Yes, and we are currently in the Discussion phase. When I have some time I'll try to get a proposal up on the wiki with the goal of moving things towards the Documentation phase. I've never made a proposal before so I need to figure that out. I also want to read over all the ideas thrown out in this thread first. If anyone else feels motivated and beats me to it that's fine too. As mentioned before there already is a general importance tag proposal. Moving that one along would certainly enable airports to be rendered at different zoom levels. An airport specific tagging scheme may be desirable too though. It may be useful for a future renderer to show more detailed information about airports. Zeke
