ACS element text (the applicant demonstrates understanding of)

The pilot's visual references when performing the maneuver.

Bottom line

No distinction in the pilot’s operation of the flight controls is permitted, regardless of whether outside references or instrument indications are used for the performance of the maneuver. Anytime a VFR pilot is unable to maintain airplane attitude control by reference to the natural horizon, the condition is considered to be IMC regardless of the circumstances or the prevailing weather conditions.
