No, I have no inside knowledge. I just see a full functional carrier without birds. I think, more than one year after delivery Liaoning should sail every other week to give the pilots a plattform for training, but she is cruising with her escorts and without her aircraft. And that is not normal for my understanding, that has a reason.
May be, the J-15 isn't any longer grounded (we never know actual, what is the matter; we always look into the past). But I think it was grounded for a while or several short times. It seems to me not as reliable as expected. No surprise for a new aircraft, so the reaction of some of you to my guess is a surprise for me.
Others have already asked and you have not only not presented a single shred of evidence to support your baseless claim that the J15 was ever grounded, now you are spreading more baseless rumours about reliability problems? If wanting some evidence or proof for fantastical claims surprises you, then I think that in itself is telling.
The reason the Liaoning hasn't got a full air wing is because there hasn't been time to build one yet. You cannot just magic fighters into existence with a snap of the finger. Considering that the J15 only made their first carrier landings a few mere months ago, when the final certification of the plane was made to move it into production, to have low rate production aircraft flying already is quite a feat. Especially since the head of the J15 development team passed away during the sea trial involving the first J15 carrier landings.
The fact that time is needed to actually build the J15s is also one of the reasons why the Liaoning has spent so much of the last year in port. There is little point in her going out to sea when she hasn't got a fighter wing to train with. China has also spent a lot of time and money building a carrier simulator online, and for a lot of the basic trapping practices, that land based simulator is as good, if not better than a real carrier to help transition pilots into carrier landings.
As China builds up its J15 fleet and qualified pilot pool, you will see the Liaoning start to go out to sea more often and for longer durations, but its a gradual, steady process. That is just life, if that seems slow and unusual for you, perhaps that is because there is no 'rush build' option in real life, and as the time old saying goes, that's just life.
