Apple,
Sure it doesn't represent all students. But my point is that if a student doesn't find their instructor professional and motivating, why shouldn't they ask to change rather than sitting there paying out shedloads of money for poor service (or worse still being put off flying for life), just because they've been advised not to show 'attitude'?
Four out of the five instructors I've flown with have been excellent and a pleasure to fly with. But I don't see why I should be expected to fork out over £100 an hour for poor service and not do anything about it. I wouldn't put up with it in any other industry, so why should flying training be any different?
