I looked briefly at AFPEx a few years ago but started to glaze over and gave up. Besides I have only had a SD flightplan go astray once through a bodged amendment.
So I just took another look, it doesn't seem any clearer this time around.. On a cursory sweep of the website there are various guides and assistances, none of which seemed to answer the question "I am going from A to E via B,C and D, to whom who do I address the flightplan?"
Does there exists a comprehensible guide anywhere?
Of course I could always form the FP in SD and then copy their addressing
