Radio Communication Failure Procedures

With effect from 1 May 2025, the European Union (EU) is introducing amendments to its radiocommunication failure (RCF) procedures.

The purpose of this SN is to:
•    highlight the forthcoming change of EU RCF procedures;
•    emphasise that no changes are being made to the UK’s RCF procedures;
•    notify UK air traffic services personnel that they should be alert to the possibility that international flight crews may mistakenly follow EU RCF procedures within the London and Scottish FIRs.
