scope:

The present document summarizes the rationale on which current developments of ETSI European standards (EN) for ground-based air traffic management radio equipment and constituents has been based to allocate RF-parameters either to Harmonized Standards covering essential requirements under the R&TTE Directive [i.7] or to Community Specifications as means of compliance to the essential requirements of the Interoperability Regulation [i.1] and the requirements from relevant implementing rules for interoperability.

NOTE: This rationale is consistent with the existing ETSI documents EG 201 399 [i.4] and TR 102 579 [i.5] on the development of such documents.
