Folks,
MAF is a highly respected outfit that provides services throughout many countries in the third world, particularly Africa, I don't really understand why some of the dills on pprune would want to stick it to them.
As for "charter" etc., just let us say that the further you are from Head Office, the more "appropriate" are the interpretations of the "regulations".
Indeed, there is a Chinese proverb that very roughly translates as: The sky is blue, the sun is shining and we are a long way from Beijing.
Tootle pip!!
