An unstable approach, including excessive descent rates.

ACS element text (the applicant demonstrates understanding of)

An unstable approach, including excessive descent rates.

Bottom line

Any speed deviation on final approach should be detected immediately and corrected. If an increasing sink rate is detected, it should be countered by increasing the AOA and simultaneously increasing thrust to counter the extra drag.
