Fuel Used (FU) doesnt match with Fuel on Board (FOB)

Featured Replies

Hey, I couldn't find something about that so I started a new topic. Please correct me if I am wrong.

I did a flight from ETNW to BGGH. Calculated Block Fuel was 25.7t, Trip Fuel 16.7t. 

Even on my first Fuel check I saw that the Fuel used didn't match with the FOB. The FU was almost exactly as calculated, but the remaining Fuel on Board was far away from that. For example, after around 4 hours I had 16t FU but I still had 22.2t FOB. That doesn't make any sense. 

Was it my fault or is it a system fault? And if its a system fault @iniBuilds Team I would appreciate a fix.

Best regards

Can confirm that i had the same issue. Was flying from EDDK to BIKF

Simbrief gave me block fule of about 20t. I chose to load up 24t of fuel, due to the weather, as I wanted to be able to either hold for longer or divert. 

During cruise, the Fuel used by the engine seemed to be accurate, however once I arrived in BIKF, I still had about 21 tons of FOB

Something is definitely wrong with the Fuel Burn, i'm not sure if it's just a Bug calculating FOB or if i actually had that amount of fuel left, as i forgot to check it against the payload manager

I can confirm to you that the fuel in the payload manager was correct. I only did that flight to check the fuel issue. I double-checked to ensure everything was set up correctly.

 

Thanks for the update, hope this get fixed by Inibuilds, seems to be new with SU4.
