How would you say an arc 30 miles out from the Oak City VORTAC?

To properly define an arc 30 miles out from the Oak City VORTAC, it is essential to consider both the distance and the cardinal direction relative to the VORTAC itself. The chosen response accurately specifies both the distance ("three zero mile") and the precise direction indicating the northeast relative position to the VORTAC, creating a clear understanding of the target area in question for any flight operations. In air traffic control communication, clarity is critical to ensure pilots understand exactly where the arc is located.

The designation of "northeast" is particularly helpful because it indicates a specific quadrant of the compass, allowing pilots to visualize their position and intended flight path effectively. In ATC communication, precision in direction and distance is vital, as it promotes safety and effective navigation within the airspace system.

Other choices do not achieve the same level of clarity. Some fail to specify a direction or do so imprecisely, which could lead to confusion for pilots. Overall, the selection appropriately combines the necessary elements of distance and direction in a manner consistent with aviation terminology.
