Sextant Piloting The process of using a sextant to measure vertical angles (i.e. height of a hill or bridge clearance) or horizontal angles (i.e. width of an islet or bay entrance, or distance between two landmarks) to find a distance off or position on a chart. Sextant piloting is the most accurate means of piloting, so much so that it is often called surveying. Examples are given in the book How to Use Plastic Sextant: With Applications to Metal Sextants and a Review of Sextant Piloting. |
