(35) Additional Moonbounce Operating Aids
An algorithm from the article A Simple Program to Calculate Distance On a Spherical Earth, Additional Moonbounce Operating Aids (EIMACS).

One of the first things we do after a QSO is to check the mileage to see what kind of DX we have worked. Sometimes we may even have a computer generated list, but seldom do we have the exact location we need. This simple program can be used on an HP21 or HP35 (and probably other scientific calculators) and will quickly give us the distance in statute miles {the basis for present distance record purposes}. All you need to know is your longitude and latitude and that of the station worked. This program is an outgrowth of an example in the HP21 instruction manual and an earlier QST article, "Bearing and Distance Calculations by Sleight of Hand", KlPLP, QST for August 1973, pp 24-26.

BEST!
