So the problem is indeed with the training program.

You design the training program based on your "targeted audience". For example, the regionals know that they are someone's first airline job, first jet, first multi-crew airplane, first high-altitude airplane, first RVSM, first FMC, first EFIS, first transport-category airplane. So their curriculums are designed for people like that.

If Atlas designed the 777 curriculum for ex-Emirate CAs, then Atlas should be hiring ex-Emirate CAs or the like. If they are not, then they need to redesign the curriculum.
