Aircraft Lightning Zoning

AE-2 Lightning Committee
  • Aerospace Standard
  • ARP5414B
  • Current
Published 2018-12-05 by SAE International in United States

This SAE Aerospace Recommended Practice (ARP) defines lightning strike zones and provides guidelines for locating them on particular aircraft, together with examples. The zone definitions and location guidelines described herein are applicable to Parts 23, 25, 27, and 29 aircraft. The zone location guidelines and examples are representative of in-flight lightning exposures.

Aircraft Precipitation Static Certification

AE-2 Lightning Committee
  • Aerospace Standard
  • ARP5672
  • Current
Published 2016-04-13 by SAE International in United States
Aircraft surface precipitation static (p-static) charge can be generated when aircraft fly through ice particles, rain, snow and dust. However, in the context of p-static protection, this document is used for providing guidance for any thing that charges the outer surface of the aircraft (e.g. engine exhaust). P-static discharges from the aircraft can disrupt aircraft communication, navigation, and surveillance radios, and can damage aircraft radomes and windshields. This SAE Aerospace Recommended Practice (ARP) defines design considerations for aircraft p-static control and related methods to verify acceptable aircraft p-static performance. This ARP addresses p-static charging due to the aircraft flying through ice particles, rain, snow and dust. It does not address other triboelectric charging that may be present in an aircraft, such as triboelectric fuel charging or environmental control system or air conditioning static charging. It does not address electrostatic charging created by passengers or crewmembers, or electrostatic discharge hazards to electronics and systems. The purpose of this document is to provide information and guidance concerning an acceptable means, but not the only means, of compliance…

Aircraft Lightning Environment and Related Test Waveforms

AE-2 Lightning Committee
  • Aerospace Standard
  • ARP5412B
  • Current
Published 2013-01-11 by SAE International in United States
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…

Aircraft Lightning Test Methods

AE-2 Lightning Committee
  • Aerospace Standard
  • ARP5416A
  • Current
Published 2013-01-07 by SAE International in United States
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,…

Aircraft Lightning Direct Effects Certification

AE-2 Lightning Committee
  • Aerospace Standard
  • ARP5577
  • Current
Published 2008-03-26 by SAE International in United States
This document provides guidance for a means of showing compliance with regulations for protection against lightning direct effects for aircraft of conventional design, as well as for those involving advanced composite structures or other new technologies. This guidance also applies to those aspects of aircraft systems and components not addressed in the regulations covering the protection of electrical/electronic systems (for example, FAR/JAR xx.1316) or fuel systems (for example, xx.954). The guidance provided in this document applies to initial designs as well as modifications.

User's Manual for Certification of Aircraft Electrical/Electronic Systems for the Indirect Effects of Lightning

AE-2 Lightning Committee
  • Aerospace Standard
  • ARP5415A
  • Current
Published 2008-02-16 by SAE International in United States
This user's manual provides additional information and references relevant to identifying: (1) acceptance criteria for the indirect effects of lightning compliance approaches, (2) verification (analysis and test) methods including those associated with multiple stroke and multiple burst and (3) recommended design options to optimize needed system immunity to lightning indirect effects. Equipment hazards addressed include those due to the indirect effects on equipment mounted on the aircraft exterior and equipment located within the aircraft interior as well as all associated interconnecting wiring. This document has specific application toward those topics and subsystems addressed in ARP5413 but also provides additional guidelines in the application of those tests identified in DO-160/ED-14, Section 22.

Certification of Aircraft Electrical/Electronic Systems for the Indirect Effects of Lightning

AE-2 Lightning Committee
  • Aerospace Standard
  • ARP5413
  • Historical
Published 2006-03-24 by SAE International in United States
This SAE Aerospace Recommended Practice (ARP) provides guidance for a means of showing compliance with the regulations for hazards caused by the lightning environment to electrical/electronic systems installed either on or within aircraft. Equipment hazards addressed include those due to indirect effects on equipment and its associated wiring that is mounted on the aircraft exterior as well as indirect effects on equipment and its associated wiring located within the aircraft interior. This document applies to new aircraft and equipment designs, modifications of existing aircraft or equipment, and applications of existing (off the shelf) equipment on new aircraft. NOTE: This ARP does not address direct effects such as burning, eroding, blasting, of aircraft structure nor does it address fuel ignition hazards (see related reading material in 2.3 of this document). This ARP does not address lightning zoning methods or lightning test requirements, methods, and techniques. Coverings (fairing, skin, cowl, etc.) should normally prevent direct attachment of the lightning channel to underlying system components. However, if a direct lightning strike attachment to a system component can occur,…
