Operator requirements for ETOPS
 

Hello
No strictly a technical issue but this seems to be the most appropriate forum to post .
There is a need to have an overview of the requirements that an operator needs to have in order starting conducting ETOPS under EASA ( starting with120’)
Whiile I m getting busy now into reading on the issue with not much time I thought I could ask here to maybe complement what I could find on the available documentation.
any input will be much appreciated
