I've been hesitating to post because I thought someone would bring
up better information than I have, but I haven't noticed anyone post
about a Halon replacement.

I'm not sure if I have all of my facts straight but as I recall,
when my wife got a fire extinguisher for our plane she was offered
something that is a non-banned substitute for Halon. I had told
her to find a Halon extinguisher, but I forget what exactly she
ended up getting. I do recall that she was told that the other
was just as good as Halon but not banned.

I've been meaning to get out to the plane to check, but I'm trying
to finish up end-of-semester assignments. Someone else want to
jump in and correct me first?
