Report into the Frequency of Breakdowns in Co-ordination Between Australian Air Traffic and Indonesian Services


During 1992 and 1993 there was an increase in the frequency of reported occurrences involving co-ordination between Australian and Indonesian ATS. Although some involved aircraft travelling from Australia to Indonesia, the majority (92%) involved aircraft travelling from Indonesian airspace into the Australian FIR.

The CAA Australia and the Indonesia Directorate General of Air Communications are signatories on a LOA between the two countries. This LOA supplements ICAO documents in respect to separation standards and co-ordination procedures and is - updated periodically. The latest update was on 18 December 1993 (see Appendix 1)-

The CAA have sent a series of delegations to Indonesia to liaise with their ATS authorities. These visits have included several briefing sessions to all levels of Indonesian ATS from the Director Aviation Safety to operational controllers. Specific attention has been paid to boundary conflict situations and the importance of correct and timely co-ordination, all of which are covered in the LOA. In August 1992, a major visit to the Indonesia was undertaken by CAA staff which resulted in 16 recokendations and 10 observations (see Appendix 2). These were accepted by the Indonesian authorities. In December 1993 another visit took place involving CAA supervisory field staff, managers and representatives of the CAA Quality Assurance section.
