Which TWY runs along the most western side of the airport?

The correct choice indicates that TWY Z runs along the most western side of O'Hare Airport. This taxiway is significant because it lies at the outer edge of the airfield, providing access to certain runways and terminals while ensuring optimal movement of aircraft. Understanding the layout of the taxiways, especially their locations relative to the runways and terminals, is crucial for effective aircraft movement and operational safety. TWY Z, in particular, is designed to handle traffic efficiently on the west side of the airport, which is essential for minimizing congestion and enhancing overall airport capacity.

The other taxiways are positioned more centrally or on the eastern side of the airport, which can lead to confusion about their roles and locations if one is not well-versed in the airport's layout. Recognizing which taxiway is located at the westernmost part helps in comprehending the structure of taxi routes and their functions in everyday airport operations.
