ATC Radios and Sectors
Another day, same drill, but the controller is talking to another airplane on another frequency, so you might hear say again more than once. ATC is often tasked to use multiple frequencies at once. Its not the easiest thing to do with people talking on both, but we adapt and prioritize. One way we adapt to prioritizing is by the airplanes speed. The faster they are going, the more likely it is that I need to get to them first before they enter another controllers airspace without coordination.
