Unsafe Condition
Under certain conditions during an FMS profile (PROF) descent, the FMS will allow an airplane to descend below the selected flight control panel (FCP) altitude or FMS-constrained altitude, and may not command the autopilot or flight director to level off at the next altitude constraint, potentially resulting in an uncommanded descent below the selected level-off altitude.
