Hey all, I have a simple question but I didn't find the answer anywere. During cruise while preparing for an ILS approach, in the INIT REF page of the FMC, what is the function of the line: G/S: ON/OFF in the left low corner of the FMC? Thank you!

Hey! I have a slight issue with the autoland system: I've tried a couple of times to perform an autoland on a CAT III ILS, sometimes it seems to work, sometimes it doesn't. I set the ILS frequency on both receivers, match the course left and right and I have the correct ID on the PFD. I arm the approach mode, the LOC is captured followed by the GS. the I have now "SINGLE CH" on the PFD. Here is the problem: when i try to engage CMD B (CMD A is already on) to perform the autoland, CMD B engages correctly but the CMD A goes dark, and I have only one AP engaged, same the other way around. What am I doing wrong?
