For a northern/goliad arrival, upon reaching the Port Bay Bridge descend to what altitude and fly direct to which landmark to join the Northern Arrival to PT SHAMROCK?

• A. 500' MSL, Aransas Pass
• B. 1,000' MSL, Port Bay Bridge
• C. 1,000' MSL, Aransas Causeway
• D. 1,500' MSL, Port Aransas Causeway

Answer: (C)

The key idea is the published transition for the northern/goliad arrival into PT SHAMROCK: descend to a safe altitude on the Port Bay Bridge segment and then proceed to a visual landmark to merge with the Northern Arrival. Descending to 1,000 feet MSL and flying direct to Aransas Causeway places you on the correct intercept path to join the Northern Arrival for PT SHAMROCK, providing the proper altitude and a clear, designated cue to merge with the arrival stream. The Aransas Causeway is the specified landmark to use for this merge, which keeps you on the published track and ensures separation from other traffic. Choosing a lower altitude like 500 feet or using a different landmark (such as Aransas Pass or Port Aransas Causeway) would take you off the intended route or at an improper altitude, risking workload and sequencing issues.
