Enhanced flight vision systems (EFVS) have been approved by the FAA to fly certain IFR (instrument flight rule) approaches to landing in lieu of “natural vision” from the previously allowed elevation of 100 feet above the touchdown.
Prior to this final rule, persons could only use an Enhanced Flight Vision System (EFVS) in lieu of natural vision to descend below the decision altitude to 100 feet
The new rule goes into effect March 21, 2017.
