No. My first regional training program (a couple decades ago) was all systems, limitations and profiles. A whole bunch of ASEL pilots who got nothing on swept wing aerodynamics, high alt aero, high alt wx, turbine engine theory, etc.

We could all tell you EXACTLY how many rotor and stator stages the engines had on each end of each spool, and could draw the fuel delivery system from memory. But how that engine would behave near or outside the envelope? Nada. Well we did talk about that a little, but only because somebody had just crashed a jet.

This was an era when regionals (rapidly) were transitioning from turboprops to jets, and it showed.

Yes, you'll get all of that in new-hire training but it will won't be the main event, you'll blow through some CBT's (or maybe your autoclicker will) because you're focused on memorizing profiles, lims, mem, and KV items.

It exists because the regionals can't be trusted to cover it adequately.
