Lidhje Dixhitale VHF ajër-tokë (VDL) pajisje radio Modeli 4; Karakteristika teknike dhe metodat e matjes për pajisjet me bazë në tokë; Pjesa 5: EN i harmonizuar që mbulon kërkesat thelbësore të artikullit 3.2 të direktivës R dhe TTE

VHF air-ground Digital Link (VDL) Mode 4 radio equipment; Technical characteristics and methods of measurement for ground-based equipment; Part 5: Harmonized EN covering the essential requirements of article 3.2 of the R&TTE Directive

Scope

The present document applies to Very High Frequency (VHF) Digital Link (VDL) Mode 4 ground-based radio
transmitters and receivers for air-ground 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 112,000 MHz to 136,975 MHz as defined in ICAO VHF Digital Link (VDL) Standards and
Recommended Practices (SARPs) [i.5].
Manufacturers should note that in future the tuning range for the ground transceivers may also cover any 25 kHz
channel from 108,000 MHz to 111,975 MHz.
The present document is intended to cover the provisions of Directive 1999/5/EC [i.3] (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 [i.3] may apply to equipment within the scope of the present
document.
NOTE: 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.
