June 26, 2025Jun 26 This was another fairly tough exam, you'd be given a Lamberts projection chart of the area covered by the exam, (unfortunately I don't have the chart for this paper, but the 1st link is an example of the type of charts used, just basic airways, with VOR's, NDB's, Airfields and coastlines shown). Then you'd use the chart to plot the answers to the questions. Plotting a position line given a bearing from a Nav station was straightforward, but then further positions lines were plotted at later times, and you'd be required to plot a "moving fix", using a parallel ruler to move the position line along your expected track, and using your calculated ground speed to decide how far to move it. You'd have a pretty good idea how accurate you'd been, as hopefully the position lines would intersect with just a small triangle, known as a "Cocked Hat", a large or no triangle meant you were way off! The pass mark for all these exams was 70%. A typical plotting chart: https://postimg.cc/214xWHgd The Questions https://postimg.cc/hJDVdKLg https://postimg.cc/N58y7Wf0 https://postimg.cc/d7gtKBtX
