Fuel dump/jettison in stormy area
Hi everybody,
I'm looking about restrictions for fuel jettisson (in flight) in stormy weather conditions. Can't see anything in 777 FCOM, I don't remember on A330. Do your compagny or your aircraft's manuel mention any kind of restriction or recommandation about this particulary situation?

This is a cut and paste from the OMA of a now defunct airline:
"The jettison operation should not be conducted below 6 000 ft above ground.
Fuel jettison in a holding pattern and descent within the area previously used for jettison should be avoided in order to remain outside the kerosene cloud.
Fuel jettison should not be performed in the vicinity of thunderstorm activity."

Boeing information, as I recall it, is that at normal speeds for fuel jettison the flame front burns slower than the aircraft is moving so it will always drift backwards and never catch up with the aircraft.

Depends on the type. The 600 series models with tail tanks are able to dump the tail if the transfer system fails or is inhibited folloewing a rotor burst to prevent the c of g going too far aft as you burn off the rest of the fuel.
There was a flying boat back before WWII that exploded and crashed while dumping fuel.
Granted, that was gasoline, not jet fuel, and the investigation was cursory, but food for thought...

Further informations, it's written in:
- OACI doc
- EASA doc
- A340 abnormal proc
- A 380 abnormal proc
- A350 abnormal proc
- B 744 abnormal proc etc....
It seems to be everywhere but in 777/787 doc. Are those aircrafts lightning-proof?
