October 13, 20205 yr Is there a trick to figuring out what the ZFW is and how to input it in the MCDU? If I click on the blank boxes, I get values but when I try to enter the values, I get a Format Error message. I am looking on the fuel page in MSFS and I don't see that as a value and the values I have for simbrief don't seem to translate. Thanks! I am on the latest version of the unstable Mod as an FYI and I downloaded the patch todaay Intel Core i7 12700K (5.0GHz Max Boost Clock) 12-Core CPU 32GB G.Skill Performance DDR4 SDRAM 3600MHz Graphics Processor:12GB Nvidia GeForce RTX 3080 Ti, GDDR6x System 2TB Western Digital, NVMe M.2 Solid State Drive
October 13, 20205 yr If you plan your flight with simbrief it will be in the briefing document it produces. Otherwise, in sim you can set you fuel to zero in the fuel and payload screen and your gross weight will equal your Zero Fuel Weight. As for entering it in the MCDU you normally enter it in thousands of pounds, so for my flight last night it would have been 136.9 since my ZFW was 136,900. I believe standard practice is to round up ZFW, so 131,870 would be 131.9 in the MCDU.

However, no matter what value I enter, it says "format error" Intel Core i7 12700K (5.0GHz Max Boost Clock) 12-Core CPU 32GB G.Skill Performance DDR4 SDRAM 3600MHz Graphics Processor:12GB Nvidia GeForce RTX 3080 Ti, GDDR6x System 2TB Western Digital, NVMe M.2 Solid State Drive
October 13, 20205 yr Author This has to be some sort of bug... I have never gotten this before.

October 13, 20205 yr You have to enter the ZFW and the CG together. For instance in kgs like this 50.2/16.3 Lee Lee H i9 13900KF 64GB Ram 24GB RTX 4090
October 13, 20205 yr Me too, i don't understand too. By example i fly a A320 From KLAX To KSFO: PLANNED FUEL --------------------------------- FUEL ARPT FUEL TIME --------------------------------- TRIP SFO 2509 0053 CONT 15 MIN 703 0015 ALTN SMF 1197 0028 FINRES 1175 0030 --------------------------------- MINIMUM T/OFF FUEL 5584 0207 --------------------------------- EXTRA 0 0000 --------------------------------- T/OFF FUEL 5584 0207 TAXI LAX 200 0020 --------------------------------- BLOCK FUEL LAX 5784 PIC EXTRA ..... TOTAL FUEL ..... REASON FOR PIC EXTRA ............ WEIGHTS ------- EST MAX ACTUAL PAX 177 ...... CARGO 0.0 ...... PAYLOAD 18.5 ...... ZFW 62.2 62.5 ...... FUEL 5.8 6.5 ...... POSS EXTRA 0.7 TOW 67.8 68.5 LDG...... STAB TRIM ...... LAW 65.3 66.0 ...... What's the exact value that i must enter for the fuel in order to have the exact value of ZFW in the FMC?
October 13, 20205 yr By definition the fuel doesn't impact ZFW. ZFW is the weight of everything other than fuel, ie the portion of the total weight that will remain constant during the flight. Note that the default Airbus only supports weights in pounds right now and the weights shown are in KG. If you enter weights in KG into the MCDU that will give you an error message as it assumes you're using pounds and the weights entered would be too low to be real in pounds. Perhaps that is what's generating "format error". On that flightplan Block Fuel is your total fuel, but you enter that elsewhere, it has no relation to ZFW.

October 14, 20205 yr For the A320, you need to enter ZFW in kilograms. To find your ZFW in MSFS, zero out the fuel as mentioned above, Then your takeoff weight is your ZFW. If it is 110,000 lbs for example, then you need to enter 49.9 (followed by a "/" and the ZFW CG. Now, here's the catch, There is a bug in the flybywiresim mod, that you need to enter three digits to the left of the decimal point for ZFW, so for 49.9, you need to enter 049.9. They were working on fixing this, and it may have been fixed by now.
October 14, 20205 yr OK... so I noticed this as well. But the solution? Do not enter anything. Just click twice on the side button next to ZFW/ZFWCG, and it should compute the data for you automatically.
