Revisions to Operational Requirements for the Use of Enhanced Flight Vision Systems (EFVS) and to Pilot Compartment View Requirements for Vision Systems; Correcting Amendment

The FAA is correcting a final rule published on December 13, 2016. In that rule, the FAA amended its regulations to allow operators to use an enhanced flight vision system (EFVS) in lieu of natural vision to continue descending from 100 feet above the touchdown zone elevation (TDZE) to the runway and to land on certain straight-in instrument approach procedures (IAPs) under instrument flight rules (IFR). As part of the final rule, the FAA revised appendix F to part 121 to provide greater clarity on the checking requirements for EFVS. In amending appendix F to part 121, the FAA used amendatory instructions that inadvertently misplaced new paragraph III(c)(5). This document amends appendix F to part 121 to correct that error.
