scope:

The present document applies to DSB AM ground base stations, with channel separations of 25 kHz intended for analogue speech. The scope of the present document is limited to ground based transmitters, receivers and transceivers. These radio equipment types are capable of operating in all or any part of the aeronautical frequency band between 225 MHz and 399,975 MHz.

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 as well as essential requirements under the Single European Sky Interoperability Regulation (as amended) [i.3] and related implementing rules 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.
