twin engined aircraft flying to cuba/barbados etc

[j4ckos mate]

with them being twin engined (757,767 a330) what route would a uk charter flight take to the dom republic or cuba?

i thought they cant be too far from land, but surely this would make the route far too long,

The route shouldn't differ from a 3 or 4-engined airliner, AFAIK, provided the aircraft meets ETOPS requirements:

Flew from Gatwick to Montego Bay last spring on a Thomson 767, we seemed to head out over the sea around Southampton, and not see land again until we arrived in the Carribean, I have not read the ETOPS link, but from memory I beleive you need to be 90 minutes away from land, and I am guessing that was what we did, although I was a little surprised at the time.

Pretty handy for this stuff.

ETOPS is 120 minutes, upped to 180 after one year of trouble free operation, with the exception of the Boeing 777 which started with 180 in the USA although not in Europe (funny that)

You're ETOPS when more than 60mins from an adequate airfield.

Most UK operators will be certified for 180 mins ETOPs. That means they can be 180 minutes at single engine speed from a suitable airfield.Single engine speed in a 757,767 is about 400kts so they must remain within 1200nm from a suitable airfield

Going to Cuba something like this.



The Dominican Republic.



These routes could vary though with wind and weather over the Atlantic.

Fill your boots.

Here's a map showing the 180 mins ETOPs area (assuming all airports are open)



If you are non ETOPS you can only go in these areas.


Note Flight to the USA Caribbean is still possible non ETOPS up over Greenland but would possibly be limited by fuel/crew etc depending on type.

In the Indian/Southern Ocean, most use four engined aircraft to get over to Africa from Oz. A340s and Jumbos. The twins have to make a large dogleg into the north of the Indian Ocean because of the lack of suitable airports. The big twins will stay up near 22 degrees south in the middle of the Indian Ocean. The Jumbos sometimes go right down to 65 degrees south. Looking at some of the routes and certain flights you can see the Jumbos getting across to Africa up to 2 hours faster because they can chase the winds(chase the least headwinds!) and the more direct route. Admittedly they don't compete with each other on city pairs.
