Air routes are specific paths that aircraft follow when flying from one location to another. These routes are established to ensure safe and efficient travel, taking into account factors like weather, air traffic, and geography. They can be classified into different types, such as commercial routes for passenger flights and cargo routes for transporting goods. Air traffic control plays a crucial role in managing these routes, guiding pilots to maintain safe distances from other aircraft. Additionally, air routes are often marked on navigation charts, which pilots use to navigate during their flights. This system helps streamline air travel and enhances overall safety in the skies.
