What it is
What STANAG 4702 covers
STANAG 4702 is the NATO standardization agreement that gives force to AEP-80, Edition B, the Allied Engineering Publication setting airworthiness requirements for rotary-wing unmanned aircraft systems. A STANAG is not itself a technical specification: it is the agreement by which NATO nations commit to implement one, and the actual requirements sit in the Allied Publication it covers. This STANAG responds to an interoperability requirement stated plainly in the document: "To use common standards for the production of airworthiness requirements for Rotary Wing Unmanned Aerial Systems." Read plainly, that means the STANAG exists so that NATO nations design and certify rotary-wing military UAS against a shared airworthiness code, not so that a single national standard applies everywhere automatically.
This is Edition 2, promulgated 24 November 2016. It supersedes STANAG 4702 Edition 1.
Who ratifies it, and how it takes effect
The mechanism that matters here: a STANAG binds a nation, not a manufacturer. Nations "are invited to examine their ratification of the STANAG and, if they have not already done so, advise the NSO of their intention regarding its implementation," and the national response is recorded in the NATO Standardization Document Database (NSDD). Once ratified, "This STANAG is effective upon receipt and ready to be used by the implementing nations and NATO bodies," and partner nations "are invited to adopt this STANAG." The document also names a more specific implementation test: it "is considered to be implemented when qualification and proficiency standards described in this standard are acknowledged and implemented into national regulations and manuals." A manufacturer meets AEP-80 only where a contract or a tender brings it in by name, not because the STANAG exists on its own.
Reporting and review
Nations report their effective implementation "using the form in Annex H to AAP-03(J)"; partner nations report their adoption of the STANAG the same way, "using the form in Annex G to AAP-03(J)." The STANAG "is to be reviewed at least once every three years," with the result "recorded within the NSDD," and nations or NATO bodies may propose changes at any time through a standardization proposal to the tasking authority.
How it's evaluated
No certification exists here, and the document names none. What it describes is a national ratification, implementation and review cycle run through NATO's own machinery, not an audit against this STANAG as such. The airworthiness requirements in AEP-80, and how a national authority applies them to a specific aircraft type, are that publication's subject, not this cover agreement's.
