ALTV will be the armed vertical mode during the descent if the altitude preselect is set to a lower altitude
than the VNAV reference altitude. This indicates the autopilot / flight director will capture the VNAV altitude
reference. ALTS will be the armed mode during the descent if the altitude preselect is set at or above the
VNAV reference altitude, indicating that the autopilot / flight director will capture the altitude preselect
altitude reference.
