How must ZAE clear JAN arrivals?

Clearing JAN arrivals to the JAN VORTAC at the lowest center altitude available is a procedure that helps ensure that aircraft are safely and efficiently guided toward their destination. By using the VORTAC as a reference point, air traffic control can provide precise lateral and vertical guidance to arriving flights. This method allows for better traffic management, particularly in busy airspace, and minimizes the risk of conflicts with other aircraft.

When using the lowest center altitude available, it ensures that flights are descending in an organized manner while remaining within safe altitude limits and regulations. This also assists pilots in planning their descent more effectively, allowing them to adjust their altitude as necessary to manage speed and comply with air traffic control instructions smoothly.

The other options involve alternative routing measures or unclear directives that may not provide the same level of safety and control in managing arrivals to JAN. Hence, using the JAN VORTAC at the lowest available altitude remains the most straightforward and effective method of clearing flights into that airport.
