GM1 to AMC1 ATCO.B.020(a) Unit endorsements

There might be cases where, for a given aerodrome, air traffic control service is provided from a ‘conventional tower’ (defined in EASA ‘Guidance Material on remote aerodrome air traffic services’ — Issue 2) during certain time periods and from a ‘remote tower’ (defined in the EASA ‘Guidance Material on remote aerodrome air traffic services’ — Issue 2) at other times. In such cases, the unit endorsement(s) should indicate the working position(s) (conventional and/or remote tower) from which the licence holder is authorised to provide the service. NOTE: This does not refer to contingency arrangements/contingency facilities, as the related training and use are deemed to be covered by any unit endorsement. When this is done on a temporary basis for shorter/limited time periods, e.g. during a validation or for transitional purposes, different unit endorsements for conventional and remote tower may not be considered necessary.
