Why do some return flights take longer?

It is the rotation of the Earth that is causing the longer flight times, but not because it’s moving towards or away from the flying aircraft. It is rather due to its influence on wind patterns – the so-called high-altitude jet streams. … The strength of this is related to the speed of rotation.

Why does it take longer to fly back from Europe?

Jet streams often flow west to east at about 100 mph and at 30,000 to 38,000 feet elevation where airliners fly. These winds are caused primarily by the earth’s rotation but vary as a result of solar effects on weather. Flights are often about 20% longer if they’re opposed by winds.

Why do planes avoid flying over the Pacific?

The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.

Does it take longer to fly against the Earth’s rotation?

Actually, flying west to LA takes about an hour longer than flying the return trip, but not directly because of the earth’s rotation. Instead, the earth’s rotation affects the way the wind blows on our planet.

Why can’t a plane fly slowly and let the earth pass underneath?

Originally Answered: Why can’t a plane fly slowly and let the Earth pass underneath? This is because the atmosphere is moving with the earth. For the plane to fly slowly and let the earth pass underneath, it would have exit the atmosphere in space.

Why do flights from East to West take longer?

The reason it took so much longer to fly back is the jet stream, a river of fast-moving air high up in the sky. Jet streams are usually about 100 miles wide. … Jet streams generally blow from the west to the east around the Earth, often following a meandering, curved path just like a river on land.

Why don’t planes fly straight across the Atlantic?

The reason for this is that the earth revolves on its axis, forcing the middle to bulge out slightly. The curvature of the earth and its extra equatorial width mean that curving towards the poles is a shorter distance than flying in a straight line.

Do planes fly over Everest?

Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet. However, most commercial airplanes can fly at 30,000 feet.”

Can a Boeing 777 fly on one engine?

Wide-body aircraft like the Boeing 777 are rated to fly for more than five hours on a single engine. Visit the Business section of Insider for more stories.

What happens if a plane engine fails over the ocean?

If an engine fails mid-flight, the plane will not be able to maintain its altitude but it will safely continue flying. … The Boeing continued to fly for more than 3 hours on one engine over the Pacific Ocean, before landing in Kona, Hawaii. Every commercial airplane is able to safely land on one engine.

Why don’t we fly off the earth if it’s spinning?

Normally, humans aren’t thrown off the moving Earth because gravity is holding us down. However, because we are rotating with the Earth, a ‘centrifugal force’ pushes us outwards from the centre of the planet. If this centrifugal force were bigger than the force of gravity, then we would be thrown into space.

Why do planes look like they’re not moving?

Clouds move or change shape. Our eye muscles are not good at keeping a steady gaze. As result our own movement adds or subtracts to perceived speed of the plane. A similar problem is statues seemingly moving or nodding at believers.

Do airplanes have keys?

So, Do Airplanes Have Keys? Some smaller aircraft, including the Cessna, have ignition keys that are needed to start the engine, while many larger planes do not use keys. As a general rule, larger commercial planes typically do not have keys.

Do planes have to compensate for Earth’s curvature?

There is no adjustment needed as the aircraft will naturally follow the curvature of the earth without any input from the pilot. This is because the aircraft flies through the atmosphere which also follows the curvature of the earth. There isn’t an adjustment for altitude.

Why is it faster to fly east?

The reason for quicker flights while flying eastwards are jet streams. Put simply, they are fast-flowing, narrow air currents in the atmosphere found at high altitudes.

Do planes only fly in one direction?

The jet stream always blows in the same direction because of the Earth’s rotation. Warm air from the equator rises and moves north or south towards colder regions.
