On what route must JAN APCH clear departing aircraft?

JAN Approach is tasked with guiding departing aircraft in an organized and efficient manner once they take off. The correct answer emphasizes the importance of navigating to the JAN VORTAC (a navigational aid that helps in route guidance) before proceeding to the filed route and altitude. This clearance ensures that departing aircraft are established on a predetermined and safe flight path right after takeoff, aligning with standard procedures to prevent congestion and enhance safety within the airspace.

Routing to the JAN VORTAC provides a structured way to manage traffic and maintain separation between aircraft, especially in busy airspace. By having an initial heading or course to the VORTAC, air traffic controllers can ensure that they are directing aircraft in a coherent manner that adheres to established flight paths.

The other options do not provide the same level of safety and efficiency. For instance, routing directly to the nearest airspace or the take-off runway may not account for established flight paths and could lead to conflicts with other traffic. As for being guided by the last radar vector, this is more relevant to controlled environments where radar is continuously utilized, which isn't applicable in a non-radar context. Thus, the emphasis on directing departing aircraft to the JAN VORTAC before their filed route upholds the principles of
