Fueltanks in the Airbus A320

Hello @all,

since a few days i am testing the Airbus A319/320 Addon by Aerosoft. Everything works fine so far but i got some fueling issues with the right MDCU (Load/Fuel). If I set a Blockfuel manually or load a Loadsheet and fuel the aircraft, there is always a few amount of fuel in the surge/vent tanks and if I set Fuel=0 on the right MCDU there is always a few amount restfuel in the surge/vent tanks (wing tanks and center tanks are empty). Maybe i got it wrong but i thought the surge/vent tanks should be empty, at least at the startup, in case the fuel expands. My problem here is: i cant use the fuel in the s/v tanks. so a certain amount of the calculated fuel is missing for my trip. Well if I have a final reserve in the tanks it shouldnt be a problem, but if I go for the ALTN Airport, getting set in a Holding and maybe do a MAP I will get some trouble if I cant use the 1000kg fuel filling in the s/v tanks. unsure.png

So my question is: is the refueling of the s/v tanks at the startup just a bug or did i get anything wrong here? Is there a option to empty the s/v tanks (Fuel=0 on the right MCDU just dumps the wing and center tanks but there is still something left in the s/v tanks)?

Hopefully someone can help me! Thank you in anticipation for all the replies ! smile.png


Greetings mrniggo



BTW: the small outer tanks at the ECAM (without any Fuelpumps and without any connection to the wingtanks) are the surge/vent tanks, arent they?

Hi,

no, the ECAM page displays the main tank, the inner and outer wing tank, but the outer wing tank is seemingly not simulated and contains permantently 690 kg fuel.

Hi Frank,

thanks for your reply. ok so, is there any possibility to disable the outer wing tanks or dump the fuel but editing a config file or something like that?

The outer tanks will automatically open their valves if the total FOB drops below a certain amount. It always worked with my setup so what is the problem here? You want to fly with zero fuel? Or do you want to fly with less than 1500kg remaining?

I did a flight this morning, 10nm before landing the engines failed because center fueltanks were empty (well they were never filled up for this short flight, EDDM->EDDS), inner wingtanks were empty but there was still 460kg left in both outer wingtanks. So i guess it was a "less than 1500kg remaining" flight. Why 1500kg? I guess the transfer valves didnt open?

(The flight was a testflight without any reserves to calibrate Fuelsettings for EFASS)

well a few days ago I bought the Airbus Bundle - Aerosoft - Airbus A318/A319 + Airbus A320/A321. Guess its the latest title?

Ok guys just tested some different FOBs in the right MCDU and if the inner wingtank fuel is 750kg each side the transfer valve opens and i got fuel from the outer wingtanks. I have no idea why it didnt work this morning :/ maybe just a bug. Anyway no its working and I got it how the Refueling actually works.

Thanks for your help! :)

@Patrick1246: yes now its working with my Airbus too. no idea what was going on this morning. the transfer valves didnt open :/

ok if anyone got the same problem at anytime i just figured out what the problem was. when i start a flight, fsx is loading my saved standard flight like normal. in this configuration i have 460kg in both outer wingtanks (which shouldnt be possible because of the fill first the inner wingtanks with 750kg regulation). The flight this morning (without any reserves) were just 910kg FOB. In Aerosoft Airbus normally the inner wing tanks were filled until 750kg, after that the outer wing tanks are filled full (maximum of 690kg) and after that the filling of the inner wing tanks is continued. However in my case i just got an FOB of 910kg so below 1500kg, that means the refueling at the gate only fills 455kg in the inner wingtanks and does not work with the outer wing tanks. so if i filled the 910kg FOB in the aircraft i got this --> (460|455|0|455|460) (460kg in the outer tanks because of my saved standard configuration, 455kg in the innertanks is my FOB i put in the right MCDU) now my ECAMs displays FOB of 1830kg but if the outer wingtanks never were filled during the refueling process in the present flight, Aerosoft Airbus didnt recognize the fuel amount of the outer wings and thus will never open the transfer valves. Well in the end i just changed my standard FSX flight with a fuel setting at the beginning FOB 0.0kg like this --> (0|0|0|0|). (outer wingtank|inner wingtank|central tank|inner wingtank|outer wingtank)

btw: sorry for multiple posting this topic, wasnt sure if all threads were still active! :/

Hi,

another reason why using FSX the Airbus should not be part of the "saved standard flight" - we still recommend that FSX should be started with one of its standard planes and only after FSX has been fully loaded the plane should be changed to any other addon plane (like the Aerosoft Airbus).

Regards,

Rolf
