Although there are exceptions, most commercial airlines don’t fly directly over the Pacific Ocean for routes connecting the United States to Asia. Instead, they choose “curved” routes that hug bodies of land.
Do planes fly over the Atlantic Ocean?
A transatlantic flight is the flight of an aircraft across the Atlantic Ocean from Europe, Africa, South Asia, or the Middle East to North America, Central America, or South America, or vice versa. … Early aircraft engines did not have the reliability needed for the crossing, nor the power to lift the required fuel.
Do any planes fly over the Pacific Ocean?
They never go directly across the Pacific Ocean to get to, say, San Francisco. They take a curved pattern that brings them, if not over Canada, then near it. … Flights between the U.S. & Australia or New Zealand go directly over the Pacific waters, too.
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.
How high do planes fly over the ocean?
According to USA Today, the common cruising altitude for most commercial airplanes is between 33,000 and 42,000 feet, or between about six and nearly eight miles above sea level. Typically, aircraft fly around 35,000 or 36,000 feet in the air.
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 fighter jet cross the Atlantic?
Almost all fighter jets of today, cross the Atlantic with external fuel tanks and with the help of airborne tankers that will meet them at specified points for mid air refuelling. The external tanks can be jettisoned to increase the performance, if it gets into a surprise air fight.
Do planes fly over Antarctica?
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.
Why do planes fly so high?
The reason aeroplanes fly so high is due to improved fuel efficiency. A jet engine operates more efficiently at higher altitude where the air is much thinner, allowing an aircraft to travel faster whilst at the same time, burning less fuel.
How long does it take to fly over the Pacific Ocean?
Depending on your route, and winds, the time can vary dramatically. For example, Great circle San Francisco to Tokyo is 5124nm, which would be 9.2 hours no wind at 560 ground speed. With a jet stream tailwind of 200 kts, from Tokyo to San Francisco could take as little as 6.7 hours.
Why planes do not fly over 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 east?
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.
What happens if both engines fail on a plane over the Atlantic?
If both engines fail, the aeroplane is no longer being pushed forwards through thrust, therefore in order to keep the air flowing over the wings, the aircraft must exchange energy through losing altitude in order to maintain forward airspeed.
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 do planes fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
Can planes fly at 50000 feet?
It was set in an SR-71 Blackbird in 1976. The speed record is also held by an SR-71, at 2,193 mph. This is not as high or as fast as the airplane can fly, however, it’s absolute speed and altitude limits are classified. Most US military aircraft can exceed 50,000 feet, if they really really try.
