What speed must be achieved to rotate the aircraft in a split marker scenario?

In a split marker scenario, the correct speed to achieve in order to rotate the aircraft is Vrot, also known as the rotation speed. This is the specific airspeed at which the pilot initiates the rotation of the aircraft to take off. It's determined during the aircraft performance calculations and is critical for ensuring that the aircraft is positioned appropriately for lift-off, factoring in weight, configuration, and environmental conditions.

Vrot is typically a key component of the takeoff performance criteria, as it ensures that there is sufficient lift generated by the wings when the pilot pulls back on the control yoke or stick, transitioning from ground operations to airborne flight. This speed marks the threshold at which the pilot can confidently lift the nose of the aircraft off the runway to initiate a successful takeoff.

In contrast, V1 is the decision speed during the takeoff roll, beyond which the pilot must continue the takeoff even in the event of an engine failure. Vr, or rotation speed, represents the speed at which the aircraft should ideally leave the ground, but Vrot is often specified in particular scenarios to account for operational considerations. CFL, or critical field length, refers to the required distance needed to safely take off and is not directly related to the speed for initiating rotation
