FMC: Fuel Prediction, ETA and ETO incorrect

[Stimue]

Hello, 

first of all: Congrats to this outstanding aircraft ! 

Just a short question. On the FMC progress page, the Destination ETA is highly inaccurate, especially during the first stages of flight.

On a short 60-Minute-trip, I get an ETA for lets say 10 or 12 hours later. The longer the flight takes, the more accurate the ETA gets.

Same with the ETO for the next waypoint. Flight times are much too long here.

And the predicted fuel on arrival is more than actually is in the tanks.

Is this a known bug and part of the WIP on the FMC, or am i probably doing a mistake during FMC setup ?

 

Thanks for help, 

Andreas

Hi Andreas,

That part of the FMS (like the VNAV) is still mostly "WIP" and the values can be considered a placeholder only for future improvement.

We are working on making that work right!

Cheers, Jan
