TWT, Dropp the Pilot:
Obviously, just because something is technically possible, it does not mean that it gets adopted immediately. There is always resistance to change. But the monetary argument has been shown as been without merit in road transport already.
Stationary automatic vehicle weighing is widely implemented in road transport, no reason it cannot be done so in aviation. Price of implementation is no real hindrance. If we can employ and pay for thousands of d1ckheads as security staff at airports to supposedly ward off the 1-in-10million chance of a terrorist attack on any given aircraft, there is obviously enough money around to fund minimizing crashes due to wrongly calculated a/c weight.
