What does "descend via" mean in an approach procedure?

The phrase "descend via" in an approach procedure signifies that the pilot is authorized to descend according to the specific altitudes and restrictions outlined in the Standard Terminal Arrival Routes (STAR). This means that the aircraft can follow the predetermined vertical profile, which helps to ensure safe and efficient integration into the terminal airspace.

Following STAR altitudes allows pilots to manage their descent in a structured manner, coordinating with air traffic control and maintaining safe separation from other aircraft. By adhering to these specified altitudes, pilots can optimize their descent profile while complying with established airspace regulations. Understanding this terminology is crucial for pilots to navigate approach procedures effectively and safely.
