Silly question..how often do you end up with 6 a side ops at MB?
I only usually go there on the weekends when I assume it's very busy and I've NEVER seen this happen. The east side gets used for circuits and the west side generally for arrivals and departures. When it gets busy a start clearance is required for circuits. Not to say that circuits don't happen on west side, generally they happen on the east. Can only assume this is also due to noise issues.
