What is one primary role of flight progress strips in air traffic control?

One primary role of flight progress strips in air traffic control is to aid in planning for aircraft and resolving potential conflicts. Flight progress strips are physical or digital representations of flight data that provide controllers with essential information about the aircraft under their jurisdiction, such as the aircraft's identity, flight plan, altitude, and current status.

These strips allow controllers to track the movement of aircraft in real time and make necessary decisions regarding their separation and the most efficient routing to ensure safety in the airspace. By visualizing critical information at a glance, controllers can quickly identify potential conflicts, such as two aircraft on similar flight paths, and take appropriate measures to mitigate risks, ensuring safe and efficient air traffic management.
