GM1 ATS.OR.140Failure and irregularity of systems and equipment

Show the text

ATS.OR.140 is complementary to the existing requirements on reporting stemming from Regulation (EU) No 376/2014 and on the reporting arrangements that ATM/ANS providers have to establish in accordance with principles and requirements on the management system set in ATM/ANS.OR.B.005 in Annex III to Regulation (EU) 2017/373. However, the primary objective of ATS.OR.140 is the timely dissemination of information needed for the safe and efficient air traffic control service and flight information service provision (e.g. information on changes in the availability of radio navigation services). The arrangements should also support the timely issuance of NOTAMs concerning the relevant information to be disseminated, in accordance with the applicable requirements in ATM/ANS.OR.A.085 in Annex III to Regulation (EU) 2017/373.
