected in scientific division of scope. The two laws should be repositioned to clarify the legislative purpose and divide the adjusted contents reasonably.
