What will the new NGC FMC bring ?
« on: Wed, 5 Dec 2018 06:50 »
Now that I learned that HH is working in that new FMC, I would like to get, in a nutshell, an idea about what it will bring to the PSX 744 fleet ?

Really looking fwd into it, but more because it's a "new toy" more than because I understand wjhat it really is about :-)

Help me understanding :-)

It has more memory for the nav and route database. That's its main selling point...

And possibly also the NG-FMC capability to fly RF legs ...



... thus using all these fancy curved RNP approaches into tiny little mountain airfields (next Worldflight maybe RNP approaches only?  ;D )

Hmmm,

than it's mostly about memory and curves :-)

Looks promissing :-))

Here is some more ... (but I don't know if all of that is in the NG-retrofit for the -400)

Thank you all !

Looks interesting, to say the least, but the cherry in the top of the cake is even more tasty :-)

Thanks Markus for sharing the link!

I was wondering how much difference is there between old and new version of display message for Flight Controls and Hydraulics.

Sounds like NGC FMC will be a useful add-on (for all those new approaches). I still have to master old gen FMC though. Nonetheless, thank you Hardy for continuous improvements of the PSX. :)

Cheers,
Andrej

That's the EICAS, not the FMC. The EICAS won't change with the new FMC.

Another one of several options: The CDU displays may be changed to the multicolor LCD version. None of the real 744 aircraft have multicolor currently, but they may replace them in the future, like they did with the LCD MCPs in the past decade. The new FMC software itself is able to generate multicolor, it's just the old CDU that keeps the text in green.

Looking forward to this update!

And I hate to always be asking for more, but any chance some kind soul would write an app for iPad to control the upgraded CDU? Or update the current one, if at all possible. I assume it won't work "out-of-the-box" with the current iPad app?

Hi Ahaka!

I guess current "PSX Remote" iPad app will run without requiring any update, as it "simply" sends to PSX' MCDU the page keypresses, LSK presses and keystrokes on CDU alphanumerical keyboard, then reads screen state to display it on the iPad.

Hi Pierre,

So it can read the font color etc. from PSX to display it correctly? I guess it will work then, assuming all the buttons remain the same.

Well, the background graphic could be updated to depict the LCD version, of course. ;)

Add-ons that generate their green text screen on their own don't know what colors are to displayed. There will be additional network variables for the text color management.

Add-ons that use the PSX graphics on their hardware screens will get multicolor as shown on PSX, unless their screens are monochromatic.

This multicolor stuff is the least important option. As I wrote above, there is no multicolor CDU on any real 744 yet.

So let’s make history and have it in PSX first. :)

Well, of course the inner workings of the FMC is more important than the visual style of a CDU, but it’s intriguing me to have a modern CDU in a 744. At a glance it will look like a 748 flight deck.

Dear Hardy,

thanks for your response. I may have been misunderstood.
My question was rather a general inquiry rather then expectation of an update of EICAS with the NG FMC update. :)

Thanks nonetheless!
Cheers,
Andrej

Shut up and take my money!!!  ;D

Would love to fly SCEL RNP-AR procedures, already in the navdata, but not really usable, as the current FMC doesn't really follow the RF legs



Even better would be to fly SCBA RNP procedures, but they're not currently available in the navdata, I guess it makes sense as no 747 or any CAT D aircraft flies into SCBA, only A320s, which routinely fly these cool approaches.



And possibly also the NG-FMC capability to fly RF legs ...



... thus using all these fancy curved RNP approaches into tiny little mountain airfields (next Worldflight maybe RNP approaches only?  ;D )

About these "alternative" procedures that we will be able to vly with the NG FMC, I was wondering what happens when a 744 has to operate into such an airfield ? 

- Other available precision / non-precision procedures are used instead ?

- If possible a visual approach must be used ?

Exactly - same as any other aircraft (or operator) that does not have the "A" that is "R'd" for RNP AR procedures  ;)

You would have to use one of the "traditional" approaches available, almost certainly with higher minima (which is one of the main reasons for RNP AR - there are very few commercial airports in the world where there is no possibility of any form of instrument approach at all - but RNP AR procedures may allow for much lower minima than would otherwise be possible within the confines of the requirements for obstacle clearance on something like a VOR or NDB approach and therefore provides a greater chance of getting in when the weather is poor).
