YELLOW and GREEN hydraulics

[ltl_mush]

I'm currently in a ARJ groundschool. We just finished up with hydraulics. Can anyone tell me WHY they call the two different systems YELLOW and GREEN? Why not left or right? Or blue and red? I understand how the system operates but can't figure out why they call it YELLOW and GREEN. Thanks for your help.

It's for when there is a hydraulic leak. You can tell which system is leaking by the color of the fluid on the ground.

First, welcome to Mesaba. You'll love the Avro, she might be fat, she might be slow, but she's one h#elluva woman! You'll have a blast.

Second, here's a rule of thumb when trying to understand the logic on the plane. IT'S BRITISH! Having said that, you'll find some very interesting BacJet-isms. We might poke fun at the British logic, but it's a very well built and laid out plane. They did a nice job. Some of the quirks are actually American stuff, so not much room for our judgement eh?

To answer your question... I haven't a clue. But I'm sure if you ask D. Wilson, he'd be more than happy to help you out.

Have fun at a/c training... you'll love it. How many 90,000 pound planes have you ever (or will ever) do touch and go's in?

Glad to have you onboard and we'll see you online. Where will you be based?

Thanks for the insight Flap Operator. I'll be based in DTW to answer your question. Can't wait to get on the line! (reserve)

Ask one of the Airbus drivers on here what they call the three hydraulic systems on that aircraft?

BTW...who cares what they call it? It's just a name. A way to differentiate one from another. It could be left, right or center. Or one, two and three. Or red, green and yellow. Or schvantz, warnk, and putz. Like I said. It's just a name. I would think if all you had to worry about in groundschool is WHY the hydraulic systems are called yellow and green instead of red and blue, then you must have a great handle on the material. Congrats!!

It is just a question that they asked us to find out and I'm also curious myself.

Sounds like a typical ground instructor "answerless question to drive you mad"

I might be inclined to agree with you on that. But, even though I'm not really a ground school instructor...although I do the occasional Continuing Qual (recurrent in the non-AQP world), I'm primarily a sim (fixed base and full flight) instructor after 25 years of line flying and instuction experience, and now have a full time management position in the training deparment of a major airline, I can't imagine ever throwing something out there like that "just because". It serves no purpose, and I'd rather the students concentrate on things that actually mean something and come into play in the real world. They have enough to worry about without having things thrown out there "just to drive them mad". I'd rather they come away with useful information than trivial BS. But, that's just me. I know the type you are referring too, though. I'd rather you actually learn something, than to try and impress you with my vast knowledge of obscure, trivial BS.

So the next time they ask you something like that, the proper answer is "who cares?"

 

[flap operator]

Itl Mush - who's teaching your ground school? That is a lot of plane to handle coming from a GA background. Information like that, while interesting to know, is as the previous poster said, a waste of your time right now. Your job is to eat, sleep and crap the avro. Once on the line after your first PC you can worry about the trivial gee wiz stuff. It certainly isn't going to get you that S on your initial PC eval form.

In the helicopter world, there are no L or R rotor blades; they are color coded for ease of identification.

If you intermix systems for redundancy, like hydraulics, to the L and R sides, it is easier for maintenance to distinguish which is which without following a line to its source.

That's my guess. Greasy side down....

[Ace McCoy]

It's really quite easy...Yellow is on the left side. Yellow has an L in it so does left. Green is on the right and both green and right has an r.

But what you should really be asking is why have auto-throttles and no VNAV? Makes lazy pilots?

 

[flap operator]

Actually, it without VNAV you actually have to plan a decent. So you can't get complacent or else you may not make a crossing restriction. Hardly a lazy pilot that makes.

does the avro have auto throttles or a TMS?

 

[flx757]

It is just a question that they asked us to find out and I'm also curious myself.

If "they" you mean the training dept, then I feel for you. Obviously, "they" don't have anything better to do, either...or they are trying to impress you with how much "they" know. Not a good combination for instructors/check airmen. Then again, you often run into these types who are on a power trip instead of realizing their mission is to provide you with the best tools available, and give you the best chance at success. Training should not be a "guessing game". There should be no "secrets". It is a learning experience.

Again, good luck.

The avro has autothrottles and is cat III equipped. Autoland is pretty bad a$$!!

You know even though the two hydraulic systems are independant there is a way to tranfer fluids between them.

a good thing too! i would think it would be a lot harder to fly if there were L or R rotor blades.. if it did have L or R rotor blades, wouldnt that make it fixed wing?

choppengruven: i dont know about this plane's systems, but my guess would be thru the brake system.

 

[choppengruven]

Your guess would be right. good answer

 

[dash8driver]

how many points do i get?

 

[choppengruven]

No points but if you want you too can be hired by Mesaba and make 18,000 a year and sit reserve in MEM and DET for the rest of your life. cmon live the dream and wear the hat.
