  • 610662

    No dispute about the angle.
    The answer says distance between the two points is 562, but I am measuring well over 600.
    What am I missing?

      Hi
      It is believed that this question is no longer used in the examinations, however, it is still good practice for plotting. If you use dividers to measure the chart or the annex between the two points and then lay them along a meridian you will find that they span 9 degrees and just over 20 minutes of latitude. 1 degree is 60 NM and 1 minute is 1 NM so the distance is just over 9 x 60 (540) plus just over 20. The given answer of 562 is therefore correct.
      Hope this helps.

          Thanks JJ, but shouldn't we be able to get the same distance by measuring it using the scale in nautical in the right side of the chart? using that scale I find a little more than 600NM for the distance.

          Question is, should we use the scale from the chart or use the meridian instead to measure distances?
