Based on request from industry, operational evaluations have been conducted by the JAA and then by EASA since 1997. Associated OEB reports are published on the EASA website in support of Approved Training Organisations (ATO) and operators, for the aircraft, equipment and/or operations which have been evaluated in the relevant OEB reports.
With the entry into force of Commission Regulation (EU) No 69/2014 on 18 February 2014 the concept of Operational Suitability Data (OSD) was implemented, integrating operational evaluation elements into the certification design process as foreseen in the Basic Regulation.
Available operational suitability data are then referenced in the applicable Type Certificate Data Sheet (TCDS).
