Hello, I would like to report an issue regarding the flight planning data. When I load and generate a flight directly through SimBrief, the calculated values are significantly different from the values I get when I load the same flight through our Virtual Airline system, even though our system is connected to SimBrief and uses the same airframe/profile.

There are noticeable differences in several figures, including fuel, weights, and other flight planning data. I would expect the results to be much closer, or ideally identical, since both flights are based on the same SimBrief airframe and profile.

Could you please check why there is such a large difference between the flight plan generated directly in SimBrief and the one generated through the Virtual Airline system? It seems that some of the SimBrief profile data may not be transferred or calculated correctly.

Hi, the payload difference is because you are sending manual passenger and baggage weights when generating through your Virtual Airline system (i.e. you are sending acdata={'paxwgt':165, 'bagwgt': 33}). This overrides the airframe’s weights, which are around 176 and 33.

When generating directly on SimBrief, you are falling back to the airframe defaults, which results in a different payload.

You are also sending different values for the Contingency Fuel (Auto versus 5%/5 min) and Reserve Fuel (30 min versus 40 min), which explains the different block fuels.

Best regards,
