Need Facts on Airline Cabin Window Modules 1

[See1111]

I require (with references?) some basic attributes of major airline cabin windows (474, 757, etc.) such as:

o Total window weight (including sandwiched glass/plastic, metal frame, gaskets, rivets, etc.)
o Off-setting fuselage weight for same opening (if there were no window) - what does the window add net?
o Cost range of above complete window assembly (wholesale)
o Average maintenance cost per window per year
o Cost to replace a damaged window
o Window failure rate (total replacement) per year
o Comparison of passenger (with windows) fuselage costs to cargo (no windows) costs - all other things equal.

Thanks for your help. Perhaps you could also recommend a few good airliner engineering University departments or other sources or reference for basic napkin calculations.

Best Regards,

Are you serious??

If I worked for Boeing and had a legitimate need for this type of info it would be very difficult at best to obtain.

What do you need this info for and what it is worth to you?

SW,

The answer to *your* question is *free*! They throw in the SRM when you spend the $19M on a used 57!

Wes - yes, you get a "free" SRM with each a/p purchase. But the SRM isn't going to have the info the OP is looking for.

I dont think that anybody will have the specific things your looking for. Even if they did, they wouldn't give it to you.
May i out of curiosity ask why you need it? Maybe we could then give a more generalised answer which might help?

SW - That's true, I guess I should have said, "a subscription to Mybeoingfleet." That would do it.... it was late last night, and my daughter was keeping me up.

Got my boeingfleet access, and you can get some of the SRM's, IPC's etc, but it wouldn't help the OP.
A miracle would get the OP there answer.

Thanks for your time guys. I just figured one of you 'rocket scientists' might know some basic cabin window attributes and be able to reply with something like: "Oh yea, a 757 type cabin window subassembly weighs about 12 LBS, costs about $1800 (wholesale). Inspection & maintenance runs about $300 per year, $1200 to repair/restore - 3% per year, and a complete replacement costs about $2500 in labor with a 0.5% replacement rate per year, etc....

I have a consulting engagement that requires some basic cost assumptions. I can and will obtain this information, be it through an aeronautical consultancy, an engineering university, the FAA, Patents, Text Books, RFQs, and even buying a window subassembly from a bone-yard (via eBay for a few hundred bucks).

This was an 'easy' approach but I guess you get what you pay for! ;-) That's OK... just more billable research hours.

Thanks anyway.

Best Regards,

See1111:
I sense a feeling of sarcasm and dispondance.
As you seem to have zero knowledge about the field please let me clarify some things for you:
1)OEM's will not give you the information that you seek, you see it is propriety data.
2) the FAA do not know or care about the data that your looking for
3)With so many differing window assemblies on difering aircraft platforms you need to be specific to an aircraft type.
4) The weight of assemblies will only be known by the designers of the part, and the weights engineers involved, please refer to point (1).
5)You do not simply "buy" window assemblies like you do your groceries, therefore the cost of parts depends greatly upon the aircraft platform, how quick you require it, and how many you wish to purchase.
6) Inspection and maintenance depend upon how the aircraft is used in its life, what aircraft it is and where in teh world it flies to, never mind the basic economics that are involved in the pricing of such work.
7) How often these assemblies are damaged/replaced is not catelogued as stats
8)Text books will not give you the info for the same reasons i have stated above.
9) Universities wouldn't have a clue
10) Maybe you would understand that if you ask a stupid question, you will get a stupid answer. There is simply not the information documented that you require. And yes, before you harp on, the people here at this forum have forgotton more than you currently know. So please dont insinuate that just because we couldnt answer your daft question that people here arn't "rocket scientits" as you put it.
11) Student posting isnt encouraged here, the reason for your research is to learn something and bring something new to the industry.

I apologize if I inadvertently offended anyone. Just trying to have some fun while working.

I wanted a few very basic 'cabin windows' questions answered and figured a 'windows guy' could answer them off the top of his/her head, based on industry averages as used in most every trade-type magazine article.

I have over twenty years in Information Technology, not aeronautics, but thought you guys might help me out. I am certain that this basic information is available for a price. Like from Gartner Group for IT - they do include proprietary data in White Papers (but without disclosing the company) for benchmarking. You might want to know how does your window subassembly compare to competitors - participants see where they stand but the competitors (who also participated) are listed a 'Comp-A,' 'Comp-B,' 'Comp-C,' etc.

Anyway, I'll just be on my way, sufficiently chastised. And #11 was a cheap shot! School hasn't even started yet.

Thanks for your time, if not your hospitality.

(No reply necessary.)

There is something very wrong with this thread.

Somebody probably let a marketing puke in here.

The reliability people at most commercial carriers could pull this data together.

Over the years I've replaced a few, polished the scratches out on a few etc.

Some of your numbers don't look right.

Your customers will know, but they won't tell you.

All they want to know is the bottom line cost and if you can stick an 8130 on them.
