New ICAO publication (Doc 9718-2)

Doc 9718, Handbook on Radio Frequency Spectrum Requirements for Civil Aviation (Volume II — Frequency assignment planning criteria for aeronautical radio communication and navigation systems). Second Edition, 2022.


Volume II of the Handbook on Radio Frequency Spectrum Requirements for Civil Aviation presents frequency assignment planning criteria for aeronautical radio communication and navigation systems.

This material was developed in response to requests from the ICAO Regions to provide updated frequency assignment planning criteria that can be implemented on a global basis to ensure that aeronautical radio communication and navigation systems are protected from harmful interference on a uniform basis. The frequency assignment planning criteria were developed by the ICAO Aeronautical Communications Panel and the ICAO Frequency Spectrum Management Panel in cooperation with the ICAO Regional Offices.

Chapter 1 provides general principles and other material to be used in compatibility analyses of aeronautical radio communication and navigation systems. This material forms the technical basis for the frequency assignment planning criteria and can also be used when assessing compatibility of new systems planned to operate in frequency bands already used for aeronautical purposes.

Chapter 2 contains the background that was used when developing frequency assignment planning criteria for VHF airground communication systems (voice and data). This chapter gives due account to regional differences in using the VHF band while maintaining the basic principles for the protection of radio frequencies from harmful interference on the basis of globally accepted principles.

Chapters 3, 4, 5 and 6 contain the principles and guidance material for frequency assignment planning for ILS, VOR, DME and GBAS VDB, respectively.
