Not really. Manning a carrier and making sure the carrier is in the best condition, those are two of the most important issues you have. As I said, they have largely started their naval aviation training, obviously they are in a much better position compared to 20 years ago, let's say, when they didn't have any carriers. From what I have observed, via video, reports and in Chinese language forums, is their carrier group tactics are evolving quickly, quite better than most other militaries and navies with carriers. It's to be expected, China usually rapidly develops and they have been doing it increasingly more consistent and well. It would likely take China less than a decade.Manning and maintenance is the least of the issues. Naval aviator training and Carrier Group tactics is what really matters. Training to fight in the darkness of the night, in thick fog, in chilly winter with ice particles on deck, in heavy rain, in rough seas... naval aviation skills take time to master. Same goes for Carrier Group tactics. Cruising under strict emissions control, using obscurants to play hide-and-seek with enemy satellites, breaking formation when required, evaluating the constantly changing threat axis, surveying the battlefield around in all three domains (air, surface and sub-surface) at the same time... these are not easy skills to master and something you learn in say a decade.
And then there's the training difference between CV and CVN. CVN is an entirely different beast to a CV and opens up so many tactical possibilities that arrive with unique training requirements of their own.
Reactor safety, reactor ops, flight deck ops, damage control, security drills, etc etc, those are all major differences in a CVN versus a CV, true. Though I listed more operational training, tactical possibilities are very different as well.
