Simply not true. Suggest you read over AC120-42B and familiarize yourself with this AC. If you think the FAA will issue you OpSpecs for ETOPS without an approved training program you're mistaken. While it is true that the FTD can be used in lieu of a full flight sim, that is rarely done.
Also most if not all airlines use a check airman on at least the first two ETOPS legs. Who do you fly for that turn a crew lose on the N Atlantic for the first time without any line assist Remind me to avoid them in the future.
