Long-distance aircraft typically choose to fly in the lower part of the stratosphere for several reasons:
1. Fuel Efficiency: The lower part of the stratosphere offers less air resistance and lower atmospheric density compared to lower altitudes. This allows aircraft to fly more efficiently, reducing fuel consumption and increasing range.
2. Reduced Turbulence: The stratosphere is generally less turbulent compared to lower altitudes, which provides a smoother and more comfortable flight experience for passengers. This also helps to minimize stress on the aircraft structure.
3. Avoiding Weather Systems: By flying in the stratosphere, aircraft can often avoid adverse weather conditions such as thunderstorms, heavy winds, and icing that are more common in the troposphere (lower atmosphere). This helps ensure a safer and more reliable flight.
4. Jet Stream Utilization: The stratosphere is where the jet streams, high-altitude air currents, are located. These jet streams can provide a significant tailwind for aircraft flying in the same direction, allowing them to achieve higher ground speeds and reduce travel time.
5. Reduced Air Traffic: Flying in the lower part of the stratosphere allows long-distance aircraft to operate above most commercial air traffic, which is concentrated in the lower altitudes. This helps to reduce congestion and allows for more efficient routing and air traffic management.
Overall, flying in the lower part of the stratosphere offers a combination of fuel efficiency, reduced turbulence, avoidance of adverse weather, utilization of jet streams, and reduced air traffic, making it the preferred choice for long-distance flights.
