Leadie,
My observation is that the bad habits are often taught (or allowed to form) in the sausage factory schools purporting to be airline academies... However, I note this is more a function of the individual instructor than the school in probably most cases - the big schools tend to be inundated with very low time instructors who are ignorant of the training standards required and simply chop through a syllabus.
The much vaunted time in the bush is invaluable for experience, problem solving and command development skills - but must be accompanied by good mentoring if its value is to be realised / maximised and the bad habits from the flying school are to be fixed.
I can’t imagine QF is the place to be teaching these kids a basic crosswind technique, or IAP profile management. Not when I’m in the back enjoying a beer, anyway!
