## Abstract

On December 13, 2016, the Federal Aviation Administration (FAA) published a final rule to permit operators to use an enhanced flight vision system in lieu of natural vision to continue descending from 100 feet above the touchdown zone elevation to the runway and to land on certain straight-in instrument approach procedures under instrument flight rules. The FAA is delaying the effective date of this final rule.
