A few questions on ETOPS
Good day fellow aviators.
1. From regulatory perspective, should there be at least two alternates between ETOPS entry and exit point (to get criticial point between them)? Is it allowed to have only one alternate between ETOPS entry and exit point IF it covers the whole ETOPS area of operation?
2. Could there be more then one "set" of ETOPS entry and exit points? Say in the beginning of flight and then at the end, or should it be treated as a one whole ETOPS "area"?
3. Is it allowed for route to destination alternate (normal, non-ETOPS alternate) to be ETOPS-route, or should all routes to destination alternates remain within 60 mins from suitable alternates?
