Air Navigator

  1. Understand what is meant by latitude and longitude and be able to explain the difference between a great circle and a plumb line.
  2. Understand what is meant by magnetic dip, variation, deviation, heading, track and drift.
  3. Show a knowledge of the conventional signs used in air maps and which types of landmark are most useful in cross-country flying.
  4. Plot the true heading required to make good the track between 2 places on a chart, given an airspeed and a forecast wind velocity. Given a time of departure, work out the estimated time of arrival (E.T.A.) from a timed fix indicated on the chart during an imaginary flight, work out the track made good, actual wind velocity, new track required, true heading to steer and revised E.T.A.
