I just wonder how they work out the max weight? For example if you fly 50lbs overweight in say an R44, however are flying in a straight line are you not puting less strain on the various components than if you are at max weight and doing lots of banks and turns. So I wonder how they come up with the figure. I doubt if an R44 flew continual figures of 8 at 60 degrees that they would ever reach 2200 on the appropriate components. It tends to suggest that somewhere someone is puting their finger in the air and using the laws of average, perhaps thats why many pilots do fly overweight, thinking they can get away with it
