When do you transfer communications of an aircraft?

Transferring communications to an aircraft typically occurs before the aircraft enters the receiving controller's airspace. This process ensures that the pilot is on the appropriate frequency and is in contact with the correct controller well in advance of entering a new airspace. It allows the receiving controller to provide necessary information and instructions in a timely manner, ensuring a seamless transition for aircraft as they move from one air traffic control jurisdiction to another. This proactive approach helps maintain safety and efficiency in the airspace system, minimizing the potential for misunderstandings or communications delays.

Other scenarios, such as transferring communications after the aircraft has landed or in response to a pilot's request, can be less efficient and might not adhere to established procedures, which prioritize proactive communication transfers based on airspace boundaries. Similarly, transferring at any time during flight may not provide the structured communication framework necessary for safe air traffic management.
