@Gary - bug in Planning portal?

[Aleks]

I was investigating why Simbrief is throwing back all the time "PAYLOAD/CARGO LIMITED BY MZFW".

I captured the API call from your site to Simbrief and I think the culprit might be that you are instructing the Simbrief that weights are in kilograms (Units=KGS), yet API call sends some weights in lb. At least I think that OEW of 373.575 is in lb?
I also see that Boeing gives 361,600 lbs (164,020 kg) for OEW, and 53,985 Gal (204,350 l) as max fuel which should be about 164059 kg of Jet fuel, while API is sending 380 600 litres (not kg) as max fuel. https://www.boeing.com/content/dam/boeing/boeingdotcom/company/about_bca/startup/pdf/freighters/747-400f.pdf

I can see that each API call has different cargo weight, so your site is correctly sending random cargo, but seems kg vs lbs is throwing Simbrief off.

This is for Cargolux 747F.

Attached are two API calls (I removed API key, etc.)

Aleks,

Thanks for the info, just to confirm this issue is only affecting the CARGO variant?  Never seen this on the 744 lite or full size versions.

Cheers

That is correct, Cargo variant (Cargolux).

Thanks for looking into it.
