What does SOP stand for in air traffic control?

SOP stands for Standard Operating Procedures in air traffic control. This term refers to a set of written instructions that detail the steps to be followed in specific operations. SOPs are essential for ensuring consistency and efficiency in ATC operations, as they provide a clear framework for controllers to follow during various scenarios. Adhering to SOPs helps maintain safety standards and facilitates effective communication among air traffic controllers and other aviation personnel.

While the other choices mention important concepts in air traffic control, they do not accurately represent the acronym 'SOP'. For instance, Systematic Operational Protocol, Sector Operational Plan, and Safety and Operations Principles are not standard terminology widely recognized in ATC practices like Standard Operating Procedures. Understanding the significance of SOPs enhances one's grasp of the procedures that govern safe and effective air traffic management.
