The extra burn was on average around 1 lb/minute, the profile flown was not as planned. Over 14+ hours it adds up.

According to the United internal communication over the event, they only took the full fuel required under their OpsSpec.

Folks,
I was at EGLL one morning, when one Concorde couldn't even make the stand, it has to be towed in --- that is really cutting it fine.

Please all remember that the 30m FFR is to ensure all engines are running at touchdown, given the vagaries of fuel contents and consumption order of accuracy -- an engineering fact of life --- 30 minutes holding, calculated or indicated, could be zero minutes in fact.

There are bleeding good reasons for establishing the ICAO SARP --- in the accident and serious incident history.
Tootle pip!!

Can you please spellout chapter and verse what their OpsSpec says they should have carried.

are you serious: 1lb per minute. That’s 27 kg per hour which is less than 400kg over the whole sector and you are calling that out as mismanagement.
The stupid STARS and vectors that have to be flown at SYD use more than that.
