An extract from Nonsymmetric Ballastic Range, Height, Time-of-Flight, and Optimal Flight Path Angle Computations with programs for a Hewlett-Packard Calculator., Naval Postgraduate School, Report # NPS55Su76031, MAR 1976 (17 pages).

ABSTRACT
The purpose of this report is to provide the equations and HP-65 Programmable Calculator programs for computing ballastic range, height, time-of-flight, and particularly the flight path angle which maximizes ballistic ranges for non-symmetric launch and target positions. A no-atmosphere, non-rotating, spherical Earth is assumed.

All of the computational methods are outlined in Section III. Instructions and a sample problem for the Hewlett-Packard 65 Calculator (HP-65) are given in Section IV. This HP-65 programs are in Section V, and the development of the ß⒪⒫⒯ procedure is in the Appendix. Familiarity with Newtonian two-body theory is assumed.

The HP-65 program consists of four magnetic cards …
