Why Are Flight Paths Not Straight? The Curvature of Earth and Other Factors

:earth_americas:The curvature of the Earth affects flight paths, as the shortest distance between two points on a sphere is not a straight line on a flat map.

:airplane:Safety is a primary concern for airlines, and flight paths are chosen to maximize the number of airports for emergency landings.

Why do flight paths seem curved on a map?

—Flight paths may appear curved on a flat map due to the curvature of the Earth. The shortest distance between two points on a sphere is not a straight line on a two-dimensional surface.

Why do planes avoid flying over the Pacific Ocean?

—Planes may avoid flying over the Pacific Ocean for multiple reasons. Safety concerns, lack of airports for emergency landings, and the presence of storms or turbulence are factors that influence flight paths.

Do flight paths change depending on the weather?

—Yes, flight paths can change depending on weather conditions. Pilots may alter their routes to avoid storms, turbulence, strong winds, or other adverse weather conditions for passenger safety and comfort.

What are jet streams and how do they affect flight paths?

—Jet streams are high-altitude air currents that flow from west to east. They can either speed up or slow down planes depending on their direction. Flight paths are sometimes adjusted to take advantage of these wind currents for faster travel.

Why is time-saving important in determining flight paths?

—Time-saving is crucial for airlines to maintain efficiency and profitability. Flight paths are designed to minimize travel time, allowing passengers to reach their destinations as quickly as possible.
