Lidhje Dixhitale VHF ajër-tokë (VDL) Modeli 2; Karakteristika teknike dhe metodat e matjes për pajisjet me bazë në tokë; Pjesa 3: Standard i harmonizuar që mbulon kërkesat thelbësore të artikullit 3.2 të Direktivës 2014/53/EU

VHF air-ground Digital Link (VDL) Mode 2; Technical characteristics and methods of measurement for ground-based equipment; Part 3: Harmonised Standard covering the essential requirements of article 3.2 of the Directive 2014/53/EU

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: 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 contains requirements to demonstrate that "... Radio equipment shall be so constructed that it
both effectively uses and supports the efficient use of radio spectrum in order to avoid harmful interference" [i.1].
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 Directive 2014/53/EU [i.1] as well as essential requirements under the SES
Interoperability Regulation No 552/2004 [i.5] and related implementing rules and/or essential requirements under the
EASA basic Regulation No 216/2008 [i.6] as amended by Regulation No 1108/2009 [i.7] may apply to equipment
within the scope of the present document.
