Final answer:
In aviation, accepting a radar handoff allows a new controller to take over guiding the aircraft using the provided data block, which includes control, tracking, and altitude information.
Step-by-step explanation:
Accepting of a radar handoff constitutes approval for aircraft to be controlled, tracked, or altitude passed in the data block. In the context of air traffic control (ATC), a radar handoff is the process by which control of an aircraft is transferred from one controller to another. Once a handoff is accepted, the receiving controller has the approval to issue instructions to the aircraft related to its heading, altitude, and speed, as indicated by the information exchanged between controllers. This ensures the aircraft is seamlessly and safely guided through different stages of its flight, avoiding potential conflicts with other aircraft.
