ICAO Standards Development
In Oct 2018, the ICAO Communications Panel approved a global implementation of SELCAL 32 ground stations for 30 Nov 2022. This will now go to the ICAO Air Navigation Commission in 2019 for ratification.
Aviation Equipment Standards Work
Both the Airline Electronic Engineering Committee (AEEC), and Radio Technical Commission for Aeronautics (RTCA) standards for SELCAL avionics were completed in 2016. The SELCAL 32 proposal is now in final approval process by the ICAO Communications Panel (CP) for inclusion in ICAO’s Standards and Recommended Practices (SARPs). During its October 2016 meeting, the ICAO CP proposed a regional implementation to ensure all FIRs are updated in a coordinated manner.
