Andre Blossfeld 7 Posted December 17, 2019 Share Posted December 17, 2019 Hi, I did some short flights with the A330 and noticed, that the calculation of EFOB was´nt correct on all flights. In all cases the fuel consumption was nearly the calculated flightplanfuel, but the MCDU showed weird figures. An example from Stockholm to Copenhagen (approx. 1h flighttime): - I loaded 16.5t blockfuel, on ground the MCDU calculated an EFOB of 5.8t (instead of expected approx 10t). - During the flight the EFOB increased up to 7.9t short before landing, what is 2t behind the schedule - as you can see at the screenshot 153nm away from the destination (35nm before T/D) 12.1t fuel on board, 6.5 EFOB. More than 5t fuelburn during descent is defintily wrong calculated. - finaly I landed with 11.5t remaining fuel - the MCDU showed 7.9t EFOB anyway. Rgds Andre Please login to display this image.

Deputy Sheriffs masterhawk 799 Posted December 17, 2019 Deputy Sheriffs Share Posted December 17, 2019 Can you please enable ECAM log? And then upload the syslog file? (Data folder) There are all relevant values stored and we can use it to adjust the predictions. Link to comment Share on other sites More sharing options...
