When clearing arrivals at the RINKY intersection, at or above what altitude should it occur?

When clearing arrivals at the RINKY intersection, it is important to ensure that aircraft are sequenced and handled safely in relation to their altitude. The correct altitude for clearing these arrivals is 13,000 feet. This altitude is established to provide a safe vertical separation between different flight levels, especially as aircraft transition through busy airspace.

Clearing at this altitude ensures compliance with traffic regulations and maintains safe distance standards between arrivals and departures. Additionally, 13,000 feet accommodates airspace restrictions, terrain elevation, and operational requirements for surrounding airports. This altitude is also likely aligned with standard arrival procedures or air traffic control protocols, which dictate when an aircraft should be cleared based on their altitude for approach to ensure a smooth and efficient flow of traffic.

In contrast, the other altitude options do not meet the required standards for safe traffic management and may increase the risk of altitude conflicts or complicate air traffic flow. Thus, the decision to clear arrivals at or above 13,000 feet strikes an effective balance between safety and operational efficiency.
