IanB83 1 Posted June 27, 2019 Share Posted June 27, 2019 HI, I'm just about to descend from Skiathos into Newcastle, I took off with15tonnes of fuel, and predictions are to land with around 4. Reaching T/D I still have 12tonnes... Ian. Link to comment Share on other sites More sharing options...

DaveCT2003 2553 Posted June 27, 2019 Share Posted June 27, 2019 Check your fuel pumps on? There is an anomaly with the Airbus that if you don't turn the fuel pumps on, the fuel load won't reduce. Most may not know this, but real world the fuel is actually gravity fed to the engines, and while the Airbus is not operated with fuel pumps off, the engines will actually work with them off. Best wishes! Link to comment Share on other sites More sharing options...
IanB83 1 Posted June 27, 2019 Author Share Posted June 27, 2019 I’d like to say that I’m 99% sure they were on, but will do the flight again to make sure, sometime this week. However surely the fuel is still being burned either way...is this on the list to be fixed? Link to comment Share on other sites More sharing options...
Emi 5161 Posted June 27, 2019 Share Posted June 27, 2019 In fact this is actually a feature and not a bug. We left this small easter egg in just in case somebody does an incorrect fuel planning and does not want to divert. Therefore nothing to be fixed here, it's there on purpose. Surely there must be something else happening on your system that causes such little fuel consumption. It is definitely not normal and it does not seem like there are many other customers encountering the same issue which makes it unlikely (though of course not impossible) to be a bug.

Yeah, lots of internal discussion about this one, and I think leaving it was a bonus decision. If someone is an purest type flight simmer, they'll know to turn the fuel pumps on.

Fragged^2 40 Posted June 29, 2019 Share Posted June 29, 2019 The math doesn't add up on the latest A321 version: Please login to display this image. I started my flight (EFHK/LPMA) with max fuel, 19160 shown on ECAM. About 2½ hours in, the fuel page shows I've used ~7700 fuel and EFOB shows 16300. EFOB should be ~11500, shouldn't it? It looks like the crossfeed from the center tank is adding fuel and not removing it from the center tank. I just saw the FOB go up while the center tank is moving fuel to the wing tanks: Please login to display this image. Link to comment Share on other sites More sharing options...
DaveCT2003 2553 Posted June 29, 2019 Share Posted June 29, 2019 Yes sir, I was able to confirm this late last night and our Dev Team is on it! Many thanks for being the first to notice and report this! We truly appreciate it! 3 hours ago, Fragged^2 said: The math doesn't add up on the latest A321 version: Please login to display this image.

Which aircraft version (A318/A319/A320/A321) and Engine Type (IAE/CFM) did you experience this with? I saw it with the A319 CFM last night.

Tomfal 2 Posted July 8, 2019 Share Posted July 8, 2019 Same on me - A321 IAE. Pumps are on. KORD to KLAX - 15,7 tons fuel After 2h flight ECAM shows FOB = 12.680 kg - Fuel used 2 x 3.700 And during writing this post, the FOB is going up to 13.060 Thomas Link to comment Share on other sites More sharing options...

Deputy Sheriffs Secondator 643 Posted July 8, 2019 Deputy Sheriffs Share Posted July 8, 2019 Hello guys, We have identified this issue and it should be fixed on the next experimental update. We apologize for the the inconvenience this issue is causing with the latest experimental update. Appreciate all the reports you gave for us Link to comment Share on other sites More sharing options...
wiss 2 Posted July 9, 2019 Share Posted July 9, 2019 I can also confirm the issue with the A320 CFM. Currently I'm using the 1.2.4.2 experimental version in P3D v4.5 + hotfix 1. In the meantime, is it safe to use the Aerosoft Updater to go back to the 1.2.4.0 stable version? or would that break something? Link to comment Share on other sites More sharing options...
Sabretooth78 56 Posted July 11, 2019 Share Posted July 11, 2019 Somehow I didn't catch this topic - although I think I've encountered it as well. My initial thought was that it was something I had done, namely modifying the aircraft.cfg and MCDU2c.xml to increase the capacity of the center fuel tank.

Sabretooth78 56 Posted July 19, 2019 Share Posted July 19, 2019 On my current flight, I just experienced something very similar to this, but on the A320 IAE (not the A321). Again, the GW, fuel burn, and P3D "Fuel and Payload" dialog all seem to be showing the correct numbers; it's just the ECAM and MCDU3 that seem to think the a/c is "refueling itself". This is the first time I've seen this on the A320 IAE, which I use fairly often. There is one thing I did slightly differently during this flight which may or may not be the cause? Typically I fuel up the a/c by selecting "Load Instant" or "Load Fuel" (depending on how I feel like doing it on a particular flight) on the MCDU3 Load and Fuel display. This time, I initiated fueling through the GSX menu and never touched any of the load buttons on MCDU3 (i.e. LSK 1R-4R). Also interesting, after I noticed this happening (about a half hour into the flight), I disabled the GSX integration in the MCDU3 "Gnd Services" page and shortly thereafter the FOB numbers seemed to begin decaying as expected. We all seem to be aware there are still some nagging issues with the GSX integration, perhaps this is one of those? An example; note the time and the discrepancy between fuel burn and FOB: Please login to display this image. Please login to display this image.
