Yes definitely of course should be a profit.
For the PBN in this case you should have it now in the licence since it is mandatory, for the other course as you said, it is including inside the 30000 I believe.
If they can make some profits are the salary for the instructor and the engineer to run the simulator and the various courses.
I don't think they can make a lot of extra enough to run the entire airline.
That was years ago with the scheme PAY-to FLY. Where the people have to pay money during the line training and also after it.
In this case fortunately they are " paying " us during the line training.
At least is something very different. Don't you agree?
