Following Standardisation feedback, the Guidance Material in question has been introduced with the aim of allowing competent authorities to enter any additional licensing information deemed necessary, such as national licence endorsements and/or Radio-Telephony (R/T) licences. National licence endorsements may be issued for various reasons. They may convey additional information, according to national needs, but they are not subject to recognition at EU level. Such national licence endorsements may not limit or extend the privileges granted by the licence itself. It is important to note that they are not to be mistaken with national rating endorsements, which cannot be maintained according to Regulation (EU) 2015/340.
