What is an "intercept vector" used for in air traffic control?

An "intercept vector" in air traffic control is primarily used to guide an aircraft onto the correct flight path for landing. When an aircraft approaches an airport, air traffic controllers may provide vectors, which are specific headings and altitudes, to ensure that the aircraft aligns properly with the runway. This guidance helps to manage the traffic flow safely and efficiently, ensuring that aircraft can land without conflicts with others or obstacles in their path.

Precision in assisting aircraft to intercept the final approach course is crucial for safety and efficiency in busy airspace. The use of intercept vectors enables controllers to adjust the flight trajectory, allowing for proper sequencing and spacing between arriving aircraft. This practice not only supports operational safety but also helps to facilitate smooth landings, especially in conditions where visual navigation may be challenging.
