  1. 5. The name given to the grid overlaid map in order that position may be defined
  2. 7. A system of navigation which allows a pilot to fly a selected course to a predetermined point without the need to overfly ground-based navigation facilities.
  3. 9. An antenna, located at the far end of the runway, that provides horizontal guidance.
  4. 11. The angle subtended at the centre of the earth by the arc of the meridian between the equator and the particular point.
  5. 13. The path pursued by a moving body or the point to which one moves, or at which one looks.
  6. 14. The rate of movement through the air mass in which the Acft is flying.
  7. 16. A navigation technique to estimate your position by using your last known location and then calculating your subsequent position based on your speed, direction, and the time you've traveled.
  8. 18. An antenna, located adjacent to the designated touchdown zone of the runway, that provides vertical guidance.
  9. 19. Curved lines drawn on the surface of the earth possessing one important property: they cut all meridians at the same angle. Also known as a loxodrome.
  10. 21. The angle between the aircraft’s heading and its track

  4. 4. Term used to describe the shape of the earth.
  5. 6. The ratio of the TAS to the local speed of sound
  6. 8. The average length of one minute of arc at a great circle.
  7. 10. The angle subtended at the centre of the Earth by the shorter arc at the equator between the Prime Meridian and the meridian of the particular point.
  8. 12. Semi-great circles joining the poles.
  9. 13. The difference between compass north and magnetic north
  10. 15. The actual speed of the Acft relative to the earth's surface.
  11. 17. That particular great circle whose plane is at right angles to the axis of rotation. It divides the earth into the North and South hemispheres.
  12. 20. The actual passage of the Acft over the earth's surface.
