2.0 TDP Variants and NAS Elements
The data medium for a TDP can range from legacy 2D paper to CAD images and solid modelsSimilarly, the medium for preparation and transmittal of a TDP can range from paper/fax/mail to the mostsophisticated forms of electronics.
Although model-centric efforts are emerging as the norm for current new product development andacquisition, a substantial level of TDP activity is based on legacy data for which no computer-generateddata exists. In a mode-centric environment, the full TDP reflects a range of documents and otherinformation that typically resides outside the master model. These must be properly captured andconveyed to ensure that a NAS-compliant TDP is established. In a legacy environment, key data canrange from ambiguous, to unavailable, to illegible, depending on the age and nature of the data.Therisks inherent with such data must be documented and understood by all those involved in acquiring anddelivering a product if a NAS-compliant TDP is to be realized.
This Standard considers the full range of TDP variants, from the oldest legacy systems to new productscurrently in concept definition. The realization of a NAS-compliant TDP is not dependent on the age orthe format of the data. Rather, compliance is based on completeness and adequacy of the TDFregardless of when it was generated, how it is delivered, or in what medium it is provided.
2.1 Applicability for TDP Variants and Aerospace Products
This standard applies to TDPs for build-to-print and source controlled products. Build-to-print are thosedesigns provided to the source (either internal or external supplier) by the prime or other engineeringsource (e.g., Government agency). Source controlled are those products for which a supplier hasdesign authority and which are provided to a customer based on a performance specification, statementof work.or similar document.
This standard is applicable to all aerospace products that meet these criteria, for all stages of theproduct lifecycle, including concept definition, preliminary design, detailed design & validation,production & deployment, and support & maintenance. This standard can be applied by primes orGovernment agencies as they flow TDPs to their supply chains. An important aspect of the Standard isits bi-directional feature, enabling suppliers (i.e., “recipients”) to consistently review the level ofcompliance of the TDPs they receive from their customers (i.e., “senders”), and accept or seekclarification, based on completeness, accuracy, and other criteria. Through this feature the Standard wihelp customers and their suppliers set expectations and manage risk. Use of this Standard will facilitatemission assurance by clearly isolating and collaboratively addressing specific areas of risk.
2.2 NAS Elements
To enable characteristic accountability and achieve mission assurance, the focus of this standard goesbeyond simply the content of the TDP. While content is essential, the full realization of a successful TDP is dependent on communication and application as well. Compliance elements are composition, communication, and application. They are described in the succeeding sections.
