Now I see that's where the 748 FCOM and QRH are. I always use the Ops Center links for that. I had no reason to open the folder where all the 744 manuals are. By text search I found one reference in the section about Rain Maker, again nothing to say where it is. There is no mention of the 748 FCOM in the section about systems.
The Introduction Manual does mention the EFB manual, but I only found where it was from this the forum. It's great that the manuals are provided but it isn't at all clear where the 748 documentation is, or what is available. Sounds like it will provide all the answers I need.
My original question about 748 systems description must have sounded very odd to you as an FCOM was already provided, I just I wasn’t aware of it. I’m sorry Chris, it’s now clear we’ve been talking at cross purposes. I took your reference to it being difficult to have such documentation as being about providing a 748 FCOM. As Marc werote there is an FCOM and QRH inside the document folder.
