And after they have passed the test what then they go off unsupervised solo or with innocent pax onboard.
Far better they get there PIC skills up under supervision than not.
I don't train for tests they are the lowest standard which I will accept.
If the person wants more training than the minimum required then they can have it. I have no doubt that some will say well do the test then they can do any extra they like.
But realistically they will gain more from flying solo in the circuit that having a big lump sitting next to them. They just need the old wiring opened up to get the touch back.
