Hangar 7 / Re: PSX Updates Pace
Last post by ASCTU744 - Fri, 10 Jul 2026 21:50We used to have lots of updates, but I'm convinced that depended entirely on some forum users geting really specific or testing scenario's that were outside the realm of any conventional normal or non-normal scenario. Hardy knows exactly what I'm talking about 
P.S. But also because PSX got the fundamentals right, PMDG seems to have been much more focused on the surface level stuff which may made development cheap and easy but was destined to result in a lot of problems down the road. I'd even go as far and say that Aerowinx may even be an emulator at this point.

Hangar 7 / Simfest and Aerowinx Forum Sum...
Last post by Gary Oliver - Fri, 10 Jul 2026 21:27Hi all,
The Simfest team are having a real life summer party at www.744experience.co.uk in Cheshire UK on Saturday August 22nd.
This is a free in person event hanging out at the 744 experience with a social, drinks and a BBQ for like minded PSXists and friends at an Ex BA 744.
If you are interested in attending please reply to this post and we will provide details.
Would be amazing to have as many of you from the forum join to talk all things 747 and PSX.
Cheers
Gary

Accessories / Re: FiFLi add-on - First offic...
Last post by vito - Fri, 10 Jul 2026 21:19I have some news !
FifLi has new features: live traffic updated and added spoofing / jamming !
here is extract from readme.txt :
Beta 0.78
- added live ADS-B traffic injection into PSX Navigation Display ! FiFLi will fetch live air traffic from adsb.lol and display up to 7 surrounding aircraft on your ND. Traffic is filtered by altitude (±7000 ft band around your current altitude gets priority). Traffic positions, speeds and tracks are updated in real time. You need an internet connection for this feature to work. You will se, sky is really crowded :-)
Beta 0.79
- complete replacement of wav file based voice system with macOS text-to-speech engine (TTS) ! FiFLi now uses macOS "say" command with Daniel voice (British male, First Officer) and Karen voice (Australian female, Flight Attendant). This means FO and FA announcements are no longer limited to pre-recorded files — speech is generated in real time with natural pauses, emphasis and pacing. Windows users: SAPI is used for speech on Windows.
- FO_speech.txt file now contains all FO and FA announcements which you can read and if you wish modify to your liking :-)
Beta 0.80
- added FO flight controls check ! After engines are started and takeoff flaps are set, First Officer will call for flight controls check. He will smoothly deflect elevator, ailerons and rudder through full range and back to neutral, one axis at a time. You will see the controls moving on screen.
- added cabin temperature monitoring ! If cabin temperature exceeds 25°C during cruise, Flight Attendant will announce it to the Captain. Warning will repeat maximum twice per flight with at least 5 minutes between warnings.
Beta 0.81
- added Taxi Map window ! You can open it from the main FiFLi window. The map centers on the aircraft position and rotates so your heading always points upward. Available controls in the Taxi Map toolbar:
Zoom ( - / + buttons or mouse wheel ): zoom level 1 to 19, remembered between sessions.
OpenStreetMap / Satellite: switch between street map and satellite imagery, remembered between sessions.
FPlan: show your active FMC flight plan route on the map, read live from PSX.
OpenAIP: airspace and airport overlay from openaip.net — requires a free API key from openaip.net, paste it in the "API key" field and press Enter, key is saved for future sessions (I think it is worth !).
Live traffic ( checkbox in main FiFLi window ): shows surrounding ADS-B traffic on the map, see Beta 0.78 for details.
Spoofing/jamming ( checkbox in main FiFLi window ): shows GPS jamming and spoofing zones on the map as hexagons, radiuses of the zones are not shown on purpose :-) .
- added GPS jamming and spoofing overlay on Taxi Map ! When you select the "Spoofing/jamming" checkbox, FiFLi will download daily GPS interference data from gpsjam.org and display affected zones as red hexagons on the Taxi Map. Named regions (Baltic, Black Sea, Eastern Mediterranean, Egypt/Sinai, Syria/Lebanon, Iraq/Iran, Persian Gulf, Central Asia, Russia/Barents) are shown as larger hexagons with a label; other zones appear as smaller unlabeled hexagons. Data source: gpsjam.org — daily crowdsourced GPS quality data derived from ADS-B receiver reports worldwide. You need an internet connection for this feature to work. Data is from the previous day(s) so treat it as situational awareness, not real-time.
Beta 0.82
- added First Officer GPS jamming reaction - this is really interesting ! When FiFLi detects that your aircraft is flying through a GPS jamming or spoofing zone (as shown on the Taxi Map overlay), First Officer will:
- announce GPS jamming detection to the Captain,
- navigate the Captain's CDU to the POS REF page so you can cross-check your FMC position against IRS,
- ask if GPS should be disabled.
When you leave the affected area, FO will announce that GPS appears to have recovered.
Beta 0.83
- improved: the "Spoofing/jamming" zone name label in the FiFLi window now clears back to "--" once you have flown more than 50nm past the edge of the nearest zone.
Beta 0.84
- redesigned GPS jamming/spoofing overlay on Taxi Map: zones are now displayed as red hexagons instead of circles.
Named regions (Baltic, Black Sea, Eastern Med, Egypt/Sinai, Syria/Lebanon, Iraq/Iran, Persian Gulf, Central Asia, Russia/Barents) appear as larger hexagons with a region name label. Other affected zones are shown as smaller unlabeled hexagons.
- zone marker size is now proportional to average GPS interference intensity in that area — a heavily jammed zone appears larger than a marginally affected one.
- city dots on Taxi Map increased in size for better visibility at all zoom levels.
- removed zone boundary circles and crosshair overlay — map is now cleaner.
Beta 0.85
- added automatic fallback for live ADS-B traffic: if adsb.lol is unreachable or returns an error, FiFLi now retries the same query against adsb.fi before giving up. Both are free, community-run data feeds, so this only helps when one of them is having an outage — you don't need to configure anything, thanks to both you can enjoy traffic jam in the sky :-).
-- end
you can get Fifli:

Last post by Jeroen Hoppenbrouwers - Fri, 10 Jul 2026 19:44Moved the stuff from a PC to a RasPi4 -- just works. This Pi actually fits under the panel. Not bad for an extra EUR 80 or so.

Hangar 7 / Re: ATA Chapter EEC/FADEC
Last post by ASCTU744 - Fri, 10 Jul 2026 18:58Ah I see, the PW4000 ones also had way more data. Yeah the EEC makes things infinitely easier for pilots 
no more assym. throttle settings lol
P.S. Please contact me at boeing550@gmail.com, I'd like to ask you something that can't be discussed on this forum.

Hangar 7 / Re: ATA Chapter EEC/FADEC
Last post by Mariano - Fri, 10 Jul 2026 15:46The 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.

Last post by ASCTU744 - Fri, 10 Jul 2026 13:42The 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.

Last post by ASCTU744 - Fri, 10 Jul 2026 12:46I'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
Last post by ASCTU744 - Fri, 10 Jul 2026 12:42Hi, does anyone know which ATA chapter discusses the EEC/FADEC, I assumed it was 73 but it's not.
