Now is it just me - or did the AFS look completely unprepared for this event, Now i am not conversant in French at all so I assume that this was a testing exercise and the fire(s) which going by the video (I assume) was reasonably expected to occur??...

Good thing he remembered not to approach laterally at least.....

I did see a second hose eventually attacking the Right MLG, but the Left seems to have been forgotten completely..

:confused: :confused: :confused:

Could somebody fluent in French translate for us what the guy is shouting...
I understood only:

"Get the ladder, where is the ladder, we need a ladder,
we have to evacuate them, get the ladder...
O, bitch (Oh, putin)...
Get the ladder..."

:eek: :eek:

During such a test the AC is at the MTOW, so tanks full...
Could you imagine the flames reaching a little higher...
What chances for the crew ???

:ugh:

The 777 RTO test was relatively uneventful:

That tape is an excellent reminded of why you never, ever approach a hot tire/brake from the side. If fact, just don't get near the blasted things in any case.

It is funny watching the poor lonely firefighter trying to get more pressure for his hose.

Isn't PPRuNe amazing. Where else could you get such excellent analysis from experts of both fire fighting and aircraft testing.

It really is amazing.

This was one of the certification RTO/ EVAC test for the A340-600. The voices one hear are those of the test pilots who first do not want the fireman to extinguish the fire as time has to be measured and for the test to be successful it must not be less than 180 seconds I think.
The lone fireman so early is in fact a nuisance .

What did go wrong in this test is that the Tyres fuses did malfunction .

Later when the fires are larger and have to be estinguished, there were far more firemen , but approaching from behind and invisible by the video camera.

The ladder request is for the crew to exit the plane ( foreseen but not in place ) I do not think this was meant for public diffusion.
In fact this iwhole thing is part of a normal testing process.

Good Grief
 

What happened to the fusible plugs - they clearly didn't function. I was alway taught that brake fires are best dealt with by dry powder extinguishers, to avoid thermal shock and exploding wheels - especially when the fusible plugs malfunction.

Oh My Goodness!
 

I am a volunteer fire fighter and can tell you for sure, some butts should be kicked in the post event debrief.

No pressure, insufficient hose length, one man alone (where was his partner?), the list goes on. :ugh:

Very interesting video though. :ok:

for a brake fire, yes, powder is good, but you must be prepared to back it up with foam/water spray, should it escalate. powder is only effective whilst in use, has no burnback resistance nor cooling qualities. with tyres involved, only water/foam spray is going to be effective, with powder or halon available should hydraulic lines fail, releasing free flowing flammable liqiuds to create a "three dimensional" or "running fuel" fire. glad the fire fighters remembered their correct positioning.:ok:

Results here ;-)

I don't know what was worse the Airbus or the French fire fighters!

Great link!

If it ain't Boeing I ain't going!

He's not asking for the ladder....he is asking for the stairs.

French firefighters.....Sapeurs Pompiers.....are fantastic, brave men and women.



....Putain mean wh*re by the way.

Clarence, irrespective of the collective expert analysis of the previous
posters, only an extremely patriotic Frenchman could draw anything
positive from quality fuse plugs fitted to this A340.
I sure hope the French nuclear reactors did'nt get the same batch!

I was not aware, that North Carolina is still french. (Thats where the wheel manufacturer Goodrich is based....)

According to a Learmount-reported article in Flight International, duped to Flight Global, the problem wasn't the fuze plugs' failure to operate at a low enough temperature, but rather the wheels' failure to withstand the strain of the increased tyre pressure. Je te jure!

OMG, I have just wet myself.:D :D :D :D :D :D :D

zzzzzzzzzzzzzzzzzz.................

Sleep well my high school educated little friend.

Je ne sais pas

Watch the 777 RTO test and you will see firemen who are better organized, the French fireys in the Airbus video scared me. :eek:

In all seriousness, I would hate to have a real RTO at that airport. And to make things worse for them, they knew ahead of time what was going to happen and should have been prepared for it.

Farrell: French firefighters probably are fantastic, brave men & women. They did not demonstrate this on the day of the test though.

Volume: I assume the 340-600 wheels were made by Goodrich to Airbus specification?
