A shortage of aviation radio frequencies across Europe means that most existing frequencies are being split to reduce the gap between them, allowing the introduction of more frequencies. As a result owners of GA aircraft will need to ensure that any radios fitted can transmit and receive on both 8.33kHz and 25kHz by 1 January 2018.

To ease the transition the CAA is working on a number of initiatives:

1) Allow UK registered balloons and gliders to use certain handheld 8.33kHz transceivers.

2) Apply for EU funding to assist with the cost of radio equipage.

3) Apply for an exemption from the EC to retain a small number of dedicated 25kHz frequencies for a limited period of time after the conversion deadline of 31 December 2017.

4) Remove the need for aircraft owners to pay a regulatory fee to change a panel-mounted radio by encouraging radio manufacturers to arrange a minor modification approval.
