It is an interesting point re: FIS & RIS. Everytime I request RIS from my local LARS they always ask me to confirm that this is indeed the service I require. I assume the reason for this is that they tend to furnish FIS aircraft with details regarding any other conflicting aircraft they are aware of (even without alt info) which lead me to my inclusion of FIS in my initial question.
Although I am well aware of the legalities of collision avoidance responsibilty (with all the services), it *can* create a false atmosphere of safety when you're regularly recieving traffic info whilst only receiving a FIS. Wonder if anyone else has experienced this also?
