> I wonder if it would be possible to put a weighing pad at airports for a double-check. A few modern pickup trucks have a system for measuring how much weight is in the bed or being transferred through the tongue of a trailer because of how common it is for people to overload their trucks. AFAIK these systems just use the same sorts of suspension height sensors that have been used for auto-levelling for years and are factory calibrated to know that if the rear end squats by X distance then there must be Y load in it. Seems like something along those lines would be technically easy to retrofit to large aircraft, possibly even as a software update if they already have some relevant sensors.
