Abstract: It is generally recognized by air navigators that lines of position obtained from the bubble sextant are almost always in error to a greater or lesser extent, and that as a result of these errors, the three lines of position which constitute a three-star fix usually form a triangle instead of meeting at a point. The navigator is faced then with the problem of selecting his most probable position on the basis of the evidence presented by this “triangle of position.”
