I wonder if the NAS in places like BUD might actually change the balance of power a bit. When (say) you are coming up from the south to overfly and join crosswind for 32 but some super professional expert is doing a downwind takeoff to save their esteemed employer a couple of dollars. You are requested (read told) to remain to west until they finish their interesting little circuit busting manouver. When they things like this, it must be really reassurring to know that they have TCAS and everyone is obliged to use their radio. Now, wouldn't that mess up things if there could be someone around in that G airspace, joining at 45 degrees on downwind for 32, without a radio or a transponder. But then again, that could be happening already..... Might be worth at least considering going round the same way as everybody else then.
