I want to know the answer to the following question:
Why did the Chinese PLA Navy need 4-5 years for Liaoning to reach full capacity?
All the background I'm provided with is that "On 26 December 2012, the People's Daily reported that it will take four to five years for Liaoning to reach full capacity, mainly due to training and coordination which will take significant amount of time for Chinese PLA Navy to complete as this is the first aircraft carrier in their possession.". Is that enough to answer the question?
Answer: yes
