Digital computers are being applied in large numbers to air traffic control operations in the United States. By the mid-1970's, all U.S. en route traffic control centers and all busy terminals will be equipped with systems featuring digital computers which process flight plans and radar and beacon data into displays for air traffic controllers. Work is underway to further apply computers to such control functions as ground-based conflict prediction, sequencing and spacing, and flow control.
