fuel at shutdown
From a USA 737NG pilot, that sounds about right, perhaps a little to the high side of what I typically see. For a planned dispatch with no alternate fuel, our OPSPEC requirement is 55 minutes of fuel based on the last burn rate at cruise, I'd say around 5000 lbs or 2300 kg is typical. When destination weather requires an alternate plus 45 minutes of fuel based on the burn rate at last cruise, fuel remaining at block would be closer to 2800 kg or 6100 lbs.
