Channel spacing for aeronautical OPC frequencies to be converted to 8.33 kHz in 2018

Published 10.11.2017

In 2018, all aeronautical OPC (operational control) frequency assignments, the common frequencies used by aviation companies in the frequency range 131.400–131.975 MHz, will be converted to 8.33 kHz channel spacing.

Radio licences for equipment with 25 kHz channel spacing will be renewed to reflect the narrower channel spacing in the same centre frequency. Also the corresponding channel number for the 8.33 frequency will be added to the radio licence.

Licence holders are required to adjust their radio systems to meet the 8.33 kHz channel spacing requirement of their licence by the end of 2018. The adjustments need not be notified to FICORA.

Under the Commission Regulation (EU) No 1079/2012, aeronautical radio equipment operating on the VHF band (30–300 MHz) are required to have the 8.33 kHz channel spacing capability by 31 December 2017.

The European Commission granted Finland a derogation from the Commission Regulation. Under the derogation, the transitional period for the implementation of 8.33 kHz channel spacing in frequencies used by air navigation service providers in Finland is ten years. Similarly, a transitional period of ten years was granted for general aviation equipment only using 25 kHz channel spacing.

However, aviators must note that the derogation does not apply to OPC frequencies.
