May I ask a couple of questions on the 777 incident?
What was the temp on the ground while the aircraft was on turn around in China?
What temp had it been exposed to, and for how long, while en route to China?
I understand that fuel "waxing" might be an issue. Fuel does not fully dewax for some time after landing. If an aircraft flies a long haul, sits on the ground in low temps and then flies long haul again the fuel wax status may be enough to prevent required fuel flow as deposits clog filters..?
Would it be desirable to alternate an aircraft between hot and cold destinations to help reduce the possibilty of waxed fuel build up?
Just thoughts..??
