Mode S is being deployed within the Core Area of Europe (that area subject to high air traffic density) because current SSR systems have reached the limit of their operational capability (increasing RF pollution, lost targets, identity errors and Mode A code shortage). Mode S is therefore a necessary SSR replacement and will form part of the basis of the Surveillance infrastructure for much of the first quarter of the 21st Century.
Mode S Elementary Surveillance (ELS) is being deployed initially within the airspace of Belgium, France, Germany, Luxembourg, the Netherlands, Switzerland, Italy, the Czech Republic, Hungary and Greece. Mode S Enhanced Surveillance (EHS) is being deployed initially within the designated airspace of the United Kingdom, Germany and France, together with the airspace at and above FL 245 in the Amsterdam FIR and the airspace at and above FL 245 in Belgium and Luxembourg (subject to promulgation). The other Core Area States are expected to implement EHS in due course.
Other European States (beyond the Core Area) are also upgrading ground systems to Mode S capability, to benefit from the improved integrity of surveillance data, air picture and tracking and increased target capacity, and are expected to implement Mode S ELS or EHS at a later stage.

Each of the States participating in the Mode S programme has different timetables and requirements for Mode S implementation. An outline of each States current Mode S ELS and EHS implementation status, together with future plans, contact details, exemption policy and other relevant information can be accessed below. However, please be aware that the information provided below is designed to give an indication as to the rules and requirements of the individual states listed. The latest documents / amendments / circulars / supplements etc must be consulted so as to obtain the very latest, up-to-the-minute information.
