Many thanks Peter - I have shown my ignorance simply because I have never used sight reduction tables. We always worked our intercept from the DR using (initially) the basic tables, Norries or Burtons. In later years, I did get round to using a scientific calculator - but this was not even a programmable type......but it did eliminate going through all the tables for Log Cos Lat, Log Cos Dec etc. etc.
