What are the current industry standards for the costs of manufacturing
business aircraft (jets) from prototype to production line? |

Are you looking for an average cost to bring a new business jet to
market? It will be a fuzzy number at best, I have a background in this
and might be able to find a few examples. I could go over estimation
techniques for cost-to-design. Production line is a little different.
It would depend on whether you had an existing factory, outsourced
some production, etc.
So... could you be a bit more specific on what you're looking for?
Could you describe a bit better what "process" you have in mind? There
are no "standards" per se.
Even with the information I am asking for it would take a great deal
of effort to come up a solid estimate of cost to design, build, and
produce.
If you were to narrow down the focus of your question a bit I should
be able to provide a satisfactory answer.

Price point for product will be between $1.5 & 2.5 million; Total
estimated production costs including
prototype/certification/production is between $300 and $400 million.
Assume will outsource production line utilizing excess capacity in
existing facility. Will produce 50 to 100 product per year initially.
Comparable product might include Smaller Lear Jets/larger Pipers/mid
range Cessnas. Attempting to provide a proforma with time frame for
ROI for investors to review.

So am I to understand that you are looking for comparisons to your
product? Comparing the numbers that you specified? e.g:
Mine Comp1 Comp2
Price Point:
Production Costs:
Units per Annum:
Supporting Data... etc...
Best,

krobert - I need to know how to allocate funding to the various
aspects of development to product launch - what % of the total (let's
assume my lump sums are adequate) is labor, what % toward engines,
what % is tooling? Then I can allocate for a pro forma.

Gotcha... Let me do some preliminaries on this and I'll get back to you.

krobert - also identify if possible what are the non-recurring (start
-up) expenses and the ongoing production costs. Thanks.

stumped50-ga,
Rather than provide this as an answer just yet, I will point you to
this publication by RAND:
http://www.rand.org/cgi-bin/Abstracts/ordi/getabbydoc.pl?doc=R-3255
It covers cost estimating the design, production, and maintenance
costs of aircraft (primarily military, but applicable to others).
From the abstract:
"It provides separate cost estimating relationships (CERs) for
engineering, tooling, manufacturing labor, and quality-control hours;
manufacturing material, development support, and flight-test cost; and
total program cost."
This looks like it fulfill your needs.
If this suffices as an answer, I'll post it as such. If you would
like me to take a stab at breaking down the costs for you I will need
more detailed information about the configuration of the aircraft.
The alternate source that I have (in my library, a stripped down
version of the RAND document), states that I will need such
information as the empty weight, max velocity, number of flight test
aircraft, turbine inlet temperature (based on my experience, I'm
guessing this is because the greater the temperature, the more
espensive the engine), and avionics cost (bulk), among others. It also
has some fudge factors that you can use to account for newer materials
and better R&D and production methods (say, improved tooling and
bigger and better CAD).
FYI, the RDT&E expenses (Research, Development, Test and Evaluation)
would be the start-up costs that you are asking for. This RAND
document covers estimating these as well.
Additional FYI, this document is about 14 years old, but aircraft
manufacturing tends to be a bit behind the times anyway you look at
it. Obviously, if inflation is not accounted for in the equations
listed in the document, they can be estimated from historical data.
Best Regards,
krobert-ga

Krobert - I have ordered the document. I think that is all I need for
now. Consider the question answered. Thank you.
