Spooky 2:
Maybe it's been said here before but I didn't see it. ETOPS for Tri and Quads are appicable to operations in excess of 180 minutes. This does not apply to cargo operations, just pax. Mostly in place for Polar Ops and maybe a few South Pacific routings. These Tri and Quad ETOPS do not exactly mirror Twin ETOPS so it is not a one size fits all template.
