I was asked a question the other day by a person who really isn't into aviation and had just returned from the states, with regards to flying over the Atlantic, which got me thinking. So here go the questions.
1. Who decides the route to take over the north Atlantic? I assume there are a few factors.
1A. Is it the airline or the aircraft that are given specific etops rules? For example can 2 different aircraft for the same airline have different rules?
2. Are there 4 tracks? 2 East and 2 West?
3. I seem to remember coming back from the Dominican Republic being on an A330 and it taking an almost direct course back to Manchester UK, can it be done or is my memory fading in its old age?
4. Routes to South America from Europe again thinking (sadly) of AF A330 which seemed on a North East Course, again can it be done on a twin? but also again it could be my memory.
Thanks in advance for any response.
Sorry if the questions seem silly, still learning.
