The 744 (RR) AMM gives a nice, detailed dive into the EEC in 73-21 but, yes, the GE AMM is much less descriptive.

After the IRS, the ECU/EEC is my favorite system. Fascinating technology and redundancy, in my opinion.

The 767 AMM absolutely does provide info on the FADEC in that chapter, but the 747-400 AMM only explains what EEC means, but no schematics etc.

ASCTU744,

It is chapter 73 (73-21).

I'd say that 48 hrs would be sufficient, the US has 800 bases overseas (so not counting the ones on US territory).

Hangar 7 / ATA Chapter EEC/FADEC

Hi, does anyone know which ATA chapter discusses the EEC/FADEC, I assumed it was 73 but it's not.

Hi Mike,

The problem is solely within X-Plane12 and it affects ALL aircraft, even the Cessna 172. When, however, I remove the PSXView folder out of the 'Plugins' folder I get control back.

You might benefit from a great little program called xOrganizer. This tool lets you disable plugins, scenery and whatnot. I have been using it a lot in my XP11 days, mainly to enable/disable the LiveTraffic plugin or other stuff.

If you want to make it as easy as possible to switch between plugins etc, this is the progam for you. The author is very responsive and considers any good suggestions. It would be a good investment IMHO.

Sounds great Hoppie! It's very nice to see the progress you and Jamie are making with this unit. I got mine to work on macOS earlier this week and it's SUCH an upgrade from the iPad RemoteCDU app, which already was a giant upgrade from 'mousing around' on the desktop.

Fun times! Looking forward to any and all iterations

Having loads of fun with over-engineering this thing, assisted by Claude to keep the documentation up and to do the boring work.

My goal is to get the thing to be useful as a real MCDU, connected to a real piece of avionics feeding it 429 (ARINC 739A). I'm about 99% there, the limitation is mostly that the avionics I have are not FMCs so they don't play with annunciators et al.

Yesterday at sunset I tuned in the ambient light sensors. I followed what I read here and aimed for a trim setting (the -BRT+ scale) of centered for auto-brightness all the way, from pitch black dark room to bright sunshine. And then the trim can do -11 to +11 for adjustments, with -11 == min brightness (tech level 1; 0 is really off, nothing visible, it's an LCD after all) and +11 == max brightness (255) and in between auto gets blended in. This works nicely.

I added a steep gamma correction because at near-dark of course a small step is much better visible than in the sun.

And I balanced out the keyboard backlight against the display backlight. Above a given ambient level there is no need any more for keyboard light.

I would probably not have gone this deep without the Claude (co-work) assistant. It makes dull things feasible.

Its report:

Two ambient sensors (0–4095) are averaged and smoothed, then a perceptual curve maps that light level to an auto brt (1–24). The BRT rocker sets a persistent trim T (−11...0...+12). These blend into the effective BRT: at T=0 the auto value owns the display; pushing T toward −11 or +12 overrides it down to BRT 1 or up to 24 regardless of light. That BRT then maps through a second perceptual curve to an actual backlight level (1–255). The display backlight uses that level fully; the keyboard backlight follows the same curve but switches off above BRT 7, since a bright display needs no key lighting.

Also I had it rescale the fonts that came with the original implementation (the encrypted stuff) and merge in a few Aerowinx font glyphs and move the raster around and made it much nicer.

I will put this code out "soon," there is so much to pick up for others.

As a side effect, this thing obviously will also be kicked to become a PSX MCDU. Not to compete :-) but just because it's so simple now.

I would not worry too much about it, unless they start encrypting/encoding all data, chances are it "just works". I might need to give the update-frequency a little boost, but other than that I don't expect too much of a difference.

Thanks Jamie. Good to hear.

Jamie, that looks fantastic. Bookmarked.
