When was the last time you saw anyone check the T/W of an aircraft? We don't have people enforcing the rules we have NOW.. What makes you think anyone will enforce any future rules?
Doug,
The Mississippi Gang tried this a few years ago and it was so inconsistent it was ridiculous. You could take the same airplane and use two different methods and get two different values. You could check the airplane on two different days and get slightly different readings as well. The rules have to be enforcable for them to have any teeth. Over the course of the last year I know of several pilots that have been approached by other pilots about "unsafe" flying and in all of the cases the pilot toned down their flying. What may seem unsafe to some may not to others. The community as a whole seems to be policing itself very well.
