Ready 833kHz Mandatory when flying in controlled airspace within Europe.

Tuesday 24th October 2017

Note 8.33 is mandatory in Europe as of January 2018. When flying in controlled airspace in Europe, you must have an 8.33kHz radio to meet the mandate. If you do not update to 8.33kHz you may cause interference on adjacent channels for 8.33 radio users.
You will not be able to tune to 8.33 frequencies, and so will not be able to communicate with certain ATSU.

UK CAA Comment “On 1 January 2018 the law changes and all aircraft operating in airspace that requires the carriage of a radio must have 8.33 kHz-compatible equipment fitted and operational. After this date all 25kHz radios can no longer be used, unless specifically exempted for a particular channel such as the emergency frequency 121.5MHz. This means that all General Aviation (GA) aircraft must comply with this change to UK law to maintain safe communications with ground stations.
The UK leaving the EU will not affect the implementation of this new legislation.”


The CAA has issued an approval for handheld devices that meet certain stipulations.

Pilot owners should obtain confirmation from the manufacturer that their radio meets the conditions of the Approval. Once confirmed, the pilot may then use the Equipment Approval LA301075 as the reference when applying to the CAA for their Aircraft Radio Licence, which is required by the Wireless and Telegraphy Act. We are aware of the following 8.33 kHz handheld radios that meet the specified requirements:

Yaesu FTA-550
Yaesu FTA-750
Yaesu FTA-450
This is not an exhaustive list: there may be other models that meet the requirement. Above are those currently identified to the CAA by manufacturers.
