Candidates may use any navigational methods they wish in the solution of problems, provided they are correct in principle. Because of the many different methods of computing a position line it is necessary, in order to obtain uniformity in examinations, to require as an answer either the longitude based on the D. R. latitude as solved by time sight or the longitude of the computed point as obtained by any position line method, either with plotting or traverse tables. Computed point is the point at which a perpendicular from the D. R. position (for the instant of the sight) intersects the line of position.
