It is not correct that VR is higher than VMCA. But perhaps you mean VR is higher than stalling speed VS? VR is higher than VMCG and V2 is higher than VMCA. We don't actually consider VR and VMCA directly as VR is considered part of the ground state and VMCA part of the airborne state. For performance calculations we ensure VR is always higher than VMU (minimum unstick speed) so we can safely lift off the runway without a tail strike and wih sufficient lift when out of ground effect. This aerodynamic performance must be satisfied even if we lose one engine, hence why we continue to accelerate after VR and lift-off until reaching minimum V2. So the sequence is: V2 > VMCA > VR > VMU > V1 > VMCG
so good to see you captain carsten, i hope you're doing well and i'm happy to see these videos from you, such a good instructor and a mentor
Captain I belive VR is 1.05 Vmca ie Vr is always higher than Vmca, Kindly correct me if I am wrong

@@MindSpaceXAviation Thank you for clarifying my confusion captain
N there's GD....
