ETOPS
ETOPS, who has to approve and why? Definition. Emphasis on nil winds and single engine cruise speeds. He kept hinting on what are the environmental factors that are affecting.
6.1 Procedure for seeking approval for ETOPS
Any operator requesting approval for extended range operations with twin engine aeroplanes should submit the request with the supporting data to the Regional Airworthiness office of DGCA at least three months prior to the proposed start of extended range operation with the specific airframe/engine combination. Each operator requesting approval to conduct extended range operations should have operational in service experience as given in para 4 appropriate to the operation proposed. This data shall include the details of compliance of modifications,
additions and changes in the maintenance practices, which were made to qualify the
aeroplane system for ETOPS operations. It should also be shown that an acceptable level of propulsion system reliability has been achieved in service by the world fleet for that particular airframe-engine combination. The operator must obtain sufficient maintenance and operations familiarity with the particular airframe engine combination in question before seeking approval. Each applicant/operator for extended range approval should show that the particular airframe/engine combination is sufficiently reliable. Systems required for extended range operations should be shown by the operator to be continuously maintained and operated at
levels of reliability appropriate for intended operation
Extended Range Operations approval of an aeroplane by the manufacturer/Regulatory Authority of the country of manufacture is normally reflected by a statement in the approved Aeroplane Flight Manual (AFM) / Type Certificate Data Sheet (TDS) or Supplemental Type Certificate(STC), which specifies the Configuration, Maintenance and Procedures (CMP) Standard requirements for suitability. The CMP standards shall be of latest revision. The
standards and its revisions may require priority actions to be implemented before the next ETOP flight and other actions to be implemented according to a schedule acceptable to DGCA.
