ACS element text (the applicant demonstrates understanding of)

Accomplish the non-precision instrument approaches selected by the evaluator.

Bottom line

RNAV approaches without approved vertical guidance and conventional NPAs should be flown, whenever possible, using a CDFA technique. A CDFA starts from an altitude/height at or above the FAF and proceeds to an altitude/height approximately 50 ft (15 meters) above the landing runway threshold or to a point where the type of aircraft will begin the flare maneuver.
