Why do airplanes take longer routes?

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 do flights take longer one way than the other?

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 are flight routes not straight?

Answer: It is shorter to fly the Great Circle route than a straight line due to the circumference of the earth being so much greater at the equator than near the poles.

Why do planes not fly 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.

Why is it longer to fly east to west?

The jet stream is the real reason your flight time varies depending on the direction of your destination. Jet streams are air currents that happen at very high altitudes, including those which planes frequently fly in. … These jet streams tend to move in a wavy pattern from west to east, aided by the earth’s rotation.

Is it faster to fly with the rotation of the earth?

First, as the Earth itself rotates, it takes the air with it (thanks, gravity!). That includes the air through which planes fly. At the equator, the Earth spins about twice as fast as a commercial jet can fly. That rate slows the closer you get to the poles, but regardless, it’s always going to be faster than a plane.

How fast do planes actually go?

How fast do commercial passenger jets fly? A typical commercial passenger jet cruises at a speed of about 400 – 500 knots which is around 460 – 575 mph. Generally speaking, the higher the aircraft flies, the faster it can travel.

Is flying over Antarctica illegal?

Antarctica flights theoretically possible but rarely done

Historically, flying close to or over the South Pole was ruled out by Extended-range Twin-engine Operational Performance Standards rules. ETOPS governs how far away twin-engine jets can fly from an airport they can land at.

What is the shortest flight in the world?

The record holder for the world’s shortest commercial flight is scheduled for just 90 seconds. In good conditions, Loganair’s 1.7-mile jaunt between the Scottish islands of Westray (population: 640) and Papa Westray (population: 72) in the Orkneys, off the north coast of the mainland, can take under a minute.

Why do pilots say heavy?

When a pilot uses the phrase “heavy,” he is reminding ATC that his aircraft is large and requires more separation between it and the aircraft following.

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.”

Is it safe to fly over the ocean?

Can a plane land on water in case of an emergency? Yes it can, but it is not designed to do so, and an emergency landing is always better on land at an airport. … However, as long as sea conditions are smooth and the ditching is performed in a proper way, an aircraft can land on the sea and remain afloat.

Why are flights shorter going east?

Shorter flights

Since the jet streams flow from the west to east, they make one leg of the journey much faster (when flying with the stream) and one slower (against the stream). … Even on shorter transcontinental flights between cities New York and Los Angeles, jet streams can impact the flight time by nearly an hour.

Do planes fly in the jet stream?

The main commercial relevance of the jet streams is in air travel, as flight time can be dramatically affected by either flying with the flow or against, which results in significant fuel and time cost savings for airlines. Often, the airlines work to fly ‘with’ the jet stream for this reason.

Does flying east to west take longer?

Jet streams are, at their most basic, high-altitude air currents caused by atmospheric heating and the inertia of the earth’s rotation—and they’re the reason why flights from west to east are faster than the same route traversed in the opposite direction.
