When should two-way communication be established with a control tower when approaching an airport?

Two-way communication with a control tower should be established within 15 miles of the airport to ensure safety and proper traffic management. This distance allows the pilot sufficient time to receive vital information from air traffic control, such as current runway conditions, active runways, and any traffic advisories. It also enables the controller to manage incoming and outgoing traffic effectively, maintaining a safe environment for all aircraft operating in the vicinity.

Establishing this communication early is particularly important in busy airspace where multiple aircraft may be approaching the airport simultaneously. This proactive approach helps prevent misunderstandings and potential conflicts, which can arise if pilots do not communicate their intentions clearly and in a timely manner. By adhering to this practice, pilots not only comply with established procedures but also enhance safety during their approach to land.
