I read somewhere that that is the coffee dump valve - theres a pic of a VS 744 with a dodgy looking underside - its a coffee dump I understand.

Other than the cofee stain, that aircraft looks pretty spotless.

Don't worry, AF leaves skidmarks too.

No such thing.

It is a Drain mast. Basically any liquid waste that is not human is dumped overboard via the drain masts on the bottom of the a/c, all the waste water that goes down the sink in both the lav's and the galleys flows out of the mast and into the airflow which is what causes the streaks on the bottom.

Some airlines encourage crew to empty the coffee/tea pots into the lav's which is then stored onboard to prevent the waste soiling the exterior of the a/c as shown in the pic.

This is what it looks like on the ground :-

You have to be careful walking around the a/c when it is windy as the liquid droplets disperse so they are not visible. If you walk past on the upwind side, then quite often it results in a not very nice shower !!!.

And this is what it looks like in the air :-

So if you're above some town you hate you pee to the sink?

BTW, how these masts work? How is possible that the A/C won't lose pressure trough them?

Why isn't this topic at least in Civ Av?

1) I guess so,  yes  !!.  yuck 

2) An a/c is not like a submarine, it doesn't have to be completely air tight. There will always be some air escaping somewhere in the structure, liek around the doors or windows for example or even out of the outflow valve. As long as the pressure leaking out is less than the air being pumped in then everything is ok.

3) No idea, thought that myself.

Not only making the plane dirty. Remember once having to bring a big tank of nitrogen into the galley of a DC9 to blow the drain clear. It was plugged from too much coffee being poured down there.

Had a pic, of this procedure, but unfortunately it's on a hard drive that went to hell.

That looks like it has come from the wheels/tyres rather than from the drain masts.

Quoting KaiGywer (Reply 12):

On our a/c there are notices telling the crew what can and cannot be poured down - do they read them - do they f**k !!. They regularly like to pour freshly squeezed orange juice down them, so all the bits of orange block the drains !!. Also if they pour red wine or milk down them, they are supposed to pour boiling water down afterwards to ensure that the milk and wine don't solidify in the pipes.

Damn that's dirty. Oh well, after this summer, unless DY is SIGNIFICANTLY cheaper than SK, I will stick to SK.

Yeah, that's what I thought... Although what causes those marks? How do the tyres come in contact with that part of the fuselage?

My guess would be repeated kicking up of sand/dirt from the runway, and nobody to clean the planes (ever).

Hmm, possible... although the stripes do look like rubber had been dragged along the fuselage. And it is only on the one side of the plane... and not above the undercarriage, where one might expect sand or dirt to get kicked up from the rwy...

Hmm... The only logical explanation I can think of is that another aircraft must have made a one wheel touch and go on the belly of the Norwegian plane while inverted in mid air.

Simple.  Smile
