I was just noticing that CO uses 757s on the LIS-EWR routes and since quite a few twins fly to LIS, for example TP 310s and Air Transat 330s, I was wondering what route they would use, to keep within the 138/207 minute rules? I presume they'd route out towards the Azores and then across towards Newfoundland? Anyone know? Can anyone get their hands on a route/ flight plan?

We usually use Lisbon, Santa Maria or Lajes and Gander or goose.

TP also uses the four engine A340 on the JFK/EWR-LIS runs. Twin engine flights to Lisbon are nothing new. TP has used the A310 for a long time and TWA used to fly the 757 as well.

TWA always went near the Azores. It was pretty weird being out over the ocean and picking up the VOR off the northern edge of the Azores. Generally, that flight would go on to Barcelona. Great trip.TC

Remember 138-minute ETOPS? Supposedly that was invented to close the last gap in that existed in the North Atlantic under 120-minute rules. As long as Lajes, Gander and Keflavik are all available no point in the Atlantic north of latitude 35 degrees is more than 820 nm from an airport.

Every so often, Transatlantic flights into JFK at least, approach the airport from the south. These generally route via the Azores, I assume based on winds, weather.

You mean they use the CAMRN arrival? Or you just mean they land runway 4?

ETOPS207 is approved on a route-by-route basis over the north Pacific only.

Timz,
CAMRN arrival, landing on whatever runway was in use.

ConcordeBoy-

I believe its more than a route-by-route basis... I think its a flight-by-flight basis. May be wrong.

I was wrong about that 35-deg-latitude line in the North Atlantic-- turns out that

lat 35.94848 lon 48.76233 is 820 nm from Gander and Bermuda, and
lat 37.45680 lon 44.35652 is 820 nm from Gander and Lajes.

Also: the 138-minute rule closed the last gap in the north North Atlantic. If we consider the North Atlantic to extend all the way down to Ponta do Calcahar, then there is a small triangle that may not be covered even by 180-minute rules. Lat 24.06236 lon 42.27743 is 1172.4 nm from Lajes, Antigua and Sal.

You're correct, I failed to be specific enough. Cheers!
