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 are flight routes not straight?
Despite what some theories suggest, the Earth is not flat, and so curvature becomes an incredibly important factor in routes aircraft take. Similar to the Earth itself, aircraft, therefore, take flight routes that also appear to be a curved line, tracing the Earth’s shape.
Why don’t planes fly straight across 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 do planes look like they are flying straight up?
Due to the curvature of the earth, planes flying directly towards you appear to be rising vertically even though they are at a constant distance from the earth’s surface. It is the same effect as ships that appear to be rising from the sea as they draw near to the observer.
Why do planes only fly one way?
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.

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.
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.”
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.
What is the longest direct flight?
Singapore Airlines’ direct flight from Singapore to Newark, New Jersey, is currently the longest flight in the world, lasting around 18 hours and 30 minutes and traveling 9,534 miles.
Do planes dump toilet waste in the air?
Blue ice, in the context of aviation, is frozen sewage material that has leaked mid-flight from commercial aircraft lavatory waste systems. Airlines are not allowed to dump their waste tanks in mid-flight, and pilots have no mechanism by which to do so; however, leaks sometimes do occur. …
What happens if a plane flies too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
Why are planes flying so low?
Why are the airplanes flying so low over my house? Aircraft are limited in the direction they fly because they must land into the wind. Therefore, the flexibility of air traffic is dependant on the wind patterns of the day or, even, the hour, as winds can change rapidly.
Why do planes never fly over Antarctica?
A Lack of Infrastructure. It is fair to say that there isn’t much infrastructure on Antarctica at all, let alone towers and airports and other structures which can help airplanes take off, land, and navigate. The lack of such an infrastructure can make flying over Antarctica like flying over the sea.
Can a plane fly faster than the Earth rotates?
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.
Do planes adjust for 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.
