At which point does the JEN.JEN9 arrival procedure begin?

The JEN.JEN9 arrival procedure begins at the GLEN ROSE VORTAC. This is the designated initial point of entry for aircraft following this standard terminal arrival route (STAR) into the airspace, ensuring that all traffic conforms to the expected flight path and procedure efficiently. The JEN.JEN9 arrival is designed to streamline arrivals into the Dallas/Fort Worth area, and starting at GLEN ROSE VORTAC allows for an organized sequence of aircraft to maintain safety and efficiency during descent and approach phases.

Each of the other potential starting points is not where the procedure officially begins, as they may relate to different STARs or airways, which could lead to confusion or potential air traffic conflicts if used incorrectly in the context of the JEN.JEN9 arrival. It's crucial for pilots and air traffic controllers to understand and utilize the correct entry points for specific arrival procedures, as it helps maintain order in the busy airspace around major airports.
