As I joined FedEx, I was told that they had already worked out sensors, of some kind (I never saw details), on the landing gear that would give the data needed for knowing and controlling weight and balance. For balance, right, e.g., don't want all the weight near the tail and, instead, want the weight more evenly distributed in the cargo area along the length of the plane, that is, want the load in balance. So, yes, FedEx did think of having sensors, of some kind, in the landing gear. But I never heard more about such sensors, and, for the times I rode the jump seat in the planes, I never saw pilots working with weight and balance from data from the landing gear. Maybe later, after I went to grad school, FedEx did do something with such sensors. So, right, the sensors are a good idea and were considered and, maybe, eventually implemented.
