Book excerpt: The environment and test waveforms defined in this SAE Aerospace Recommended Practice (ARP) account for the best lightning data and analysis currently available. The quantified environment and levels herein represent the minimum currently required by certifying authorities, consistent with the approach applied in related lightning documents.Lightning, like other weather phenomenon, is probabilistic in nature. Levels and waveforms vary considerably from one flash to the next. Within this document, standardized voltage and current waveforms have been derived to represent the lightning environment external to an aircraft. These standardized waveforms are used to assess the effects of lightning on aircraft. The standardized external current waveforms have in turn been used to derive standardized transient voltage and current test waveforms that can be expected to appear on cable bundles and at equipment interfaces within an aircraft. When deriving these latter internal induced test waveforms, considerations such as testability and important waveform characteristics that can demonstrate lightning design effectiveness, have been taken into account.The parameters of the standardized waveforms, both external and derived internal induced transients, represent severe versions of each of the characteristics of natural lightning flashes and include all parameters of interest with respect to lightning protection for aircraft. These standardized waveforms are thus referred to as idealized standard lightning environment waveforms, idealized standard waveforms, or just idealized waveforms within this document. The waveforms associated with the external environment are termed, the idealized standard external lightning environment. The waveforms associated with the internal induced environment are termed the idealized standard induced transient waveforms.In every case more severe versions of each of the individual characteristics of the idealized standard external lightning environment waveforms have been recorded in natural lightning flashes. The more severe individual characteristics of the idealized standard external lightning environment waveforms have never been recorded together within a single lightning flash. Therefore the parameters combined in the idealized standard lightning environment waveforms provided in this document represent a very severe environment.The waveforms provided in this ARP are considered to be adequate for the demonstration of compliance for the protection of an aircraft and its systems against the lightning environment and should be applied in accordance with the aircraft lightning strike zones (see ARP5414) and test methods (see ARP5416), and applicable FAA and EASA advisory and interpretive material. This revision was published to update the certification lightning environment as required to reflect the current state of knowledge and address issues as identified by the aerospace community. This involved the update of lightning parameter information and the modification of the standard waveforms.Due to the extensive re-work and re-organization of this revision the standard change bar' indications for the changes are not shown; therefore, an R' has been placed before the document title.

Book excerpt: This document is one of a set covering the whole spectrum of aircraft interaction with lightning. This document is intended to describe how to conduct lightning direct effects tests and indirect system upset effects tests. Indirect effects upset and damage tolerance tests for individual equipment items are addressed in DO-160/ED-14. Documents relating to other aspects of the certification process, including definition of the lightning environment, zoning, and indirect effects certification are listed in Section 2.This document presents test techniques for simulated lightning testing of aircraft and the associated systems. This document does not include design criteria nor does it specify which items should or should not be tested. Acceptable levels of damage and/or pass/fail criteria for the qualification tests must be approved by the cognizant certification authority for each particular case. When lightning tests are a part of a certification plan, the test methods described herein are an acceptable means, but not the only means, of meeting the test requirements of the certification plan.Each test method is set out in a uniform format, describing the test purpose, test object, test setup, test waveforms (voltage and/or current), measurements and data recording, test procedure and data interpretation. Guidance is provided on how to select the appropriate test or series of tests, and how the test results can be assessed.Natural lightning is a complex and variable phenomenon and its interaction with different types of vehicles may be manifested in many different ways. It is not intended that every test described herein be applied to every system requiring lightning verification tests. The document is written so that specific aspects of the environment can be called out for each specific program as dictated by the vehicle design, performance and mission constraints.

Available in PDF, EPUB and Kindle. Book excerpt: This book is an attempt to present under one cover the current state of knowledge concerning the potential lightning effects on aircraft and that means that are available to designers and operators to protect against these effects. The impetus for writing this book springs from two sources- the increased use of nonmetallic materials in the structure of aircraft and the constant trend toward using electronic equipment to handle flight-critical control and navigation function.

This book was released on 2022-02-11 with total page 314 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book gives a contemporary and comprehensive overview of the physics of lightning and protection systems, based on nearly 40 years of research, teaching, and consultancy work in this area. The book begins with an overview of the climatology of lightning and electric storms, as well as giving insight into lightning discharge from the preliminary discharges or processes such as corona, stepped leader, and subsequent return strokes, including the important submicrosecond threats and continuous current. The subsequent chapters present measures of lightning threat analysis to aircraft and electric power systems, protection measures to be used in high-voltage to low-voltage computer and communication systems, as well as to commercial and domestic buildings. The book discusses challenges posed by the submicrosecond lighting current changes and climate change to present and future high-voltage apparatus and structures (including carbon composite aircraft and new buildings) exposed to lightning strikes. Including worked examples, illustrations, and detailed analysis, Lightening Engineering will be of interest to electrical engineers, as well as researchers and graduate students.
