8.33kHz
A consortium led by IAOPA Europe and aviation consultants Helios has applied for EU funds to offset the costs of upgrading equipment to meet new rules on 8.33kHz channel spacing - and they are calling on General Aviation (GA) users and aerodromes to pre-register now to obtain refunds where applicable.
Expansion of the voice channels available helps relieve congestion in the VHF band as mandated by SESAR Single European Sky. Upper airspace has already been addressed and regulatory attention is now switching to lower airspace below FL195, commonly used by the GA community. The new regulations will affect all radios operating in the 117.975-137MHz band (the VHF band) - both airborne and ground based - and come into force from 31st December 2017 also for VFR.
