The Communications section includes all items related to technical and operational aspects of Air Traffic Management (ATM) voice and data communications systems, as well as facilities, procedures and applications that support them. The section also encompasses aspects related to aviation frequency spectrum management.
What falls under Communications?
According to the Communications Panel (CP), the following areas of expertise are an integral part of Communications (ICAO, 2020):
1) The development and update of strategies and plans for aeronautical communications harmonization;
2) The consolidation and development of operational requirements for voice and data communications;
3) Monitoring of the development and implementation of ATM communication systems and facilities;
4) The development, as required, of procedures and guidance material for:
a) Air-ground and ground-ground data applications for air traffic services;
b) A performance-based framework for communications;
c) Command and Control (C2) and ATC links for Remotely Piloted Aircraft Systems (RPAS);
d) SATCOM voice;
e) Procedures to support ATM voice and data communications;
f) Items related to cybersecurity for ATM communications;
g) Infrastructure to support the items listed above.
Frequency spectrum management is also an integral part of, and closely linked to, the Communications domain, as highlighted by the Frequency Spectrum Management Panel (FSMP) (ICAO, 2020). The following aspects are included in this section:
- The advancement of technological developments and innovation, in order for aviation to efficiently manage the finite and limited frequency spectrum resource;
- Aeronautical frequency and/or spectrum management and the international process of developing the frequency spectrum as a resource;
- Aspects falling under the jurisdiction of the International Telecommunication Union (ITU) (for more info, visit http://www.itu.int);
- Matters covered by the World Radiocommunication Conferences (WRC).

COM 4.11 PRONUNCIATION OF WORDS FIVE LETTER NAMING CODES (5LNC)
Pronunciation of letters has been standardized but there is a lack of uniformity across world regarding the pronunciation of waypoints.
Specifically, these relate to the confusion over the route designator and accurate identification of the correct 5LNC.
ICARD is responsible for the allocation of these names however there are problems. Certain ICAO rules do exist over duplication of code names covered in Annex 11, Appendix 2, and Section 3.3. There are also like sounding names that are not covered by any rules.
These regulations require the:
“Name code designator shall be easily recognizable.”
Eurocontrol has already drawn up some rules requiring the following to be satisfied within 500nm:
Rule 1: No two or more waypoint shall have 4 or more identical letters
Rule 2: The last 3 letters of two or more waypoint names shall not be Identical
Rule 3: Letters 1, 2, 3 shall not be the same
Rule 4: Letters 2, 3, 4 shall not be the same
However, there are many existing waypoint pairs that do not comply with this requirement and there has been no long term study to assess the long term sustainability of the I-CARD system. The rapid increase in new routes, PBN procedures and traffic growth has contributed to the problem. We also believe that pronounceable words should be reserved for voice communicable routes.
IFATCA Policy is:
Pronounceable names should be reserved for waypoints that are used in voice communications.
