19. LOXODROME AND GREAT CIRCLE NAVIGATION TOGETHER, GREAT CIRCLE TRIANGLE COLOURED GRAPH PRINTED OUT.

This program calculates the well known loxodrome and great circle problems of navigation; i.e. two (direct and inverse of loxodrome) and other two (direct and inverse of great circle navigation).

The newness of this program is the immediate double calculation (loxodrome and great circle)and in this way it is possible to see the difference between two distances calculated and also to choose the more suitable navigation.

In left side of your monitor you can see loxodrome navigation data to be compared with great circle navigation data in the right side. High in the central part of the monitor there is the great circle triangle with the departure and arrival points.

The program calculates also the top of the great circle curve i.e. the vertex with his latitude and longitude. As well known, this is very important to avoid dangerous navigation in the high latitudes. We suggest do not forget these calculations because it is very important that satellite or GPS are to be always checked.

Windows95 or Windows98 as follows:
1) To have coloured graph in the monitor; in our case the great circle triangle.
2) Push the "STAMP" key in the right side of your keyboard.
3) Open "mspaint" program and click on MODIFY menu and then in the PASTE option.
4) The graph will appear and you can change also all colours and print.
