why do passenger planes change course in a circle

by Taryn Torp 3 min read

In the world of aviation, this referred to as a “Go-Around”. Airplanes go around when there is a potential danger during the landing phase. Some reasons why airplanes might choose to go around include adverse weather conditions, runway incursion, and loss of separation.

Do airplane pilots adjust course for the curve?

Airplane pilots don’t adjust course for the curve – Flat Earth Facts If the Earth were truly a sphere 25,000 miles in circumference, airplane pilots would have to constantly correct their altitudes downwards so as to not fly straight off into outer space.

Why do planes fly in circles around each other?

This means that the aircraft are under the control of air traffic controllers for the entire duration of the flight, in order to maintain proper separation between them. (You may be surprised to know that aircraft are vertically separated by as little as 1,000 feet. It’s perfectly safe.)

Why do planes follow the Earth’S curve?

Because pilots, and these days auto pilots, fly with an altimeter. Which means they aim at the horizon, which means they are automatically constantly adjusting their angle to point towards the horizon, which will automatically cause them to follow the curve of the earth. David Boffey

Why do airplanes have holding patterns?

Different airplanes will perform their holding pattern on different flight levels to allow these patterns to overlap. However, a more unconventional reason for such a holding pattern maybe due to an malfunction shortly during takeoff resulting in the need for a inflight return to the originating airport.

Why do planes go round in circles?

Why? Answer: The maneuver you describe is usually either a 360 degree turn issued by the air traffic controller to increase spacing between your flight and another airplane, or it was one turn in a holding pattern. The one turn in a holding can occur when the expected hold time is reduced, requiring only a single turn.

Why do planes change flight paths?

Wind has the greatest impact on flight paths as aircraft need to land and take-off into the wind. As the wind changes, the flight paths change accordingly. This explains an airport's need to have multiple runways pointing in different directions. See Weather Effects on Aviation Operations.

Why do planes fly in circles before landing?

Generally, planes will circle above airports for the same reasons planes sometimes need to perform go-arounds. This could be anything from weather to an incident on the runway. Pilots have to weigh their options between circling for a little while or turning back to land at a different airport.

Why are flight paths curved instead of straight lines?

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. Q: Captain, I often follow trans-Atlantic flights between Europe and the USA.

Why do planes not fly over the Pacific?

Most commercial airlines, that operate between East Asia and the Americas, do not fly over the Pacific Ocean because of cost and safety concerns, including turbulent weather, which can be dangerous to fly over.

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.

What is it called when planes circle before landing?

It's called a holding pattern.

Why do planes turn so much before landing?

Airlines are today required to turn off plane lights during takeoff and landing. The reason this is done is because of the time it takes for our eyes to adjust to the dark. It can take our eyes between 10 to 30 minutes to adjust to darkness.

Why do planes fly at 35000 feet?

A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Most commercial airplanes cruise at an altitude of nearly 35,000 feet—around 6.62 miles (10,600 meters) in the air!

Why do planes not fly over Antarctica?

The polar regions interfere with magnetic navigational equipment, making it harder for planes to navigate. It can also be difficult for planes to connect with flight controllers because of the location's isolation.

Why don't planes fly over the Atlantic?

Early aircraft engines did not have the reliability needed for the crossing, nor the power to lift the required fuel. There are difficulties navigating over featureless expanses of water for thousands of miles, and the weather, especially in the North Atlantic, is unpredictable.

Why don't they fly over the North Pole?

The polar regions have special navigation concerns in the form of the magnetic fields which permeate them. These can make it difficult for planes to navigate because the polar areas interfere with magnetic navigational tools.

Do airlines change flight paths?

Some flights have altered their flight paths, and others have made vast changes for the times of some of their flights.

How do airlines decide which routes to fly?

It turns out airlines decide where to fly based on location, hubs, stopovers, passenger interest (both in the route and how much they're willing to pay), info purchased from airline booking companies, competition from other airlines, and a whole lot more.

Why do planes take off and land in different directions?

Pilots always take-off in the direction opposite to the direction of the windflow. This helps because the aircraft gets additional lift from the wind other than the speed of the aircraft itself.

Do the same planes fly the same routes?

2:345:07Do pilots always fly the same route and aircraft? - YouTubeYouTubeStart of suggested clipEnd of suggested clipThat largely depends on your airline.MoreThat largely depends on your airline.

What do pilots aim at?

Pilots aim at the horizon, so by doing this, if the earth is curved, they are automatically adjusting for the curve, similarly computers they use the gyroscope and the altimeter, to keep the plane at a fixed height above the earth, which will automatically adjust for the curve if there is one. Lee.

Why do you stay at a constant height above the surface of the Earth?

If you stay at a constant height above the surface of the earth then no matter what shape the earth is you will follow that shape. And if you point at the horizon also that will keep you following the contour of the earth below you.

Why is flat earth not science?

So flat earth is not science, because they don’t have an agreed on theory and have not been able to construct a valid predictive model based on their theory.

What would happen if the Earth was a sphere?

If the Earth were truly a sphere 25,000 miles in circumference, airplane pilots would have to constantly correct their altitudes downwards so as to not fly straight off into outer space. If the Earth were truly a sphere 25,000 miles in circumference, airplane pilots would have to constantly correct their altitudes downwards so as ...

Can we use the globe earth model to make predictions?

So the globe earthers have their theory and model and we can use their model to make predictions and compare the predictions of the globe earth model with our actual observations, and for the most part, the observations will match the predictions of the globe earth model.

