1.2.7 Fuel Flow increased significantly?

Featured Replies

Hi iniBuilds team,

with v1.2.7 I notice a significant increase in fuel consumption by around 1.1 t per hour. According to the Flightplan provided by Simbrief the AVG FF KGS/HR should be 6221 - it is around 7400 during flight. It used to be pretty spot on before v1.2.7 - now it's impossible to reach the destination airport. Anybody experience the same behaviour? Any ideas or workarounds?

Same here, crash in the ocean before 300nm from destination

Did you guys monitor EFOB at destination during the flight? I just flew for a couple of hours and the EFOB stayed at 5.6--5.7 T during the whole flight (but I ended up at the gate with about 4200 kg. Is that consistent with your observations, that the calculated EFOB @ DEST stays reasonable through the flight but ends up overestimating?

Yes, EFOB at destination stayed pretty much the same all flight. Maybe increased a slightly bit the longer the flight was and the lower the FF got over time.

Hey, I just finished the second flight with 1.2.7 and fuel factor is like 6 %, yes :-)

You can download my simbrief there and crosscheck it with my measured data: LKPR TNCM A350 1.2.7.zip

I made a script which saves my flight data during the flight, maybe it could be helpful to anybody :-)

Hello again,

I've now completed the P06 fuel factor flight here: https://galerie.klusik.cz/presentation=1ec2bc09

As I mentioned before here: https://forum.inibuilds.com/topic/41833-127-fuel-flow-increased-significantly/#findComment-101842

Raw data: TNCM LKPR A350 1.2.7 FUEL FACTOR P06.zip

OFP attached for comparsion. I let ChatGPT to compare the data and attach the PDF as well.

It looks like the P06 is about right, so far. I know it could be changed and probably (my guess) is they (inibuilds) tuned it to SU7 and with SU7.1 patch it just went against itself, but this is must my guess :-) With P06 my divergence off plan is about 0,2 %, which is nice, I guess :-P Planned trip fuel was 53 970 kg and real was 53 866 kg :-)
