3.2 Single mode of operation

The single mode of operation refers to the provision of ATS to one aerodrome at a time, from a single remote tower module (RTM). Operational applications which typically would fall under the remit of the single mode of operation include, but are not limited to the provision of ATS: to one aerodrome from one RTM; during planned or unplanned contingency situations, as a dedicated backup solution for an existing aerodrome ATS; and to distant or visually blocked areas of an aerodrome, for which the view from the conventional tower cabin is inadequate or non-existent, by implementing visual surveillance system elements at the conventional tower. This could therefore be in lieu of building a second aerodrome/conventional tower. Note: With regard to the definitions in Chapter 2Error! Reference source not found., this application is not regarded as a ‘remote tower’ and therefore it falls within the scope of a ‘conventional tower’. However, the guidance in this document may be used as relevant for the visual surveillance system elements, and the relevant parts of GM3 ATCO.D.060(c) to Regulation (EU) 2015/340 may be used for the local unit endorsement course.
