OK thanx. Thats what I wanted to hear. First of all After takeoff CG vs trim are not in the same relation as before takeoff (takeoff trim setting). Than I think you dint understand me. As described in ISI 00.00.00391 Vapp is calculated by FMS in a way of: 1. A fixed CG of 25% is used before approach and,
2.Current acft CG during approach
Thats why the values of Vapp before/after initiating the approach might be different. And Fly Smart v5.0 gives us opportunity to add the expected CG to performance app during des. preparation and get real Vapp.
