GM1 SERA.14015 Language to be used in air-ground communication
CAA ORS9 Decision No. 1
In addition to the requirement in SERA.14015, positive consideration should be given by competent authorities to the benefits of situational awareness which could improve safety on airports and relevant surrounding airspace sectors by extending the use of the English language on some safety critical frequencies at aerodromes and relevant surrounding airspace sectors also with less than 50 000 commercial IFR movements per year, but with international traffic, and a large majority of qualified pilots with acceptable level of English. This consideration would in particular encompass:
(a) use of a single frequency for all the safety-critical operations on a runway or a set of runways;
(b) the need to and feasibility of applying the requirement for English-only communications also to communications with vehicles in order to enhance situational awareness; and
(c) where this consideration could lead to a change in current communication arrangements, it should be based on the outcome of a local safety assessment;
