Does anyone know what spec Av fuel is uplifted out of Bejing?
The temps enroute were very low with -73 degrees OAT at around 35,000 ft.
Our fuel temp got as low as -43 degrees C but we had Jet A1. Would have been a different story with straight Jet A.
The 777 was relatively lightly loaded and would have climbed to a higher alt and more quickly and cold soaked for longer. Just wondering if the power loss (if indeed there was one) could be related to fuel icing or more probably fuel waxing. Any fuel flow restriction would not be so apparent at low thrust settings, as in the descent, but may have become an issue when power was applied during the later arrival stage. This may have led to a total or partial engine failures.
Pure speculation I know. Just tossing around ideas.
