CERTAIN hc/Z COMPUTATION POSSIBILITIES

Alfred H. Kerrick

Peer Reviewed

Abstract:	INTRODUCTION To the great majority of navigators the problem of arriving at values of hc (computed altitude) and Z (azimuth angle) appears to have been solved once and for all by the publication of the 9 volumes forming the set Hydrographic Office Publication No. 214. This view is quite understandable. The publication just mentioned enables the navigator to read off the values being discussed with ease and accuracy, rather than having to compute them by this or that set of tables, formulas and rules. There are many such sets and/or procedures, many of them reasonably short and accurate.Considering, then, the existence of the nearly ideal H.O. Pub. 214 resource, and those sets al of computing procedures-such as set forth in this article.
