Fuel Flow

[borisdjartov]

Hallo i have a question regarding the fuel flow. When i set up a flight plan and analyze the fuel flow i encounter some peculiar results. I am using the openAPI model and when i log the fuel flow every second there are some values which are negative. Additionally, is the fuel flow calculated for 1 engine or is it the fuel flow for the whole airplane?

I can see form the altitude that the plane landed. But i do not understand why this happens so soon. The flight is from Berlin to Frankfurt and with an A320 it should last about an hour, but it is over in half the time. I used the simulation function with fast forward like on the jupyter notebook provided. Are the timesteps not in seconds? I also tried to fiddle with the simulation speed multiplier but i am unsure how or if it even works. I assume bigger values are better and when i set it to 100, 000 it takes ages.

My code and flight plan:

Thank you for your time!
