Foreword
This Candidate Harmonized European Standard (Telecommunications series) has been produced by ETSI Technical
Committee Electromagnetic compatibility and Radio spectrum Matters (ERM).
The present document has been produced by ETSI in response to a mandate from the European Commission issued
under Council Directive 98/34/EC [7] (as amended) laying down a procedure for the provision of information in the
field of technical standards and regulations.
The present document is intended to become a Harmonized Standard, the reference of which will be published in the
Official Journal of the European Communities referencing the Council Directive on the approximation of the laws of
the Member States relating to electromagnetic compatibility ("the EMC Directive") (89/336/EEC [3] as amended) and
Directive 1999/5/EC of the European Parliament and of the Council of 9 March 1999 on radio equipment and
telecommunications terminal equipment and the mutual recognition of their conformity ("the R&TTE Directive" [2]).
The present document is part 22 of a multi-part deliverable. Full details of the entire series can be found in part 1 [1].

National transposition dates
Date of adoption of this EN: 21 November 2003
Date of latest announcement of this EN (doa): 29 February 2004
Date of latest publication of new National Standard

1 Scope
The present document, together with EN 301 489-1 [1] covers the assessment of ground base station, ground mobile
and hand-held/portable aeronautical VHF radio communications and associated ancillary equipment, in respect of
ElectroMagnetic Compatibility (EMC).
Technical specifications related to the antenna port and emissions from the enclosure port of the radio equipment
covered in this scope, are not included in the present document. Such technical specifications are found in the relevant
product standards for the effective use of the radio spectrum.
The present document also covers EMC requirements for VDL Mode 2 and VDL Mode 4 ground base station radio
equipment.
The present document specifies the applicable test conditions, performance assessment and performance criteria for
ground based aeronautical radio equipment and associated ancillary equipment.
Definitions of types of ground base station, ground mobile and hand held/portable aeronautical VHF radio
communications covered by the present document are given in annex A.
In case of differences (for instance concerning special conditions, definitions, abbreviations) between the present
document and EN 301 489-1 [1], the provisions of the present document take precedence.
The environmental classification and the emission and immunity requirements used in the present document are as
stated in EN 301 489-1 [1], except for any specific conditions included in the present document. The applicable
environments referred to in EN 301 489-1 [1] where equipment covered by the scope of the present document may be
used, shall be declared by the manufacturer.
The EMC requirements have been selected to ensure an adequate level of compatibility for apparatus within aerodrome,
en route, vehicular and hand held/portable operational environments. The levels, however, do not cover extreme cases
which may occur in any location but with a low probability of occurrence.

3 Definitions and abbreviations
3.1 Definitions
For the purposes of the present document, the terms and definitions given in EN 301 489-1 [1], clause 3 and the
following apply:
base station: aeronautical radio equipment, used in the aeronautical mobile service, for use with an external antenna
and intended for use at a fixed location
centre frequency (Fc): centre of the transmitter necessary bandwidth
integral antenna equipment: radio communications equipment with an antenna integrated into the equipment without
the use of an external connector and considered to be part of the equipment
NOTE: An integral antenna may be internal or external to the equipment. In equipment of this type, a 50 Ω RF
connection point shall be provided for test purposes.
necessary bandwidth: for a given class of emission, the width of the frequency band which is just sufficient to ensure
the transmission of information at the rate and with the quality required under specified conditions (ITU Radio
Regulations, clause 146)
occupied bandwidth: width of a frequency band such that, below the lower and above the upper frequency limits, the
mean powers emitted are each equal to a specified percentage ß/2 of the total mean power of a given emission
NOTE: Unless otherwise specified by ITU-R for the appropriate class of emission, the value of ß/2 should be
taken as 0,5 % (ITU Radio Regulations [5]).
simplex: instantaneous one-way communications link
product standard: functional standard describing frequency management parameters of radio product
operating frequency range: range(s) of continuous radio frequencies covered by the Equipment Under Test (EUT)
