Under standard FAA and international ICAO procedures, a pilot should typically make initial contact with the Control Tower (Local Control) approximately 10 to 15 miles out from the airport. However, at towered airports, you are usually handed over to the Tower by an Approach Controller at a much closer distance—often between 5 and 7 miles from the runway, just before the "Final Approach Fix." If you are flying VFR (Visual Flight Rules) into a Class D airport without an approach controller, you are legally required to establish two-way radio communication at least 10 nautical miles from the field. In 2026, many busy hubs use "Data Link" (CPDLC) for these handoffs, reducing voice congestion, but the physical 10-mile "reporting point" remains the gold standard for pilot-tower coordination.
