What is the dividing line between Gander and Shanwick Oceanic control areas?

The dividing line between Gander and Shanwick Oceanic control areas is established at 30 degrees West longitude. This demarcation enables efficient air traffic management between the two control regions, which are crucial for both transatlantic flights and safety in oceanic airspace. By having a clearly defined boundary, air traffic controllers can coordinate departures, arrivals, and en route aircraft to ensure safe and orderly operation in the busy airspace over the Atlantic Ocean.

The other longitudes, such as 45W, 60W, and 75W, do not correspond to the actual dividing line and would not effectively serve the operational requirements needed for control areas as they fall outside the established jurisdictional boundaries for Gander and Shanwick. Understanding these boundaries is essential for pilots and air traffic controllers alike to navigate and communicate effectively across the oceanic sectors.
