xinhua2, I'll bite as a little reality check is in order methinks.
Threads like this can and do lead to change. More informed decisions will be made, more stories are told and told again to bigger audiences, as a result organisations may be lobbied to effect change, eventually some bad apples are sorted out and lives saved. It may be yours
don’t fly IFR there if you aren’t going to look out the window.
That's priceless, man
You may want to elaborate, that comment as such makes you look...
It comes out quite clearly from the posts here that especially IFR pilots are concerned with VFR pilots flying in conditions they shouldn't be in (i.e. low cloud base/visibility, incidentally this is one of the main killers for VFR pilots, see "The Killing Zone" by Paul Craig) around uncontrolled aerodromes, not making themselves heard. Put that together with an IFR pilot in IMC flying an approach nearby, and you have a very unsafe situation and no way of knowing about it. That's what IFR pilots are sh!t scared about, rightly so!
Your deliberations of how many planes are in how much space are non-sensical, again it's a fact of aviation that a large part of accidents happen in the vicinity of aerodromes as there is a concentration of movements around such places, and anyhow numbers doesn't matter because one plane crashing into another is all you need for things to end in tears.
