Quote 'The question states AVERAGE GC = 100 this means half way which is exactly the same as the rhumb line. Remember a rhumb line is constant bearing and is also the same as average great circle.' This is true however....
From the answers given on the original question the wording is incorrect? , there is a question on the DB that gives those answers but it lists co-ordinates , its been a few months so i cant recall. Il see if i can find it.
