Introduction The International Telecommunication Union (ITU) started in 1992 to convene its World Radiocommunication Conferences every 3 years ICAO Special Communications/Operations Divisional Meeting 1995 recognized the importance to keep up with the rapid developments in telecommunications and it was recommended that an ICAO radio frequency handbook be developed and maintained RF handbook contains ICAO policy statements relevant to the aviation requirements for radio frequency spectrum, as approved by ICAO Council ICAO Radio Spectrum Seminar MID Office, Cairo, 4 – 6 June 2006

Organization of the handbook Chapter 1 - introduces the subject of radio frequency spectrum management; Chapter 2 - defines the objectives and purpose of the document; Chapters 3 to 5 - describe the institutional aspects and the relationships between the main participants (ITU, ICAO, national authorities, etc.); Chapter 6 - contains an overview of the spectrum management process; ICAO Radio Spectrum Seminar MID Office, Cairo, 4 – 6 June 2006

Action by Contracting States States are requested to: use the material in this policy document, as it is necessary and opportune, in their national discussions on matters relating to the use of the radio frequency spectrum by international civil aviation. In particular, the statements of ICAO policy should be incorporated in proposals from States and utilized in their preparations for ITU WRCs as the up-to-date agreement within ICAO on the reference subject.

328.6 – 335.4 MHz ICAO Radio Spectrum Seminar MID Office, Cairo, 4 – 6 June 2006

328.6 – 335.4 MHz AVIATION USE: Footnote 5.258 limits the use of this band to ILS glide path. Frequencies are used at a spacing of 150 kHz (Annex 10, Volume I, Chapter 3, 3.1.6.1) and are paired with those of the ILS localizer (see Figure 7-8 in the section on 108–117.975 MHz). COMMENTARY: ICAO policy for the future need and use of this allocation is described in detail in the general policy for the use of ILS (see ILS localizer at 108–117.975 MHz). Use of the band by other services - Footnote 5.259 was inserted by the ITU WARC‑87. ICAO Radio Spectrum Seminar MID Office, Cairo, 4 – 6 June 2006
