4.4.2. Holders of multiple endorsements

ED Decision 2023/005/R

Whenever licence holders are authorised to hold concurrently more than one unit endorsement[17] or its equivalent for AFISOs, a roster should be set up to allow for the regular exercise of the privileges. Particular attention should be paid to the definition of the number of unit endorsements that ATCOs working at the same RTC should concurrently hold and maintain. This should be determined on the basis of a thorough safety assessment as well as on the need to comply with applicable requirements (e.g. the minimum hours for the maintenance of the unit endorsement for each aerodrome concerned). Based on the information gathered from the implementation feedback and from discussions with stakeholders, current experience indicates that three concurrent unit endorsements can be held and maintained safely, in compliance with applicable requirements.

When defining the minimum hours of exercising the privileges in the context of the competence scheme, the holders of more than one unit aerodrome endorsement should not be treated differently unless the level of harmonisation of equipment and/or ATM procedures between RTMs is considered mitigating. A minimum number of hours should be retained for each unit endorsement individually and a number of hours for the overall RTM exercises as well.

Equipment may facilitate the logging of the required hours.


[17] According to AMC1 ATCO.B.020(a) to Regulation (EU) 2015/340 [5], each aerodrome for which aerodrome ATC service is provided from an RTC, should constitute its own unit endorsement.
