In reading about software and equipment design for aircraft I'm finding a lot of references to various standards like "DO-178B, Software Considerations in Airborne Systems and Equipment Certification", but I'm having a hard time finding copies of these.

Is there a central repository or location where I can review or purchase these standards?

    $\begingroup$ This question appears to be off-topic because it is about resource location. The document is not that hard to find in the RTCA online store or in the EUROCAE online boutique (as ED-12B). $\endgroup$

  • $\begingroup$ I don't think this is an exact duplicate of that question. The suggested original is asking about FAA regs dealing with software to do with flying, whether it runs on the aircraft or not. This question is specifically about software that runs on the aircraft, and it asks about relevant standards, not regulations. $\endgroup$

Many of these are Radio Technical Commission for Aeronautics (RTCA) standards.
You can get these documents from the RTCA website. They are provided free of charge to RTCA members, non-members have to pay.

Alternatively you can acquire the European equivalents from EUROCAE (RTCA DO-178B is ED-12B in the EUROCAE eShop).

If you want to be up-to-date (for example if you're building a new avionics system), you should buy the latest version of the standard, such as DO-178C / ED-12C, which is the latest edition of your example above (published in 2012).
