The book continues to feature the well-received additions of the past couple of years, including forms to help determine True Altitude (for the sun, planets & stars), Calculated Altitude (using the versine formula) & Azimuth (using the ABC Tables), as well as a pro forma for calculating Intercept. With 8 extra pages & an enhanced layout, there is plenty of space for making notes & calculations.
