If I'm correct, there is effectively already a 250kt speed restriction 12 before LAM, so I don't see a sufficient speed excess potential that could prevent any additional thrust requirement somewhere in that hold ... but not a word from AAIB !?

“both of the eng spar valves were found to be open, allowing the fuel leak evident at the accident site” they avoided to mention how much fuel they drained from the main tanks.
I don’t know which rate a spar valve leaks but it must be measurable and an estimated leaked fuel amount must have been determined … but not a word from AAIB !?
BA pilots kind enough to answer
For a typical PEK-LHR T7 flight plan:
- What is the planned fuel allowance for taxi ?
- Is it correct to say that planned arrival fuel is departing fuel minus (planned taxi fuel + planned en route flight fuel) ?
- Which quantity or en route percentage is allowed to reserve fuel ?
- What does include the planned arrival fuel at LHR (in this case 6900kg) ?
AAIB … it doesn’t hurt asking
What was the planned en route time ?
What were the planned and actual ZFW ?
