Why are flight routes not straight?

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.

Why are flight paths 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 are flight routes curved?

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 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.

What would happen if an airplane window broke?

If by a very slim chance, the plane’s window had cracked mid-air, things would have gone south very quickly for passengers. As The Independent explained, above 10,000 feet the plane would depressurize and there would be an immediate drop in oxygen for passengers.

What is the highest altitude a plane can fly?

Question: What is the highest altitude an airplane can fly? Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet.

Do pilots adjust for curvature?

Aircraft altitude is measured (inferred) by atmospheric pressure. … 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.

Why do flights take longer routes?

A route that looks longer on the map is because of the distortion created with map projections like the Mercator projection. In navigation, pilots often use great circles (geodesic) as the shortest distance flight.

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 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.

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.

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.

Can you fly faster than the sun?

Yes – but only in theory. The Earth is roughly 40,000km in circumference at the equator, and completes one rotation every 24 hours. This means that the Sun effectively zooms across the face of the Earth at the equator at around 1,700km/h. So you’d have to travel at least this fast to stay in daylight.
