This whole discussion was one of the reasons that I proposed a different way of qualifying as an instructor (see threads following GAPAN Forum at RAF Cranwell) plus the establishment of an International Flying Instructor Association. I have been instructing for over 12 years and still only get paid £12.50 per hour if I do PPL instructing. I think this is a shameful failure to acknowledge experience and I find it disappointing that the Airlines, who are the net beneficiaries of the whole training system, do little, if nothing to support the training industry. We need something akin to a union to campaign for our rights as instructors and to protect us as there are many instances where insurance does not cover our activities and many people are not aware of this deficiency.
