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.

applicable technical characteristics of AIS SAR airborne equipment included in
Recommendation ITU-R M.1371 and takes into account the ITU Radio Regulations, where
applicable.
This document also specifies the minimum requirements for the interfaces to other equipment
suitable to be used as means of input and display data.
Attention is drawn on that other requirements specific for airborne equipment can exist and
are beyond the scope of this document.

4 General requirements
4.1 General
4.1.1 Overview
Requirements contained in Clause 4 are requirements not taken up in other clauses and are
verified by observation and inspection of documented evidence.
This document specifies the requirements for the AIS SAR airborne station. The AIS SAR
airborne station shall support search and rescue operations involving SAR aircraft.
4.1.2 Capabilities of the AIS
The AIS SAR airborne station shall be capable of providing to ships, and to competent
authorities, information from the SAR aircraft, automatically and with the required accuracy
and frequency, to facilitate accurate tracking. Transmission of the data shall be with the
minimum involvement of personnel.
4.1.3 Transmitter shutdown procedure
An automatic transmitter hardware shutdown procedure and indication shall be provided in
case a transmitter continues to transmit for more than 2 s. This shutdown procedure shall be
independent of software control.
4.2 Modes of operation
The system shall be capable of operating in a number of modes:
1) an "autonomous and continuous" mode for operation in all areas; this mode shall be
capable of being switched to/from one of the following alternate modes by a competent
authority;
2) an "assigned" mode for operation in an area subject to a competent authority responsible
for traffic monitoring such that the data transmission interval and/or time slots may be set
remotely by that authority;
3) a "polling" or controlled mode where the data transfer occurs in response to interrogation
from a ship or competent authority;
4) a "receive only" mode where the station does not transmit.
5 Performance requirements
5.1 Composition
The AIS SAR airborne station shall comprise (see Annex A):
1) a communication processor, capable of operating over a range of maritime frequencies,
with an appropriate channel selecting and switching method;
2) at least one transmitter and two TDMA receiving processes;

resolution of one ten thousandth of a minute of arc and uses the WGS 84 datum; an
interface (see 6.6.2) may be provided to input the position used for navigation;
4) a means to automatically input data from other sensors meeting the provisions as
specified in 5.5.1 2) may be provided;
5) a means of error checking the transmitted and received data (see Clause 6); and
6) built-in test equipment (BITE) as specified i
