(l) Approach to straight-in landing operations below DH, or MDA using an enhanced flight vision system (EFVS). For straight-in instrument approach procedures other than Category II or Category III, no pilot operating under this section or §§121.651, 125.381, and 135.225 of this chapter may operate an aircraft at any airport below the authorized MDA or continue an approach below the authorized DH and land unless—
(1) The aircraft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal maneuvers, and, for operations conducted under part 121 or part 135 of this chapter, the descent rate will allow touchdown to occur within the touchdown zone of the runway of intended landing;
(2) The pilot determines that the enhanced flight visibility observed by use of a certified enhanced flight vision system is not less than the visibility prescribed in the standard instrument approach procedure being used;
(3) The following visual references for the intended runway are distinctly visible and identifiable to the pilot using the enhanced flight vision system:
(i) The approach light system (if installed); or
(ii) The following visual references in both paragraphs (l)(3)(ii)(A) and (B) of this section:
(A) The runway threshold, identified by at least one of the following:
( 1 ) The beginning of the runway landing surface;
( 2 ) The threshold lights; or
( 3 ) The runway end identifier lights.
(B) The touchdown zone, identified by at least one of the following:
( 1 ) The runway touchdown zone landing surface;
( 2 ) The touchdown zone lights;
( 3 ) The touchdown zone markings; or
( 4 ) The runway lights.
(4) At 100 feet above the touchdown zone elevation of the runway of intended landing and below that altitude, the flight visibility must be sufficient for the following to be distinctly visible and identifiable to the pilot without reliance on the enhanced flight vision system to continue to a landing:
(i) The lights or markings of the threshold; or
(ii) The lights or markings of the touchdown zone;
(5) The pilot(s) is qualified to use an EFVS as follows—
(i) For parts 119 and 125 certificate holders, the applicable training, testing and qualification provisions of parts 121, 125, and 135 of this chapter;
(ii) For foreign persons, in accordance with the requirements of the civil aviation authority of the State of the operator; or
(iii) For persons conducting any other operation, in accordance with the applicable currency and proficiency requirements of part 61 of this chapter;
(6) For parts 119 and 125 certificate holders, and part 129 operations specifications holders, their operations specifications authorize use of EFVS; and
(7) The aircraft is equipped with, and the pilot uses, an enhanced flight vision system, the display of which is suitable for maneuvering the aircraft and has either an FAA type design approval or, for a foreign-registered aircraft, the EFVS complies with all of the EFVS requirements of this chapter.
