During a visual approach, when should the pilot be advised to switch frequencies?

The appropriate time for a pilot to switch frequencies during a visual approach is typically around 5 miles from the airport. This timing allows pilots to maintain communication with the appropriate air traffic control (ATC) facilities as they descend and align for landing. During this phase, pilots have visual references to navigate while ensuring they are following any last-minute instructions or clearances from ATC.

Switching frequencies at this distance also helps to ensure a smoother transition into the final approach segment and allows for any adjustments based on current traffic conditions or runway information. It is essential for pilots to remain informed about any changes in the flight environment and to communicate effectively with the controlling tower, which is why 5 miles is usually the standard recommendation for making the frequency change.

In contrast, switching frequencies immediately after takeoff might not provide the necessary situational awareness as pilots are still establishing their flight path. Switching upon entering the final approach path could be too late, as the pilots already need to be in contact with the tower to receive landing clearance and instructions. Switching when instructed by the tower, while critical, is less about timing and more about following ATC directives, which may not always align with the most efficient or standard practices for frequency changes during visual approaches.
