Final answer:
Manual plotting of aircraft positions is not required with digitized radar systems like the ASR-11, as these systems automatically process and display aircraft data to air traffic controllers, enhancing safety and efficiency in air traffic control.
Step-by-step explanation:
The correct answer to what process is not necessary with digitized beacon and primary radar systems like the ASR-11 is that there is no need for manual plotting of aircraft positions. With digitized radar systems such as the ASR-11, information about aircraft speed, distance, and altitude is directly processed and displayed to air traffic controllers on-screen, eliminating the manual process.
Traditional radar systems required operators to manually plot and track aircraft movements based on the blips seen on the radar screen. Thanks to modern digital processing, this labor-intensive task is no longer necessary, as computers automatically calculate and display aircraft positions in real-time. This technological advancement enhances both safety and efficiency within the field of air traffic control.
In digitized beacon and primary radar systems like the ASR-11, data fusion is not necessary. Data fusion is the process of combining data from multiple sources to generate a more accurate and comprehensive picture. However, in these systems, the digitized beacon and primary radar data are already sufficient on their own to provide accurate information about aircraft positions and movements.
