Planes turn in the sky primarily because they are following air traffic control instructions and established routes.
Here's a more detailed breakdown:
Air Traffic Control (ATC)
- Following Rules: Planes must adhere to air traffic control regulations to ensure safe and efficient air travel. According to the reference, planes are turning "because they are following air traffic control rules."
- Directed Turns: Air traffic controllers frequently direct planes to turn for various reasons. This is the most common scenario.
Navigational Routes
- Departure Routes: Planes often follow pre-defined departure routes after takeoff. These routes may involve turns to guide the plane towards its destination efficiently and safely. The reference notes that turns can be due to "following published departure routes."
In summary, planes turn in the sky to comply with ATC instructions and to navigate along established routes. These turns are essential for safety, efficiency, and organization within the airspace.
