Fuel Dump Over EWR!

Tue Dec 20, 2005 7:22 am

hey guys, I just wanted to tell all of you that yesterday the 18th, a kallita 747-200 freighter took off around 2:30 or 2:40 pm and i noticed that it was dumping something because of the white stream it was releasing could anyone tell me why that plane would dump fuel within seconds after takeoff.
thanks for your answers!!!

Are you sure it wasn't just condensation off the wings?

There is a situation where excess fuel can be dumped out the fuel dump lines on rotation on a 747, due to the way the fuel system works. I suggest searching Tech/Ops and failing there, posting there.
There are 10 kinds of people in the world; those who understand binary, and those that don't.

The flight (CKS329) continued on to Liege, Belgium (LGG) so dont think it'd be dumping fuel on climbout.

I believe this has been discussed here before that the 747 has an overflow vent on the wings. If there is any fuel collected in the overflow, the combination of airflow across the wing and the rotation angle causes this fuel to spray out looking like fuel dumping. It was discussed that the wing tanks are always filled totally before fuel is stored in the center tank(s), it is not unusual to have some fuel in the wing overflow.
