Lidhje Dixhitale VHF ajër-tokë (VDL) Modeli 2; Karakteristika teknike dhe metodat e matjes për pajisjet me bazë në tokë; Pjesa 3: EN i harmonizuar që mbulon kërkesat thelbësore të artikullit 3.2 të direktivës R dhe TTE

VHF air-ground Digital Link (VDL) Mode 2; Technical characteristics and methods of measurement for ground-based equipment; Part 3: Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive

Scope

The present document applies to VDL Mode 2 ground-air digital communications using Differential Eight Phase Shift
Keying (D8PSK), intended for channel increments of 25 kHz. The VDL Mode 2 system provides data communication
exchanges between aircraft and ground-based systems, operating in the VHF band (117,975 MHz to 137,000 MHz).
The scope of the present document is limited to ground based stations.
NOTE 1: The VDL Mode 2 can be used as an Air/Ground sub-network of the Aeronautical Telecommunication
Network (ATN) using a band with AM(R)S spectrum allocation.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.2] (R&TTE Directive), article 3.2,
which states that "... radio equipment shall be so constructed that it effectively uses the spectrum allocated to
terrestrial/space radio communications and orbital resources so as to avoid harmful interference".
In addition to the present document, other ENs that specify technical requirements in respect of essential requirements
under other parts of article 3 of the R&TTE Directive may apply to equipment within the scope of the present
document.
NOTE 2: A list of such ENs is included on the web site http://www.newapproach.org.
Compliance with relevant aviation regulations may also be required before equipment within the scope of the present
document can enter into service.
