So, curious about ATC radar equipment: When there is a Mode C report, does the screen adjust the blip position to reflect elevation error? Alternately, is there an average correction factored in or none at all? I can definitely see this mattering, especially close to the radar. If you're 9,500' inside a surface Bravo, you're two miles up and probably less than five miles from the radar. That gives you about a half mile of position error.
