Longitude and Latitude II

Welcome to class!

In today’s class, we will be talking more about longitude and latitude. Enjoy the class!

The distance along the Great Circles:

The radius of the earth is approximately 6400 KM. the distance between any two points on P and Q on a great circle is given by the formula

$A r c P Q = θ / 360 \times 2 π R$

where o is the angular difference between points P and Q.

R is the radius of the earth.

The distance along Parallel of Latitudes:

$A r c P Q = θ / 360 \times 2 π r$ $W h e r e r = R \cos θ$

The distance between any two points X and Y along a parallel of latitude is given by the formula

$X Y = θ / 360 \times 2 π R \cos θ$

$S p e e d = (D i s \tan c e) / (T i m e t a k e n)$

Time or speed of aircraft can be calculated after obtaining the distance by using the formulae of distances along longitude and latitude

$T i m e t a k e n = (D i s \tan c e) / s p e e d$

We hope you enjoyed the class.
