There is a web site for RTCA which lists the current revisions and the prices, http://www.rtca.org/nonmember/ from just checking the site, the latest revision is DO-160D. Stefen J.

Re: EMC and Safety of equipment used in aircraft
Something you may wish to consider. Some years ago the U.S. army and navy both contracted for similar helicopters, but to separate specs. The army version was the blackhawk, as I recall. The navy version was required to be far more immune to EMI, as the navy was well aware of EMI problems due to their experiences with severe EMI congestion of shipboard electronics. Namely lots of emitters and receivers within a small area. The army spec was less rigorous in this regard. As a result, the army version could, and did ocassionally, crash due to the EMI from a mere TV or radio tower in the vicinity. MORAL: Beware of EMI from devices operated within commercial aircraft, whose EMS is far worse than aircraft designed for military battle conditions.
