• A. 5 NM
• B. 25 NM
• C. 50 NM
• D. 15 NM

Answer: (D)

When working with ATC, you want to establish two-way communication before entering the airport’s controlled airspace so you can be properly sequenced and instructed for the approach. The AIM guidelines place initial tower contact at about 15 nautical miles from the airport. Reaching out at this distance gives you and the tower enough lead time to confirm the active runway, winds, and traffic situation, and to receive instructions for routing, altitude, and sequencing before you enter the pattern or approach. Contacting much closer can squeeze you into a busy flow without adequate guidance, while contacting much farther out isn’t typically how the tower handles initial coordination—approach or center would handle radar vectors and sequencing in those cases. So, about 15 NM out is the right balance for smooth, safe integration.
