The suggested setup for MFD1 includes the "Window VNAV On". I don't see a mention of that in the FMS primer and was wondering how to turn it on.
Hey Kari,
If you open up one of the CDUs, then click on the "DSPL MENU" softkeys above the letter and number softkeys, then in the bottom right "SIDE L/R" select which MFD you want to manipulate, then on the bottom left "WINDOW OFF/ON/VNAV" you can toggle through these.
