These flights will be much safer, even if they are 'violations'. Just getting used to Two Crew Ops earlier than other countries.
Two crew ops has no relevance in the PPL where most solo flight occurs. How can it be safer to release a pilot who has had no opportunity to practice decison making whilst at the same time gaining self confidence in their ability to do what they have been trained to do? If they fly with a comfort blanket then their first passenger will be the next comfort blanket. Flight instruction encompasses Demonstration, Teaching and Practice, to deny the student the opportunity to practice is poor teaching as well as being fraudulent.
Some years ago I came across an East African VC10 pilot who had never flown solo in his life!
