Does anybody have the 777 Honeywell FMS supplementary data document that they would feel comfortable with sending me? I've been getting pretty deep into the weeds lately, and the FMS users guide, and other pilot-faced documents have really not been cutting it. I'd love to get my hands on this and figure out how some of the more nuanced functions actually work.
I don’t have the supplementary documents but have been flying the 777 with the Honeywell FMS for some time and our FCOM (I don’t think much changed if at all from standard) has enough information in it to be able to use/understand all the functions of the FMC without further guidance, in that you could dive deeper but it’s not going to affect the operation.

There is quite a flock/gaggle of 777 pilots on PPRuNe and posting some examples here on the Tech Log might get some explanations? I certainly don’t know everything but would be happy to help with what I do understand...
