IEC PAS 62396-6:2014

Process management for avionics - Atmospheric radiation effects - Part 6: Extreme space weather and potential impact on the avionics environment and electronics

IEC PAS 62396-6:2014(E) details the mechanisms and conditions that produce "extreme space weather" (ESW) and the changes within the avionics environment under such conditions. Consideration is given to the impact and risks of ESW on passengers and crew travelling on aircraft in flight and the option for in flight monitoring of the environment. Avionics electronics and systems operating during flight can be affected under such conditions and these are reviewed. By testing of complete equipment for extreme space weather tolerance, the degree of robustness to ESW can be assessed. In the PAS, flight related infrastructure (not the aircraft itself) that can be affected or disabled by an extreme space weather event is identified.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

A PAS is a technical specification not fulfilling the requirements for a standard, but made
available to the public.
The document “Extreme Space Weather: impacts on engineered systems and infrastructure”
from the Royal Academy of Engineering (United Kingdom, London) has served as a basis for
the development of this publicity available specification.
The permission from the Royal Academy of Engineering (United Kingdom, London) to include
the report within this PAS is gratefully acknowledged by the IEC.
IEC PAS 62396-6 has been processed by IEC technical committee 107: Process management
for avionics.

PROCESS MANAGEMENT FOR AVIONICS –

ATMOSPHERIC RADIATION EFFECTS –

Part 6: Extreme space weather and potential impact

on the avionics environment and electronics

1 Scope
This PAS details the mechanisms and conditions that produce “extreme space weather”
(ESW) and the changes within the avionics environment under such conditions. Consideration
is given to the impact and risks of ESW on passengers and crew travelling on aircraft in flight
and the option for in flight monitoring of the environment. Avionics electronics and systems
operating during flight can be affected under such conditions and these are reviewed. By
testing of complete equipment for extreme space weather tolerance, the degree of robustness
to ESW can be assessed. In the PAS, flight related infrastructure (not the aircraft itself) that
can be affected or disabled by an extreme space weather event is identified; such
infrastructure can be in the local “space” environment or on the ground.
This PAS is identical to the “Extreme Space Weather: impacts on engineered systems and
infrastructure” document from the Royal Academy of Engineering (United Kingdom, London)
which is included in Annex A.
2 Normative references
