Flight Distance Calculator – Calculate Distance

Having this information for how far the departure airport is from the destination can help someone have an easier time planning their flight. Whether you are wanting to calculate the flight distance for travelling domestically, planning an international trip, or just for comparing distances for different travel options.

A Flight Distance calculator allows the user to calculate the approximate distances between two specified airports or cities. Simply type out where you want to depart from and your destination in order to calculate how far your flight will be and find out the distance in miles, kilometres or nautical miles.

We often calculate the distance passed by planes in miles from many places in the U.S. For example, you could want to calculate how far New York is from Los Angeles, Chicago to Miami, or Dallas to San Francisco.

Most calculators work using the great circle distance formula to provide the shortest distance between two points. This accounts for the curved surface of the earth.

However, planes will not always travel this distance due to certain factors.

Whether you are a regular traveller, you work in a job requiring you to travel, a student or interested in visiting a lot, the Flight Distance calculator will provide you with the distance between many destination coordinates making up your travels much easier.

How to Use

In order to give the most accurate distance between airports, type specific airports to calculate.

Calculating using the flight distance calculator formula

Most flight distance calculators use the Haversine formula.

This formula will give the shortest distance between two points.

Formula:

a = sin(Δφ/2)² + cos(φ1).cos(φ2).sin(Δλ/2)²

c=2 = arctan2(√a, √(1−a))

d=R x c

Where:

d Great circle distance

R Mean earth radius = 3959 miles or 6371 kilometres

1 Latitude of departure

2 Latitude of destination

The difference in latitudes

Difference in longitudes

c Angular distance between the two destinations

The distance is shown either in miles or kilometres depending on what you wish your distance to be.

If wanting to extra from distance in navigational miles: Multiply by 1.15078

1 Nautical Mile = 1.15078 Statute Mile

This formula when carrying our calculations is commonly used when travelling.

Worked Example

Imagine you are heading on a flight from New York to Los Angeles and want to calculate the approximate distance.

Flight Details

Departure:

JFK, New York

Destination:

LAX. Los Angeles

Distance Type:

Mile

Calculation Method:

Great Circle Distance

This gives us an approximate great circle distance of 2,475 miles.

This is calculated using the Haversine formula. It uses the latitude andlongitude co-ordinates:

Appointment 거리 :

This calculates approximately: 2,475 Miles 3,983 Km 2,151 Nautical Miles.

This means there would be approximately 2,475 miles between these two airports.

However, the airline may fly slightly further due to air traffic, bad weather and operations.

This example shows how this resource can help you understand how far major airports in the U.S. are.

Understanding your results

After filling out your departure and destination the calculator shows you the distance of your destinations.

Understanding the meanings behind the distances can definitely help.

Flight Distance (Miles):

Shows you an approximate distance in statute miles. This is commonly used when planning domestic travel in the U.S..

Flight Distance (Kilometres):

Shows you the distance in km. This is very helpful for international travel. Gives you information to compare different destinations:

Flight Distance This is commonly used in aviation for static miles.

( Nautical Miles ):

Navigation miles are commonly used. 1 nautical mile = 1.15078 statute miles.

Great Circle Distance:

This means the distance between to points along the earth’s surface in its shortest form, assuming the Earth is a sphere.

Actual Flight Distance:

The distance is based on geography meaning it may not give you the actual distance travelled. Commercial airliners will often travel much further due to weather, navigational restriction and air traffic.

Just because one place is further away, doesn’t mean it will the flight time will be much longer. Depending on your speed, wind etc can have an effect.

The Different Variables Affecting Distance

There are many variables that can affect how far the plane will actually travel.

1. Departure/destination airports

Some airports might be prpoerly placed within the same city giving you a different geographical position. Flying from Newark Liberty International Airport instead of JFK will give you a tiny bit more or less of distance.

2. Airlines flight route

Airlines won’t always take the shortest route. Air traffic, operations and restricted airspaces can cause longer routes.

3. Weather

Strong weather conditions such as thunderstorms, strong winds and turbulence might cause pilots to fly different routes.

4. Connecting flights

Adding more connecting flights will give you more distance travelled. Each variable will need calculating individually.

5. Earth curvature

The globe curves so the great circle distance will have been used. This is appropriate for long distance travel.

6. Airspace restrictions

Some military zones, restricted airspace etc can cause planes to avoid travelling.

7. Air traffic

Air traffic can cause planes to take different routes. Along with busy airports and separation requirements.

Benefits

Flight Distance Calculators provide many benefits.

Accuracy/Assumptions/Limitations

The Flight Distance Calculator gives you the approximate distance between your destinations. It will be based on the data from the airports.

Assumptions：

Most calculators will assume the earth to be a sphere and calculate based on great circle distances.

Limitations:

Your results will rely on accurate latitudes and longitudes of your departure & destination airports.

Commercial planes may vary and fly further due to weather, air traffic, restricted airspace and airline sent-up.

Connecting flights won’t automatically be included from the calculation. They will need to be calculated individually.

Flight times can vary greatly. Speed, wind & operations.

The units will vary. Miles, km & nautical miles. Double check which distance unit has been chosen.

Also depending on what city you’ve chosen as the airport, this may vary from distance between airports.

For the most accuracy choose exact deal positions. If you wished to know the actual distance travelled or current flight details visit airline booking details or a reliable flight tracking website.
