"V2 + 10, safe height speed, flap 18" , callout is still wrong here, the callout is corresponding to the speed of Flaps 18 configuration, not 24 or 30. For example today i was configured with flaps 24 (V2 128). The corresponding callout had to come at 138kts. But no, it was coming at 148, wich was the V2+10 for the Flaps 18 configuration (V2 138).
I have this issue from the begginning.
