When a plane dumps fuel in order to lighten up for a premature landing, what happens to that jet fuel? Is it harmful to the environment? How quickly does it disperse? It seems to me that dumping almost 100,000 lbs of fuel would be an environmental nightmare. How about the risk of fire? How volatile is that fuel?

My understanding is that the fuel is effectively dispersed into the atmosphere and essentially evapourates away and never actually hits the ground. I don't really know what it's effects are on the environment, but a crash wouldn't exactly be great either, so...

During customer acceptance flights the fuel dump system is tested and it is amazing to watch all that fuel going out the port, but it must dissipate in the atmosphere (but I'm sure it's not good for the enviroment) because I've never heard of any public outcry on the issue locally. Jet fuel is actually pretty hard to light especially in the cold thin air where we do the test and haven't heard of any significant safety concerns from the engineering staff.

Hey Yaki,

Nice to hear you have an E-type, I've been thinking about picking up a 4.2 roadster, but I might to too much of an animal at this age to treat it properly. I see you joined the forum recently, welcome, nice to have you here.

when fuel hits the air @ x thousands of feet it never even sees the light of ground. imagine if you dumped a bottle of water out of a plane @ 15,000 feet. no one on the ground would even get a mist. plus, gas has a very high octane content (espacially jet fuel), and also has some alcohol, so both of them evaporate very quickly.

Thanks. The 4.2 are fantastic but like you say maybe a major project, Mine is a V12 roadster more of a gran tourer, as long as you don't have to much luggage.

This topic was in the forum a couple of months back and people said the fuel vaporizes within 5000ft.
