As for the maintenance treatment of State Grid General Aviation, I study mechanics, and I don't know the treatment there. Please ask God for an answer.

Generally speaking, the treatment of navigation maintenance is better than that of ordinary enterprises, but it can't keep up with the maintenance personnel of civil aviation, especially the skilled maintenance personnel of large aircraft. The key depends on the current benefits of the navigation enterprise you want to go to and the specific work of your personnel. Navigation is promising, and the future will focus on developing industries. If you find the right opportunity, you will develop.
