The link above mentions some pilots to aircraft ratios. 85 aircraft on Kitty hawk and 110 pilots. (This one may be counting pilots in a peculiar way)
And 120 pilots on Nimitz in 1999 for 3 units of f18, one f14 unit, one prowler unit, one s3 viking unit, one hawekye unit, one helicopter unit and one c2. My assesment of aircraft numbers for that would be between 72 and 78 aircraft. Some 37 of them with two pilots.
By googling one can find about french depoloyment on Nimitz from a few years ago. 27 pilots, 12 rafales and 1 Hawkeye.
Thus, rough estimate would be 1.5 to 2 pilots per seat on a carrier deployment, though some of these examples go even lower to 1.1 per seat. Again, who is to say what standard for counting was used.
We also have Henri K. And his assesment of certified pilots for j15. In October 2017 he wrote that 7th generation of pilots was certified. And that there should be between 29 and 36 pilots certified. And his graphs guesstimate future pilot numbers for j15 programme. By late 2019 he expected between 36 and 56 pilots to be certified.
Anyhow, if we assume average figure of 46 pilots, that may be enough for 23 to 44 planes. Some of those would be instructors for twin seat trainers. But roughly speaking there may be enough pilots for some missions, between 20 and 40 of them, depending on demand of the campaign requirements.
Henri k. Further guesstimates that further 10 to 15 pilots per year will be certified through the coming several years.
I dont comment on accuracy or plausibility of any sources I mentioned here.
