GM1 Article 3a(1)
Determination of the need for the provision of air traffic services
ED Decision 2020/008/R
ELEMENTS TO DETERMINE THE NEED FOR AIR TRAFFIC SERVICES PROVISION
The determination of the need for air traffic services provision in a given area and/or aerodrome may be subject to consideration and evaluation of a great number and typology of elements, such as:
(a) a mixture of different types of air traffic with aircraft of varying speeds (conventional, jet, etc.) might necessitate the air traffic services provision, whereas a relatively greater density of traffic where only one type of operation is involved would not;
(b) meteorological conditions might have considerable effect in areas where there is a constant flow of air traffic (e.g. scheduled traffic), whereas similar or worse meteorological conditions might be relatively unimportant in an area where air traffic would be discontinued in such conditions (e.g. local visual flight rules (VFR) flights);
(c) open stretches of water, mountainous, uninhabited or desert areas might necessitate the air traffic services provision even though the frequency of operations is extremely low;
(d) the complexity of the airspace concerned; and
(e) the language(s) to be used in air-ground communications, in the case of AFIS.
