I understand the link and thank you.

But how is a carrier undetected when carrying out air operations? Or is it impossible to hide during air operations?

As to how to hide a carrier during flight operations, I have no idea. I found this Hiding in Plain Sight—The U.S. Navy and Dispersed Operations under EMCON, 1956–1972. While it covers a historical period, the first few pages show that for the Navy these questions and efforts to solve them are not new.
