I didn't know you can instruct on a ppl now... Is the class 1 all thats needed?
It has always been possible to instruct on a PPL! You don't even need a Class 1, but you do need CPL level knowledge.
All you say is true but it fails to adress the fact that most PPL holders don't have the depth of flying experience to take on the IR with so few hours.
structured training will always be more effective than wandering around hour building when the student has no real idea what experience they are trying to accrue!
