Mason, it is entirely logical that Ryanair get a kickback for the TR. Ryanair themselves determine the price for the TR and they were responsible for the latest price increase rather that CAE.
If you look at the evidence, it is mostly Ryanair F/O's that are instructing. They are paid by Ryanair (or Brookfield) and so all Ryanair do is hire the sims from CAE. Now Ryanair would be quite foolish to allow CAE pocket €33k odd for the hire of the sims and a few weeks of ground school.
Secondly, Base training is carried out by Ryanair which is part of the TR. Obviously this is also a substantial cost which Ryanair are fully reimbursed for. I've no ideal how much money they make out of running TR courses but from what I've been told CAE make very little out of it.
