Jezz 0 Posted February 21, 2005 legend has it that the fuel dumping is why the donington race circuit in england used to be so slipperly, i think it was donington. The dump and burn is impressive but its pretty pointless but hey it looks cool Share this post Link to post Share on other sites
Acecombat 0 Posted February 21, 2005 Ok never thought that the plane stored its fuel in wings thought it had it in its underbelly somewhere around the middle part.As for that extreme example is that Mig ( looks like it the airframe doesnt looks like the f-14?) dumping its fuel from the back and then burning it by his heat exhaust from the engine? Â Or have i got it wrong? It's an F-111.....the 'dump and burn' is a method which I believe is exclusive to that aircraft. You can even try it out in OFP with Skaircro's F-111, which is available:here! Yeah F-111 it has that same look to it as well . Share this post Link to post Share on other sites
BlackScorpion 0 Posted February 21, 2005 Well... The "Dump and burn" thing is called afterburner (Ever heard? ), generally, afterburner is fuel injected to the very hot exhaust air, dunno if it's actually flames but... And you sure the KC-135 is actually dumping fuel? I've seen that pic before... Share this post Link to post Share on other sites
Tovarish 0 Posted February 21, 2005 Well... The "Dump and burn" thing is called afterburner (Ever heard? ) No...dump and burn involves dumping fuel (on the F-111 this is done between the engines) and then setting the jetissoned fuel alight using the afterburner, after the fuel has left the aircraft. As ozanzac said, only the F-111 can do this because of the unique location of the fuel dump nozzle between the engines. Unlike afterburner, the dump and burn does not provide any extra thrust.

dm 9 Posted February 21, 2005 Civil aircraft dont actually have a capability to jettison "excess" fuel. Its all in the wording (or reading) of the statement: Quote[/b] ]The plane is circling above East Kent to get rid of fuel, before attempting to land. Meaning that the aircraft is simply circling above Kent while the engines burn all that "extra" fuel. Share this post Link to post Share on other sites

HotShot 0 Posted February 21, 2005 Where do they dump it? Exclusivly in the sea, or do they sometimes dump it over land if no sea in the area? Share this post Link to post Share on other sites
Akira 0 Posted February 21, 2005 Where do they dump it? Exclusivly in the sea, or do they sometimes dump it over land if no sea in the area? It would depend. Every airport has a designated area as required by their Emergency Action Plan. It can be over sea or land, populated or unpopulated, but as someone pointed out, generally Avgas will disipate in the air before it reaches the ground.

stevevcb 3 Posted February 21, 2005 Okay, we've all agreed that yes, airliners can jettison fuel. However, like Deadmeat and Messiah(?) have both said, the plane was just circling Kent to use the excess fuel up, not to dump it. Share this post Link to post Share on other sites

dm 9 Posted February 21, 2005 Planes don't have an AUTO-HOVER option, you know. The forum seems to have an "Auto-Spam" option tho Reguards to the fuel-dumping thats my bad, I assumed with the new fuel regulations, that aircraft are no longer allowed to jettison fuel over any land-mass. And that civil aircraft were no longer allowed to undertake fuel dumping (I'll have to read up on the regs my end) don't quote me on that one. As for the circling, that is a very very common practice, to have an aircraft orbit an airfield (usually in a very large orbit, so as not to interfere with the "normal" pattern) in order to burn off fuel. And no Avon, they don't have an auto-hover function, thats what the pilots are there for (although you could program a modern nav computer to take up an orbit very easily) Share this post Link to post Share on other sites

If it is not an immediate emergency, as this case was, it is common for the plane to circle at a holding location while the pilots assess and try to fix whatever the problem is, in this case a landing gear problem. Where the emergency requires immediate landing, planes will dump fuel prior to re-entering the landing pattern. If you look on AirDisaster.com, there is a video from inside a 747. It's taking off and has an engine failure. The video shows the plane circling and has a good shot of the fuel dump taking place. I would be surprised if regulations prohibit fuel-dumping, as most planes, in the case of emergencies upon take-off, have to dump fuel in order to land safely.

Was on a 727, one of the leading edge flaps failed to retract on one side, so we circled for 90 minutes burning off fuel (instead of dumping) and made a normal landing back at the airfield.

One time a chinook flew really low over the house that every thing shook. I live right next to Camp Mabry, and every god damn Sunday they take off in their Blackhawks and head out for their weekly BBQ. And I live right under the flight path for the landing on ABIA 17R. Course being a plane dork I don't mind so much. I can tell you exactly when a SW flight comes in. Share this post Link to post Share on other sites

Â ), generally, afterburner is fuel injected to the very hot exhaust air, dunno if it's actually flames but...And you sure the KC-135 is actually dumping fuel? I've seen that pic before... Tovarish already backed me up for the first half (Cheers mate. ).....and I bet you'd strugle to distinguish an engine fire (ever heard ) from normal AB operations if you think that's an AB..... As for the second half.....I will, however, give you the concession, that it is not a tanker... There was a lack of images of civilian aircraft I could find that effectivly showed the aircraft dumping fuel, and before finding a picture, I typed up the post, looking for a military tanker dumping fuel, but this picture was an even better example....I merely forgot to edit out the tanker bit, as I was in a rush to get to work...... The aircraft pictured is not a KC-135 (as you claimed) *note lack of central controlled boom, but actually an E6A, which is basically, the Navy modified version of the USAF E8 command and control aircraft. (Itself based upon the Boeing 707) And yes, the designation is right....it's E6A...not A6E....and yes it is dumping fuel....because the wingtips are jammed full of electronics...thus the fuel jettison port is not in a standard position, but then again, it's more standard than a KC-135, which is capable of dumping fuel via it's boom.....which is hardly normal in comparison to normal aircraft at all.
