Operating below the minimum descent altitude (MDA) without proper visual references.

ACS element text (the applicant demonstrates understanding of)

Operating below the minimum descent altitude (MDA) without proper visual references.

Bottom line

The dive and drive technique also results in the aircraft maintaining an extended level flightpath as low as 250 feet (ft) above the ground in instrument meteorological conditions (IMC). Approaching the MDA, the pilot has two choices: continue the descent to land with required visual references, or execute a missed approach, not allowing the aircraft to descend below the MDA. Pilots must not descend below the MDA when executing a missed approach from a CDFA.
