Ok, I'm stuck. I was wondering where do I find the ETOPS alternates for NAT routes, or how do I figure out which airports to use? I read the DVA Flight Sim Encyclopedia, but couldn't find it. I also checked the POM for the T7, 767 etc and haven't found it either. Some help here please. Thanks

There have been some changes recently, most significantly the FAA's shift to Extend Range Operations which requires all aircraft over 180 minutes from an alternate to meet similar requirements. You can read more about that here: http://www.flightsafety.org/asw/mar07/asw_mar07_p12-16.pdf and directly from the FAA: http://www.faa.gov/other_visit/aviation_industry/airline_operators/airline_safety/info/all_infos/media/2007/info07004.pdf
But based on the old rules:
For the 767, which is 180 minutes ETOPS certified, your route planning must never take you further than 180 minutes at single engine cruise speed from a suitable enroute alternate airport, which is defined as follows:
• Key Airport Provisions
?Must be certificated under FAR Part 139, or meet equivalent criteria
if outside FAA jurisdiction
?Must be suitable to safely operate the aircraft, i.e., runway of
sufficient length, width and strength (ref FAR Part 121)
?Must have minimum of ARFF Index A (FAA) or Category 4 (ICAO)
response capability within 30 minutes
?Must have field reporting conditions (NOTAMS), Hourly weather
reporting (METARS) and an instrument approach other than GPS.
?Airport must be available but does not need to be continuously open
(plan in place to reopen key airport services in case of aircraft
emergency)
So when planning your route in a B763, you would need to plan on 350 kts single engine cruise to an alternate in less than 180 minutes. And you would need to consider the event of depressurization, whereby you would have to consider a 2 engine cruise at 10,000 feet (~315 kts, but I'm not certain on this). This latter case is usually limiting in terms of fuel planning and if I recall the speed correctly, route planning as well.
For the 777, 207 (8?) minute ETOPS is the current certification I believe, but I'm unaware of the speeds. Otherwise, the planning requirements are the same.
