Which statement best describes the importance of Vr in takeoff procedures?

The selected answer highlights the critical role of Vr, which stands for "Rotate Speed,” during the takeoff phase of flight. Vr is the speed at which the pilot should begin to lift the nose of the aircraft off the runway, ensuring that the aircraft is capable of achieving the necessary climb gradient to reach V2, or the takeoff safety speed, shortly after becoming airborne.

Maintaining Vr during takeoff is vital because it provides a margin of safety for successful climb-out conditions considering potential engine failure or abnormal situations. By reaching this speed before lifting off, the aircraft is positioned to meet required performance parameters and gain altitude effectively, thereby ensuring a safe ascent.

Other statements may touch on various speeds relevant to flight operations but do not accurately reflect Vr's specific function in relation to takeoff safety and performance.
