Re: Fuel Dumping Does and Don'ts

Don't care what Airbus says, dumping in a thunderstorm doesn't sound like a very clever idea
What are you concerned with?? Do you really see any correlation between a solid stream of cold fuel from a nozzle, cold air and lightning as leading to a fire / explosion??

It is quite difficult to get Avtur to burn in the right circumstances (HP pumps, sprayers / vaporisers etc. into a compressed i.e. hot air scenario). I might expect an untrained passenger to imagine a lightning strike causing a "dumping fuel aircraft" to "explode" but am a little surprised (and disappointed) to see professional pilots succumbing to this viewpoint. IMHO the jettisoning stream at the nozzle could not be ignited, however hard you tried... see the F-111 routine where the full reheat plume can only get the dispersed part of the jettison stream to burn
