interim measures from the report
Safety Recommendation 2008-047
It is recommended that the Federal Aviation Administration and the European Aviation Safety Agency, in conjunction with Boeing and Rolls‑Royce, introduce interim measures for the Boeing 777, powered by Trent 800 engines, to reduce the risk of ice formed from water in aviation turbine fuel causing a restriction in the fuel feed system.
it goes onto say...
In addition, an engine response non-normal procedure was added to provide a procedure should the engine fail to respond to a thrust application.
The procedure called for the thrust levers to be set to idle for 30 seconds,
after which each engine thrust lever is moved to max thrust to ensure the restriction has cleared.
oh....
30 seconds....? erm like you have 30 seconds to wait when your are 450' AGL
at 108 kts and both engines no longer have any ooomph in them and the staff car park badges in the windscreens are easy to read hmmmm...
