What authority does EODO provide regarding airport operations?

The correct choice indicates that EODO provides a comprehensive range of authorities regarding airport operations, which includes all aspects mentioned in the options.

Secondly, the authority to approach without reporting allows for smoother operation within controlled airspace, which is vital for operational efficiency. This can help reduce congestion and streamline the process for pilots and air traffic control during busy periods.

Lastly, operational planning for runways is critical, as it entails addressing factors like runway usage, timing, and maintenance schedules to ensure optimal safety and efficiency in airport operations. This planning is essential in managing the logistics of aircraft landings, takeoffs, and overall air traffic management.

Combining these functions emphasizes that EODO provides a broad spectrum of authority that is indispensable for managing and facilitating effective airport operations. Thus, when considering the variety of responsibilities associated with airport operations, the answer encompasses all these critical aspects.
