a.   This advisory circular (AC) recognizes several SAE Aerospace Recommended Practices (ARPs) and European Organization for Civil Aviation Equipment (EUROCAE)documents as acceptable methods for showing compliance with airworthiness regulations.  These industry documents provide guidance on aircraft lightning environment and test waveforms, aircraft lightning zoning, aircraft lightning test methods, and aircraft lightning direct effects.     

b.   This AC is not mandatory and does not constitute a regulation.  It describes an acceptable means, but is not the only means, to help you to obtain certification for lightning protection.
