IMHO the use of checklists is to ensure that nothing Vital is missed in the preflight phase. This surely must apply to any type of craft that is going to be taking to the sky. I have seen/watched numbers of GA pilots who's idea of a preflight check is to undo the tiedowns. We live/operate and work in a safety culture, and what better way of reinforcing good practices can we offer aircrew. Complacency often kills. Furthermore, the pilot who posted the message was looking to be "professional", and this is to be applauded, not denigrated. If such a professional attitude is learned early, then the transition to bigger/larger aircraft is eased, especially in an Multi Crew environment.
The defence rests.
