A point {lat,lon} is a distance d out on the tc radial from point 1 if: lat=asin (sin (lat1)*cos (d)+cos (lat1)*sin (d)*cos (tc)) IF (cos (lat)=0) lon=lon1 // endpoint a pole ELSE lon=mod (lon1-asin (sin (tc)*sin (d)/cos (lat))+pi,2*pi)-pi ENDIF.
known point to another. For short distances, these problems are easily solved directly on charts, but for trans-oceanic distances, a purely mathematical solution is often a better method. Collectively, these methods are called The Sailings. Navigational computer programs and calculators commonly contain algorithms for computing all of the
Air Miles Calculator helps you calculate how many miles it is from one airport to another and provides a map, estimated flight time, time difference between cities, and estimated CO2 emissions.
Travelmath provides an online flight time calculator for all types of travel routes. You can enter airports, cities, states, countries, or zip codes to find the flying time between any two points. The database uses the great circle distance and the average airspeed of a commercial airliner to figure out how long a typical flight would take.
Total Distance. (Please draw or add points to map) Metres: { {distance.m}} Kilometers: { {distance.km}} Feet: { {distance.ft}} Yards: { {distance.yrd}} Miles: { {distance.mi}} Nautical Miles: { {distance.nmi}} Draw, measure, and share with Scribble Maps Pro.
Simply enter any desired location into the search function and you will get the shortest distance (air line) between the points, the route (route planner) as well as all important information. Of course, you can also determine distances between coordinates (latitude / longitude).
