What are the operational altitudes typically used during the DOWNE4 Arrival?

The operational altitudes typically used during the DOWNE4 Arrival are between 3,000 and 5,000 feet. This arrival procedure is designed to transition aircraft from en-route flight down to the terminal airspace. By establishing an altitude range of 3,000 to 5,000 feet, pilots and air traffic controllers can better manage traffic and ensure safe separation from other aircraft while also preparing for the final approach to the airport.

Maintaining this altitude range allows for effective descent profiles and alignment with the other procedures associated with arrivals into busy airspace. It also helps manage the transition from higher cruising altitudes to lower approach altitudes, ensuring that the aircraft is configured correctly for landings without descending too rapidly or entering crowded airspace prematurely.

Other altitude options might reflect operational altitudes for different segments of flight or specific airspace requirements, but they do not align with the established protocols for the DOWNE4 Arrival. This altitude range plays a crucial role in the safety and efficiency of the arrival procedure.
