737 Load Manager - how to get it to effect flight?

Dear All:I see how to use the load manager for simulating weight & loading the aircraft, but how does one take those numbers & actually get them loaded into the aircraft so it effects the handling of the aircraft? I just use it in my planning, as not to over stress the aircraft, but in reality, the plane handles no differntly because I can't control the weight distribution where the passangers actually sit in my plane once I load the sim - can I? In short, after using the load manager, I can more or less pretend to have a loaded plane with my new found numbers from the load manager, but how do I astually get the plane to BEHAVE as if the cargo & passangers are REALLY sitting where the load manager says they are? The closest I can get is to copy the payload & fuel numbers into the fuel & load-out menu of the sim. Any ideas?Also, is there a way to put passangers in individual random seats & not just fill the plane umiformly from front to back? Can I sporadically put passengers wherever I want in the load manager, & maybe have empty individual seats wherever I want?Lastly, is there a place in themanuals to read in detail about the Load Manager?Chris Catalano
