Radio-telephony — I cannot find any provisions in Regulation (EU) 2015/340 requiring ATCOs to hold a radio-telephony certificate in order to be able to provide Air Traffic Services (ATS). There is also nothing on this in the licence form.
There are no requirements in Regulation (EU) 2015/340 for a radio-telephony licence. These requirements stem from the International Telecommunication Union (ITU) and are dealt with at national level. However, in accordance with GM1 ATCO.AR.D.001(c), there is the possibility for the competent authority to include the radio-telephony licence in point XIII of the licence format, if they so wish.
