It is very common in aviation. That is why at any point in time one pilot is flying the plane and another one is monitoring what the former is doing. The pilot monitoring is responsible for verifying the actions made by pilot flying not to punish or blame anyone, but just to make sure that intended action (pronounced by pilot flying) is executed correctly. It is possible that, for instance, you wanted to set value to be X but accidentally rotated a switch a little more. There are also other responsibilities of course. But, yes, making action in pairs is something critical in aviation. That does not happen often when it comes to ground software though. You need to remember that NOTAMs are user-generated content, many systems which allows pushing data to these systems are older than me. Nevertheless database maintenance is possible to do in a safe way. It’s not a DNS nor BGP - it’s high level software where tampering files is absolutely avoidable.
