I just had to cover because a local school had been so desperate they took on an instructor before he had finished his course. Weather delayed him so they had booked a few lessons in for him, I was at a loose end waiting to start training for my next job, and was asked to help out. They want me to get back in touch if I can work at all over the summer, as they anticipate a need for instructors.
While I have some experience as an instructor, they clearly were also looking at someone so inexperienced he wasn't yet qualified! I am not sure who you are talking to Whopity. Are they actively looking for work? Do they have personality for the job?
Agree that it should be possible to instruct with a PPL without recourse to CPL exams, and think anyone instructing should be paid, regardless of licence. The system was not broken, why did JAA have to fix it?
