ETOPS (Extended Operations) or EDTO (Extended Diversion Time Operations) – 1 Day


ICAO Requirements for Extended Range Twin-engine Operations (ETOPS) have been in place since 1985, when they were introduced to apply an overall level of operational safety for twin-engined aeroplanes which was consistent with that of the modern three and four-engined aeroplanes then flying, to which no restrictions were applied.The course has been specifically designed to provide personnel with a thorough overview of ETOPS fundamentals, focusing on key topics and concepts.


ICAO Annex 6 Part 1 under Amendment 36. This introduced the Extended Diversion Time Operations (EDTO) regime in place of ETOPS. However since then, although the EDTO regime has been widely accepted, the term EDTO has not been universally adopted the continued use of ETOPS is explicitly allowed for in Annex 6 provided that EDTO concepts “are correctly embodied in the concerned regulation or documentation”. Given this flexibility, the term ‘ETOPS’ has been retained by the FAA and others by redefining it as an abbreviation for ‘ExTended range OPerationS’ rather than as previously ‘Extended range Twin OPerationS’. EASA currently continues to use ETOPS as originally defined and the abbreviation ‘LROPS’ (Long Range OPerationS) for extended range operation by three and four-engined aircraft.
