> Federal officials subsequently issued new rules for nighttime landings and control-tower staffing. Now, when an adjacent runway is shut down at night, air traffic controllers will no longer let pilots make so-called visual approaches to land. Instead, they must use instrument landing systems or satellite-based systems to line up for the correct runway.

Not sure this supports that "unambiguous language" is the problem. To me it sounds like the problem is "humans being expected to perfectly perform routine tasks" - and the solution is to move as much of the task away from the humans as possible. I imagine there are parallels in the medical system (but am not expert).
