"ETOPS (extended operations) rule for the FAA that specifies that you must be within a certain time to the nearest airport - eg 180 mins flying time for twin engined planes like the B777 or A330. This is so that if there is a serious engine issue, the pilot can safely land the plane on the remaining engine." </blockquote>
