Which ATC term refers to a directive issued for air traffic control purposes?

• A. Clearance
• B. Instruction
• C. Clear
• D. Air Traffic Control Instruction

Answer: (D)

Air Traffic Control Instruction is the formal term used for a directive issued by ATC to manage air traffic. ATC issues instructions to pilots to ensure safe separation and orderly sequencing, and these instructions cover what actions the pilot must take—such as changes in altitude, heading, or speed. A clearance is a specific type of directive that grants permission to proceed under defined conditions, but the general term for an ATC directive is the instruction. The other options are either too vague or not the standard ATC label for such directives.
