En Route Control

En Route Control is a phase of air traffic management where aircraft are monitored and directed during their flight between airports, typically once they are in the cruise phase. Air traffic controllers track aircraft to ensure safe separation, provide navigation guidance, and handle any changes in route or altitude due to weather or other factors. This control segment helps maintain an organized flow of traffic across busy airspace, ensuring flights operate efficiently and safely from the moment they leave the departure airport until they arrive at their destination's approach phase.
