Pre-takeoff checklist
So the final approach is anything north of PWK I guess that means we need visit Green Bay before we turn south for the Chicago lakefront route. I thought the "enhanced Class B" went away 6 weeks afetr 9/11 but maybe I was misinformed.
Look at the plate. You've got a remain within 10 for the procedure track. Stay outside of that and away from those altitudes (+/- 500 ft) and you're fine. Flying within 100' of a published altitude across a known final approach path is just not a good thing to do. How accurate is your altimeter?
