May 22, 20188 yr Hi, I’m just wondering about the message that pops up on EICAS When you have an FMC Scatchpad message? The sim gives the EICAS message “FMC” which always makes me jump as I associate it with the message ‘FMC LEFT,RIGHT” which signifies a potentially troublesome FMC failure. Im not sure if this message is one of the many company specific options but certainly on my aircraft an FMC scratchpad generates the EICAS message “FMC MESSAGE ‘ I Know the message has been “FMC” since the legacy versions, which I was involved in testing and advising on , but I can’t remember if I raised the question at the time so it may well be company specific or if not it’s probably my fault for not raising it 12 years previously ! I have a picture of an EICAS “FMC MESSAGE “ for your enjoyment, but not sure how to attach it to a post. cheers Jon Bunting 787 captain.

May 23, 20188 yr Weird thing for me is, when I flew the plane in FSX, it always said FMC MESSAGE. When I flew it in P3D V4, I only ever saw it read FMC. Captain Kevin Air Kevin 124 heavy, wind calm, runway 4 left, cleared for take-off. Live streams of my flights here.
May 23, 20188 yr Author Thanks Kevin, then perhaps it’s my memory that’s at fault or it’s the FS9 version I’m remembering. The real world version I operate at least,has FMC MESSAGE, just wondering if the “FMC” EICAS may have slipped through if it’s not a company specific option? Jon Bunting 787 captain.

Jon Bunting Funny you mention this because I saw the same "FMC" EICAS message the other day flying the PMDG SQ B777. I agree with you that this message should in fact be careted on the B744 because it is not found in the QRH and read " >FMC MESSAGE ". Bertie G Bertie Goddard
May 24, 20188 yr Author Now that’s interesting, because as you say Bertie you would expect FMC MESSAGE to be careted as there is no QRH action, and indeed it has a caret on John’s photo above. And yet I have a photo here (which I’m not sure how to post)I took the other night on the aircraft of FMC MESSAGE without a caret ! Now, this particular FMC MESSAGE was triggered by a CPDLC comm established scratchpad message.I wonder if there is a difference between internal FMC generated scratchpad messages and ones generated by CPDLC activity? Or perhaps a different software version on the aircraft. Jon Bunting 787 captain. Previously 24 years on 747-400.Technical advisor on PMDG 747 legacy versions QOTS 1 , FS9 and Aerowinx PS1.
May 24, 20188 yr A video from my screen from two months ago, but starting at 5:48:00, you can see it read just FMC. This is P3D V4. Captain Kevin Air Kevin 124 heavy, wind calm, runway 4 left, cleared for take-off. Live streams of my flights here.
May 24, 20188 yr As I recall, a white FMC status is a prompt about data uplinks for the FMC. Amber FMC MESSAGE means there’s a scratchpad warning message that needs attention. Edited May 24, 20188 yr by kevinh

There’s the Amber “FMC LEFT”. “FMC RIGHT” and “FMC MESSAGE” EICAS advisories but no EICAS or memo message which just states “FMC”, to the best of my knowledge. Jon Bunting 787 captain.

May 26, 20188 yr Author Yep, I’ll submit a ticket if that’s the right thing to do. I just thought I’d post here first to make sure it wasn’t correctly modelled on some other variation of software I wasn’t familiar with. This thing has so many variations and options it’s easy to make a fool of your self by pointing a finger at something you’ve personally not seen before. cheers Jon Bunting 787 captain.

May 26, 20188 yr There was a Boeing Service Letter 747-SL-31-092 (8 Nov 2010) which mentioned this: Quote 34: >FMC MESSAGE ... C.... Revised to add caret to make this message applicable to 747-400 IDS systems with new FMC. Do they mean the NG software? And does it apply to those aircraft which don't have new FMCs? Surely they didn't have NG FMCs back in 2010? Edited May 26, 20188 yr by Qavion2 John H Watson (retired 744/767 Avionics engineer)
May 26, 20188 yr Author As of last week my jet, with the original FMCs , was throwing out FMC MESSAGE without a caret ! Maybe they’ve changed their mind again, who knows. Jon Bunting 787 captain.

Jon Bunting No, it's definitely "FMC" in white. Perhaps it's only in the 777?
