The Proposed New Standard for Location of Lightning Strike Zones on Aircraft 1999-01-2390
As part of an update of all of the lightning-related advisory materials for aircraft certification purposes, SAE Committee AE4L and EUROCAE Working Group 31 have completed preparation of a new standard for location of lightning strike zones on aircraft surfaces [Ref. 1]. This new standard is intended to replace the zoning guidelines presently found in US FAA Advisory Circular 20-53A (for fuel systems) and 20-136 (for electronics systems) and in certain military standards, and is known as “the zoning standard”.
The new Zoning Standard includes clearer definitions of the lightning strike zones and adds a transition zone between presently defined Zones 1A and 2A. Much of the document addresses the methods to locate the various zones in aircraft and helicopters. This standard, together with a new Environment Standard and updates of the existing FAA AC’s on lightning protection certification, are expected to be formally adopted by the FAA and JAA. In the interim, they are being published in the US by SAE and in Europe by EUROCAE for use by airframe and equipment manufacturers in the lightning protection design and certification process.
