What is the width of a LF/MF airway?

The width of a LF/MF airway is defined in a way that allows for safe navigation and separation from other airspace users. The correct answer indicates that the airway is 4.34 nautical miles wide on each side for a certain distance, specifically up to 49.66 nautical miles from the centerline. Beyond this distance, the width of the airway begins to increase by a 5° splay, creating a broader navigational corridor. This design accommodates the natural dispersion of aircraft during flight and provides additional safety margins.

Understanding the dimensions of airways is crucial for pilots, particularly for navigation and compliance with air traffic control regulations. Knowledge of the airway structure helps in effective planning and execution of flights, ensuring adherence to separation standards and enhancing overall safety in the airspace.

The other options provide widths that do not align with the established regulatory parameters for LF/MF airways, either offering measurements that are too wide or too narrow, which would not provide the necessary operational safety margins required for handling traffic in controlled airspace.
