View Rule

This rulemaking would permit operators to use an EFVS in lieu of natural vision to continue descending from 100 feet height above runway touchdown zone elevation to the runway. This action would also permit certain operators using EFVS-equipped aircraft to dispatch, release, or takeoff under instrument flight rules (IFR), and to initiate and continue an approach, when the destination airport weather is below authorized visibility minimums for the runway of intended landing. Pilot training, recent flight experience, and proficiency would be required for operators who use EFVS in lieu of natural vision to descend below decision altitude, decision height, or minimum descent altitude. The FAA believes that an EFVS can provide operational and safety benefits during Category II and Category III approach operations. The rulemaking would enable expanded EFVS operations, which would increase access and efficiency in low visibility conditions, and potentially result in fewer missed approaches and delayed take-offs.
