An appropriate takeoff rotation maneuver is a balance between good takeoff performance and sufficient margin versus tail strike, stall speed, and minimum control speeds.
Applying the 3°/s rotation rate requested in the SOPs is the key to ensure that the aircraft meets the expected takeoff performance. Flight data monitoring shows that the rotation rate values in service vary and a lower rotation rate is observed in some cases with the associated degradation of takeoff performance. This article describes both the takeoff rotation laws available on Airbus Fly-by-Wire (FBW) aircraft and the recommended rotation techniques that will enable flight crew to achieve consistent takeoff rotations at the requested rotation rate.