Do airplane pilots adjust course?

Airplane pilots don’t adjust course for the curve. If the Earth were truly a sphere 25,000 miles in circumference, airplane pilots would have to constantly correct their altitudes downwards so as to not fly straight off into outer space. This is a mistake, it is not a proof the earth is flat. Airline pilots have an altimeter which they use ...

Do the globe earthers have to prove their theory?

They don’t have to prove their theory because they know the earth is flat, they don’t need a model because they know the earth is flat…. However, my point, is although the globe earthers have presented a very beautiful theory with quite an accurate predictive scientific model, that is not a guarantee it is correct.

Why do airplanes go around?

Some reasons why airplanes might choose to go around include adverse weather conditions, runway incursion, and loss of separation . In this article, we’ll cover all the following: The various reasons why airplanes choose to perform a go-around.

Why do planes circle the sky?

The Definitive Guide to Why Planes Circle the Sky. Commercial aircraft are one of the safest forms of travel, and there are many precautions put in place to ensure safety is paramount. However, it can be a little unnerving when you think you are about to land, but suddenly the aircraft pitches up and powers through the sky.

What is runway incursion?

A runway incursion is an incident where unauthorized personnel or equipment are blocking the runway. This situation can significantly impact landing safety and creates a considerable risk for all staff, equipment, aircraft involved. Fortunately, there are safety systems in place that help prevent runway incursions.

What is a go around in aviation?

Pilots sometimes encounter crosswinds that can blow the plane slightly off course; hence the flight crew performs a go-around to re-align the aircraft with the runway. A pilot must be able to visually see the runway to land by the time they reach the decision altitude.

How many incidents transpire when landing?

According to a study published by Boeing, 49% of incidents transpire when landing, compared to 14 % during the take-off phase. During take-off and landing, pilots have less time to react to problems because of the distance of the plane to the ground. Go-arounds can still be a risky maneuver if the initiation is ineffective.

How many go arounds are there in Australia?

The Civil Aviation Safety Authority (CASA) estimates that there are over 800 standard go-arounds performed a year in Australia every year. Which means there are more than two a day at an airport at any given time nationwide. There are no penalties or paperwork required when a pilot chooses to abort the landing.

How high should a pilot go around?

The altitude the pilot initiates a go-around can present a different set of risks and challenges. The crew should try to execute the maneuver about 1000 ft. If they attempt it any lower, the crew runs the risk of not being able to recover altitude in time.

What are the tracks of an airplane?

Aircraft follow tracks that are made up of predetermined sets of latitude and longitude coordinates across the ocean. For example, these are the North Atlantic Tracks (the same general principle applies to the Pacific Ocean as well). Flights traveling along the North Atlantic Tracks.

Why do airplanes use waypoints?

As aircraft fly, they pass over ground station waypoints, which helps air traffic control properly space aircraft. Increasingly, aviation is moving to GPS-based navigation, which improves flight efficiency as flights are able to fly more direct flight paths. Waypoints and airways are visible in the image below, ...

Do planes fly straight?

But as simple as it would be for flights to just travel along a great circle path, they rarely fly in a perfectly straight line. In the early days of aerial navigation, pilots followed a system of giant arrows on the ground to reach their destination. Concrete arrows were soon supplanted by radio beacons and radar.

Crowding

Urban airports tend to be crowded out and eliminated. They are a huge piece of real estate that developers lose their minds over, and so any business weakness in the airport is usually attacked by developers aiming to cover the property with condominiums.

Altitude maximums

The other thing about city flying is there is usually a major airport nearby. Now, airspaces are a lot like an upside-down wedding cake. Near the large airport, airspace is controlled right down to the ground. For the next ring, uncontrolled aircraft (e.g.

Runway use

You say “It’s a really big runway, why do they need to stack up?” Because airport procedure is that only one plane gets to use the runway at a time, no matter how big it is - because stuff can go wrong. Now they do make exceptions - the military (B-52 MITO) and extreme civil ops (the huge Oshkosh fly-in). But generally, one plane at a time.

How far apart are aircraft?

(You may be surprised to know that aircraft are vertically separated by as little as 1,000 feet. It’s perfectly safe.)

What is an instrument flight?

Instrument Flight Rules and a Flight Plan. Commercial passenger aircraft fly on so-called instrument flight rules or IFR (essentially, meaning that they do not fly by sight, but following instrument readings) and according to filed flight plans. This means that the aircraft are under the control of air traffic controllers for the entire duration ...

How high is a plane safe to fly?

It’s perfectly safe.) Aircraft flying above 18,000 feet (in the so-called “flight levels”) are required to use IFR rules and flight plans. “Most flight plans are typically programmed manually. There are some routes that are saved in our flight management system and loaded through a datalink system.

How high do commercial jets go?

These are in the form of jet routes at altitudes above 18,000 feet. Image via Skyvector.

Is JetBlue congested?

Image via Skyvector. “Jet routes are a very helpful and easy way for us to visualize our planned flight , but they can also get very congested in places such as the Northeast,” Shannon Pereira, a first officer with JetBlue, told TPG.

Can an aircraft intersect at a waypoint?

Each might be an intersection where the aircraft could make a change of jet route. These waypoints extend upwards to all altitudes, so several aircraft could intersect at a waypoint at different altitudes at the same time. While a VOR station is fixed on the ground, reference to a waypoint is a GPS coordinate.
