Nope, the attatchement is no diffterent the from an other plane.
Both back- and frontwheels are attatched to the bogey. The bogey is then attatched to the main wing structure.

Andries wrote:The answer is that the fluorecent fluid is an indicator fluid. Whenever a discharge of static electricity occurs (ussually at the wingtips) there is also some fire-extinguishing fluid released into the Fuel-jettison-pipe.
When this fluid is released, the fluorecent fluid is also released and creates a fluorecent spot on the underside of the wing. When a mechanic then checks the aircraft he should notice the spot, he should know what to do.
Hello Andries,
I'm sorry but I never heard about such a fire-extinguishing fluid :( . Also, all aircrafts are equiped with flame arrestor on fuel vents (also used as jettison pipe).

Could you provide us a link?

Sorry Seb. Can't provide you with a link, cause it's something we learned during our lessons on the 727 (KHBO @ EBOS).
Same as the current question. We learned the answer during our lessons Aviation Technology.

Ok, I never worked on B727s, so it explain everything.

I am confusing myself: jettison pipe = transfert pipe, not fuel vent...

Could it be that the gear is tilted forward to fit in the wheel well?

the landing gear trucks are canted that way for one reason, so they can fit in the wheel wells.
if they are not tilted that way, the gear cannot be retracted. the odd looking tilt is held in that position by a 3000psi hydraulic actuator, which the aircraft weight on wheels can easily override.

Yes, I googled a while. :D

Indeed, the explanation Rotor gave us is 100% correct, even the hydraulic pressure :) It all depends on what space is left to place the gear in. on 767 they had to tilt it forward.
Nevertheless, MD-11 was the first to give the correct anwser.

MD-11, it's your turn !

You have got 2 spellings of wheels here sab & they are both wrong, it should be spelt "wheels."

Okay, there are three classes of aircraft concerning their weight, according to ICAO Internat.specifications.
What are those three classes called and until what weight do they go.
So I want three "names"and a weight with each class, in tons or in lbs.
Good luck
PS.: Not hard to find, I guess :wink:

No problem ;) Let' me try again. I think I had the classification from the US in my previous post.

So here we go again and in tons this time ;)

Heavy: 136tons < MTOW
Medium: 7tons<MTOW<136tons
Light: MTOW <= 7tons

Both correct, but Avro was faster, so it's his turn 8)

I assume you are talking about the high pressure compressor?

>9 stages.
