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.

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.

The present document applies to X-band radar sensors intended for the surveillance of airport surface movement traffic with the following characteristics:
- Utilizing modulated or unmodulated pulses.
- Transmitter Peak Envelope Power up to 100 kW.
- The transceiver-antenna connection is using a hollow metallic rectangular waveguide.
- The antenna is rotating, waveguide- based and passive.
- At the transceiver output an RF-circulator is used.
The present document covers only the essential requirements of article 3.2 of the R&TTE Directive [i.1]. NOTE 1: Since transceiver and antenna are hollow metallic rectangular waveguide based the frequency range for measurements that needs to be addressed covers 6,56 GHz to 26 GHz The lower limit of this frequency range is obtained as cut-off frequency of the combination of WR112/R84 taper section and a WR90/R100 Waveguide IEC 60153-2 [i.3]. The upper limit corresponds to the upper limit stated in ERC/Recommendation 74-01 [i.5]. NOTE 2: Since at the transceiver output an RF circulator is used, it is assumed that the transceiver characteristics
remain independent from the antenna. NOTE 3: According Article 5 of the ITU Radio Regulations [i.6] the band 9 000 MHz to 9 200 MHz is allocated to the Aeronautical Radionavigation Service on a primary basis and the band 9 300 MHz to 9 500 MHz is allocated to the Aeronautical Radionavigation Service on a secondary basis.
