A bit like the model for ice cream sellers on a beach. The first will set up anywhere on the beach, because they can. The second and All the others Will have a tendency to set up in the middle, and not down the beach, because they want a share of the same, not a reduced, customer base. This will force the 1st to the middle to recapture some of their, now, lost business (why would anyone want to walk past the middle) Because the volume to each seller is reduced so is their profit so each will trim their product lines to only the most profitable lines. (Think ALDI or Bunnings) Which is the least cost, to the registrar, aircraft? Is it 95-10 or is it the factory made plastics? If the non CASA players are facing price competition there may well be an abandonment of those classes of planes and pilot that are less profitable. Yes, the devil will be in the detail!
