ACS element text (the applicant demonstrates understanding of)

The procedures used during a powerplant(s) failure on takeoff, the appropriate reference airspeeds, and the specific pilot actions required.

Bottom line

V1 is the maximum speed by which a rejected takeoff still allows a safe stop within the remaining runway or runway and stopway. V1 is also the minimum speed which assures the takeoff can be safely completed within the remaining runway, or runway and clearway, after failure of the most critical engine at the designated speed. To be prepared for emergency situations, memorize the immediate action items and, after completion, refer to the appropriate checklist.
