The First One. It’s « Alt Blue » not « FL300 blue ». NightStop and GetTheQrh, You can not omit the « ALT » call out! This is a really important FMA call and I would be surprised if your SOP says otherwise. For example: If you are at FL 200. And you are clear to descend to FL 140 and you accidently use VS+1500’. The « ALT » blue won’t be displayed! The missing « ALT » Blue will be a fast trigger that’s something is wrong. By FCOM, any change in the FMA must be called and with his color when applicable (Blue/Magenta). So skipping it would be a violation of Airbus SOP.
