F-111 flaming move

I got to see F-111 do the exact moves during the River Fire festival in Brissy just last year. They did it at night with plenty of fireworks.

In the Asian Aerospace 2004 there is a part where the F-111 created a flaming tail near the rear end of the engines by dumping fuel on the hot exhaust. I wonder if this have any combat purpose or is it just a stunt. Very Happy

Or was it a mis-fire?

Gee... hope no accident will occur

I may be wrong....but the only practical purpose i can think of...is to reduce the extra weight of the plane for landing.

More of a stun....but it looks cool !! Mr. Green

bismarck SG

it’s actually to reduce weight because the plane may be too heavy for landing and may just snap the landing gears. quoted frm a engineering student

Gedanken SG

Viper might have to correct me on this, but I believe if you know you’re coming in for a crash landing, standard procedure is to drop all ordinance and dump fuel, to minimise the likelihood of a fire or explosion after the crash.

kopiosatu SG

it's dumping fuel to meet the landing weight requirement (emergency)...

but people who were sitting around me kept saying it was afterburner

eurofighter SG

This acrobatic manoueure is called the ‘dump and burn’. Really popular back at home.

sgFish SG

yep its the dump and burn.. carrier pilots do it to meet the maximum weight requirements for the carrier landing..but dunno whether they ignite the fuel or just dump it..

kopiosatu SG

most of the time i hear about the aircraft just dumping fuel into the sea... not sure if burning was part of it.

Viper52 SG

You're right, dumping extra fuel is part of the procedure when aircraft have to make an emergency landing, but burning fuel is certainly not part of it.

The Dump and Burn made by the RAAF Pig at AA is part of their display routine. It is done by simply dumping fuel and lighting the afterburners. Mix open flame with a stream of volatile avgas streaming out behind the aircraft and voila! Dump and Burn!

Because of the location of the Pig's fuel dump (lower fuselage between the exhausts - see attached pic), it is one of few planes able to do this safely. Still its a forbidden stunt in the USAF (when they operated -111s) and only practiced by the Aussies

cavsg SG

actually you dun need to have an emergency in order to dump fuel to land, there maybe technical problems on the plane that may affect the safe arrival to the destination like nav problems or aircon failure. why commercial pilots dump fuel is becos the landing speed is higher and the chances of a brake fire is greater, also the landing distance is longer, if you need to go around, you dun have much runway length to play with. commercial aircraft landing gear can land at max takeoff weight if there is a real emergency and there is no time to dump fuel.

love the ozzies for their chutzpah

nismoS132 SG

everytime dump fuel waste $ leh

kopiosatu SG

hahahaha, u dunno how much fuel is wasted... not just on dumping...

there's water particle test too...

SingaporeTyrannosaur SG

Stupid... on Sunday the F-111 flew too low and everybody who paid to be in the exibition center didn't see the burn, but the people on the beach did... Mad

Bochupi SG

maybe the pilot saw someone at the beach having trouble starting his BBQ and decided to help him a bit? Mr. Green

Moonstriker SG

lmao

eurofighter SG

No wonder I couldn't see it. Taught it was not performed due to time constraints-the apache was hovering in the air not too far away, waiting for it's turn.

tankee1981 SG

Thats true i went on Sunday and was expecting to see this live. However i didn't see anything and i thought i missed it or due to the blinding sun. Very Happy

SingaporeTyrannosaur SG

If you listened to the guy giving the commentary, he'll go "Alright ladies and gentlemen, keep your eyes straight in front of you..." just when the F-111 flies out of sight behind the building. And then "There! Isn't that spectular? The famous dump and burn move!"

Of course, all we saw was empty skies...

Sigh...
