There are a myriad of ways companies could develop and implement internal controls. I have no particular knowledge that would make qualified to proclaim the single best way for handling these problems, but from a historical and empirical standpoint, the world is full of examples of companies solving complex problems previously thought to be too difficult by the majority of people.<p>&gt;Something automatic?<p>You seem to be assuming pilots and passengers have no regard for their own well-being. Just like the discretion shown by the OP in their story about canceling a flight, pilots have strong incentives to not fly if there is an increased likelihood they can&#x27;t do so safely. I would see the &quot;automatic&quot; aspect likely being conditions which prohibit flying while even further discretion still being available to pilots.
