Gary, British brand UNIQUE offered several sliderules of cheap construction, but interesting scale layouts. Among them was so called "Unqiue navigational". In addition to normal log scales it featured sine and tangent scales located both on slide rule body AND slide. Allegedly this would make certain trig calculations easy. Whould it be more convenient to calculate a celestial fix with this layout? If not, what other navigational calculations would be simplified? Unique Navigational may be seen on various places on the internet, for example here: http://www.mathsinstruments.me.uk/page14.html --~--~---------~--~----~------------~-------~--~----~ Navigation List archive: www.fer3.com/arc To post, email NavList@fer3.com To , email NavList-@fer3.com -~----------~----~----~----~------~----~------~--~---
