I take notice of this subject as a matter of my personal interest, In tas because we are small in number and our groups are small in number as well, our influence on one another is greater. This comes from the cfi down not the other way around. I have not found one single person who didn't know mtow off the top of their head [remember it has to be placarded on the dash] nor have I ever found anyone flying over wieght. [ I have not be cheeky enough to suggest to someone we weigh the contents of their plane yet] If the cfi sets the standard others follow. I'll bet in Merv's little circle of of students, bfr returns, worshipers he does not need to constantly retrain them because they allow their standards given to them by their instructors to drop away between bfrs. It is my belief that a reminder from time to time of a pilots responsibilities is a far better tool than a mallet
