It depends who is the shifter.
What I mean by that is that if it is your fright, as in the companies freight, then it falls under the private Cat, but if some one came to you and wanted to pay you in shifting his fright, then it falls under the Public transport Cat.
A very simple example.
I believe that when the CAA approve the Caravan or any other Turbine Single Engine aircraft it will be Freight first, for a couple of years, as the Americans did 300 years ago.
