My recent experience looking for good 777 FMC stuff suggests that companies like Honeywell protect info such as FMC manuals in a very zealous way. Can't think why. I understand the need to look after their technology and research/development ..... but the pilots still have to learn to use the darn things properly. There is a culture of 'knowledge is power' and they don't necessarily want the end users to have too much 'power'.
