Best answer: Why are some flights longer than others?

1) airports busier at certain times of day so more queueing to takeoff/land/taxi. 2) a different type of aircraft scheduled to operate the flight. They don’t all fly at the same speed.

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.

Why do flight times vary?

The main reason for the difference in travel time is due to the jet stream. The jet stream is high altitude wind that blows from the west to the east across the globe. Airplanes fly into the jet stream at 30,000 feet and then travel with these winds.

Do longer flights fly higher?

The long haul flights generally cruise at 29000 ft to 43000 ft. Not lower or higher than these. If they fly at lower altitude they will disrupt the domestic or short haul flight routes. The domestic aircraft generally travel at lower altitudes as their flight is shorter and it is economical.

Why are flights shorter one way?

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.

Why do planes do 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 do jets 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 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.

Why are flights faster going 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.

Does rotation of the Earth affect flight times?

It affects flight time the same way that it affects driving time. … If the air is not moving the same as the ground, it’s called wind, which is the primary influence on flight time. Wind is influenced by the earth’s rotation, but the rotation doesn’t directly influence flight time.

How cold is it at 35000 feet?

How cold is it up there? The higher you get, the colder it gets, up until 40,000 feet. If the temperature at ground level was 20C, at 40,000 feet it would be -57C. At 35,000 feet the air temperature is about -54C.

Can you breathe at 35000 feet?

Whether you are flying aboard a small Cessna or a jumbo-sized Airbus A380, you can breathe freely inside the cabin without wearing a mask or respirator. Even at a cruising altitude of 35,000 feet, you shouldn’t have trouble breathing.

Are planes checked before every flight?

Some people think that before taking off in an airplane the pilot simply has a casual glance at it. Perhaps he kicks the types, checks the fuel gauges to makes sure he has enough fuel, and then just departs. But this is very far from the case. All good pilots use pre-flight checklists before every flight.

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.

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.

Does the Earth spin under a plane?

The reason is something called ‘inertia. ‘ The Earth always spins toward the east. Suppose you’re about to take off in an airplane, in that same direction. Whether you realize it or not – as you sit on the runway – your plane is already moving at the same speed Earth spins.
