Straight-in landing operations below DA/DH or MDA using an enhanced flight vision system (EFVS) under IFR

This regulation allows pilots to descend below the published Decision Altitude/Decision Height (DA/DH) to touchdown using Enhanced Flight Vision Systems (EFVS)—essentially infrared or similar imaging technology that lets you "see" the runway environment in low visibility.

To use EFVS to land, your aircraft needs sophisticated equipment that displays sensor imagery with flight symbology on a heads-up display aligned with the real world outside. The system must show critical flight information like airspeed, altitude, flight path, and for airplanes, flare guidance.

Operationally, you must:

• Use an approach with a DA/DH (not just an MDA)
• Maintain a normal descent profile to the touchdown zone
• Be properly trained and qualified for EFVS operations
• Have FAA authorization (letter of authorization, operations specifications, or management specifications depending on your operation type)

When two pilots are required, the pilot monitoring needs their own EFVS display. This technology essentially extends your ability to continue approaches in conditions where you'd otherwise need to go missed.
