Basically they held the largest air force mock combat exercise this year, and the results were overwhelmingly in favour of J-11. The training exercise was similar in scale to American's Red Flag. One particular J-11 pilot managed to accumulate over 42 mock kills over its J-10 opponent while only being "shot down" once. It's interesting since the results were complete reverse of just a few years ago when J-10 always manage to gain the upper hand. The past two years, units flying the J-11 has consistently outperform their opponents.
