The FAA published a final rule on Tuesday that will allow operators to use an enhanced-vision flight system to descend all the way to the runway, under certain conditions. Currently, the FAA allows pilots to depend on enhanced vision in lieu of natural vision only to 100 feet above the runway, and only under certain straight-in landing procedures. The new rule requires pilots to be flying straight-in procedures on an instrument flight plan.
