We show how to use "SR Methods & Fix" section of Stan Klein's Celestial Tools PC app to check each individual step of a sight reduction by any method (249 v23, 249 v1, 229, NAO, 211, 214, S-table, and direct trig solution). The pub 249 v23 examples shown are taken from our cel nav textbook ( [ Ссылка ] ). The Celestial Tools app can be downloaded at [ Ссылка ].

Another valuable training resource for mastering advanced cel nav, just mentioned in passing in the video (Hawaii by Sextant), can be seen at [ Ссылка ]. which explains why there is no other book like this in the past, nor likely in the future.
