GM4 21.A.15(d) Application ED Decision 2021/001/R SCOPE OF OPERATIONAL SUITABILITY DATA In the application for the approval of operational suitability data, the TC applicant may apply for the approval of different types of operations. If the aircraft is certified for certain types of operations (e.g. ETOPS, RNP, LVO), the impact on the OSD constituents of [21.A.15](#_DxCrossRefBm1649096854)(d) should be addressed. The five defined OSD constituents are listed in paragraph (2)(k) of [Article 1](#_DxCrossRefBm1649096842) of [Regulation (EU) No 748/2012](https://eur-lex.europa.eu/legal-content/EN/TXT/?uri=CELEX%3A32012R0748&qid=1706006396226). As explained in [GM No 1 to 21.A.15(d)](#_DxCrossRefBm1649096986), they may not all be applicable to all aircraft types. The content of each OSD constituent is defined in the relevant certification specification (CS) and will be approved under a type certificate (TC), supplemental type certificate (STC) or change to those certificates. As explained in [GM No 3 to 21.A.15(d)](#_DxCrossRefBm1649096988), each OSD constituent can have a part that is mandatory for the end user (operator, training organisation, etc.) and a part that is not mandatory (recommendation) for the end user. However, both the mandatory and the non‑mandatory part together are the OSD constituent. Furthermore, the OSD constituent always includes the element required from the TC/STC applicant, as specified in the CS, and may include additional elements at the request of the TC/STC applicant, but still as defined in the CS. ##### GM4 21.A.15(d) Application *ED Decision 2021/001/R* SCOPE OF OPERATIONAL SUITABILITY DATA In the application for the approval of operational suitability data, the TC applicant may apply for the approval of different types of operations.
