When the active runway is 14 at KNSE, which direction should aircraft fill the primary run-up area?

When the active runway is 14 at Naval Air Station Whiting Field, the aircraft should fill the primary run-up area from west to east. This orientation aligns with the direction of the runway, which is oriented toward 140 degrees, meaning the takeoff and landing traffic is headed primarily toward the southeast.

Filling the run-up area in this direction allows departing aircraft to efficiently transition onto the runway while maintaining proper separation and safety protocols with other operations in the vicinity. It ensures that aircraft are properly configured and ready for takeoff in a manner that minimizes the potential for conflicts with other aircraft movements.

In this case, the other directions would not facilitate efficient movement onto the active runway, as they would either align the aircraft in an undesirable position or introduce unnecessary complications in traffic flow. Thus, the correct choice enhances operational safety and efficiency at the air station.
