Electromagnetic compatibility and Radio spectrum Matters (ERM); VHF air-ground and air-air Digital Link (VDL) Mode 4 radio equipment; Technical characteristics and methods of measurement for aeronautical mobile (airborne) equipment; Part 4: Point-to-point functions
The present document applies to the following radio equipment types: -Very High Frequency (VHF) Digital Link (VDL) Mode 4 aeronautical mobile (airborne) radio transmitters, transceivers and receivers for air-ground and air-air communications operating in the VHF band, using Gaussian Filtered Frequency Shift Keying (GFSK) modulation with 25 kHz channel spacing and capable of tuning to any of the 25 kHz channels from 118,000 MHz to 136,975 MHz as defined in ICAO VDL SARPs [2]. The present document provides part 4 of the technical specifications. The present document is designed to ensure that equipment certified to it will be compatible with the relevant ICAO VDL SARPs [2] and ICAO VDL4 Technical Manual [1] and with the SES 552/2004 interoperability Regulation [9]. Manufacturers should note that in future the tuning range for the transmitter may also cover any 25 kHz channel from 112,000 MHz to 117,975 MHz and the receiver(s) may cover any 25 kHz channel from 108,000 MHz to 117,975 MHz. The present document applies to "aeronautical mobile (airborne and as applicable also ground vehicles)" equipment which will hereinafter be referred to as "mobile" equipment. The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is EN 301 842 [4]. A description of the scope of the VDL Mode 4 system is provided in part 2 of EN 302 842-2 [6], clause 1. EN 302 842-1 [5] deals with tests of the physical layer, EN 302 842-2 [6] deals with core link layer functionality and EN 302 842-3 [7] with additional broadcast functionality. The present document deals with tests of the datalink layer (DLS) and the link layer sufficient to support point-to-point functionality. Note that, as described in EN 302 842-2 [6], a system supporting point-to-point functionality is required to conform to EN 302 842-1 [5], EN 302 842-2 [6] and the specification in the present document. The present document includes: -clause 2 provides references to relevant documents; -clause 3 provides general definitions, abbreviations and symbols used; -clause 4 describes the VDL Mode 4 mobile station point-to-point functions; -clause 5 provides performance specifications for the VDL Mode 4 mobile station; -clause 6 provides general design requirements; -clause 7 provides protocol tests for the point-to-point functions of the system; -annex A provides a detailed cross-reference to the relevant requirements contained in ICAO VDL4 Technical Manual [1]; -annex B provides a description of compliance with the SES 552/2004 Regulation [9]; -annex C provides a bibliography; -a document history. Note that the system can support a very wide range of functions. It is not practical to provide specific tests for all aspects of functionality. The approach used is to provide detailed tests for the core point-to-point functionality and to provide tests of those remaining requirements which, if wrongly implemented, could cause a deterioration in the service offered by other VDL Mode 4 stations.

Introduction
The present document states the technical specifications for Very High Frequency (VHF) Digital Link (VDL) Mode 4
aeronautical mobile (airborne) radio transmitters, transceivers and receivers for air-ground and air-air communications
operating in the VHF band, using Gaussian Filtered Frequency Shift Keying (GFSK) modulation with 25 kHz channel
spacing and capable of tuning to any of the 25 kHz channels from 118,000 MHz to 136,975 MHz as defined in
ICAO VDL SARPs [2].
The present document may be used to produce tests for the assessment of the performance of the equipment. The
performance of the equipment submitted for type testing should be representative of the performance of the
corresponding production model.
The present document has been written on the assumption that:
• the type test measurements will be performed only once, in an accredited test laboratory and the measurements
accepted by the various authorities in order to grant type approval;
• if equipment available on the market is required to be checked it will be tested in accordance with the methods
of measurement specified in the present document or a documented alternative approved by the certifying
authority;
• equipment comply with EN 302 842-1 [5] and EN 302 842-2 [6].
The present document also indicates VDL Mode 4 compliance with the SES 552/2004 Regulation [9].
NOTE: The present document has been produced with a view to maintaining consistency of numbering with the
equivalent standard for ground equipment (EN 301 842 [4]). Where requirements are the same, they have
been given the same number. Some new airborne requirements have been inserted between requirements
that were sequential in EN 301 842 [4]. This has led to a non-standard form of numbering for new
requirements in some places.

1 Scope
The present document applies to the following radio equipment types:
• Very High Frequency (VHF) Digital Link (VDL) Mode 4 aeronautical mobile (airborne) radio transmitters,
transceivers and receivers for air-ground and air-air communications operating in the VHF band, using
Gaussian Filtered Frequency Shift Keying (GFSK) modulation with 25 kHz channel spacing and capable of
tuning to any of the 25 kHz channels from 118,000 MHz to 136,975 MHz as defined in ICAO VDL
SARPs [2].
The present document provides part 4 of the technical specifications.
The present document is designed to ensure that equipment certified to it will be compatible with the relevant
ICAO VDL SARPs [2] and ICAO VDL4 Technical Manual [1] and with the SES 552/2004 interoperability
Regulation [9].
Manufacturers should note that in future the tuning range for the transmitter may also cover any 25 kHz channel from
112,000 MHz to 117,975 MHz and the receiver(s) may cover any 25 kHz channel from 108,000 MHz to 117,975 MHz.
The present document applies to "aeronautical mobile (airborne and as applicable also ground vehicles)" equipment
which will hereinafter be referred to as "mobile" equipment.
The scope of the present document is limited to mobile stations. The equivalent specification for ground stations is
EN 301 842 [4].
A description of the scope of the VDL Mode 4 system is provided in part 2 of EN 302 842-2 [6], clause 1.
EN 302 842-1 [5] deals with tests of the physical layer, EN 302 842-2 [6] deals with core link layer functionality and
EN 302 842-3 [7] with additional broadcast functionality. The present document deals with tests of the datalink layer
(DLS) and the link layer sufficient to support point-to-point functionality. Note that, as described in EN 302 842-2 [6], a
system supporting point-to-point functionality is required to conform to EN 302 842-1 [5], EN 302 84
