It means the A/C can fly fro 330 minutes on a single engine to a diversionary airport and land safely including if needed a go around. Many of the routes the 787 is designed for are over water for long periods of time and the 330 minutes gives airlines greater flexability in flight planning with ETOPS certifications. There is more than just engines envolved though.

with 180 on twins it means you have to go more northern routes if going pacific or island hop. With 330 there is a ton more routes to fly more direct.

On behalf of several qualified, current, and REAL airline captains, thanks for your entertaining fiction. Have a good one, Transco Preacher!
