Let's go on.
Like many others I am following thread interested, because many times I flew, as a tourist and working in Brazil, and I am very well impressed with that country, airports and people. And I just registered to say one thing. Someone said americans is cleared to FL 370 at 3:11 pm by Sao José dos Campos, and he showed clearly that american plane was not and showed that american plane did not understand names of the cities and airport. Legacy were unable to acknowledge and confirm Pozos de Caldas, and I know that it is a difficult city name to pronounce. American plane also didn’t understand the name of Manaus airport.
Why is difficult for people here to understand that Americans misunderstood clearance? Why PPrune member repeat clearance rules that all understand. OK, americans thought they had a clearance but he had not, this is a fact, planes collided, what more must said? Let’s go on, stop repeating the same rules, because I like to reach the end of this history.
