Re: A350-900 now has a 283t MTOW

I don't think it was a guess. Ops specs and regulations vary from 200 - 220 lbs per pax. Completely accurate, or not, that's how the flight would be planned. In the US FAA new weight and balance standards calculates passengers weights with carryon luggage at 190lbs summer and 195lbs in the winter. ...

There is no tyre speed issue with the A359 in JNB, at the highest weights on an ISA day rotation would be around 162 kts, which is a ground speed of 176 kts, well below the standard tyre speed limits (204 kts ground speed).
