Exceeding MZFW With Nowhere Near Full Load

[KORDATC 80]

I've been playing around with the EFB and I've been exceeding the Maximum ZFW with 0 cargo, and nowhere near a full load of passengers.  I'm just looking for some verification that I'm not nuts before submitting a support ticket, as I'm probably doing something wrong.

And, sorry, just realize I put this in the wrong forum...

Alright, so now I just verified it with the FMC payload page and something is not right.  For example, the maximum capacity of pax in the FMC is 467.  The maximum capacity of pax in the EFB is also 467.  However, when using the "Read From ACFT" prompt on the EFB, it loads a lot less passengers than the FMC shows, yet with weights as if it loaded a full load.  Yet, it does load cargo weights correctly.  See the attached images for comparison between FMC and EFB after pressing "READ FROM ACFT".

You'd be better off submitting a support ticket for this. I did also discover that the fuel loading is a bit off, but I need to investigate some more before I submit a support ticket for that.

I just submitted a support ticket.  After reviewing it, it is without a doubt a bug.  What appears to be happening is the FMC and EFB both have different average passenger weights.  It's almost as if the weight of a passenger in the EFB is more than double that of one entered into the FMS.  So basically, on the EFB you can't even have more than half a plane-full of people before exceeding the MZFW.

Edit: And honestly, I haven't even checked the fuel loading portion of this.

I'd say it is possibly related, yes.  His, *I believe* was referring to the MTOW.  I haven't gotten that far yet to test that, but mine is more of an issue with the displayed ZFW vs. MZFW.  Seems like the EFB thinks each passenger weights 350+ pounds vs. the 195 from the FMC.

So, if I hit "READ FROM ACFT", I will get the correct ZFW in the EFB, but there will be less than half a load of passengers.  So, from a weight aspect, I'm fine.  However, the loading does affect the CG.

Robert Schumacher.

I have the same issue. So now we don't know if the CG is correct. If I am thinking this correctly.

Alright, so just heard back from Chris Makris on the support ticket.  It is indeed a bug.  It will be fixed!  Great (and quick) customer service as usual!
