General Navigation

कठिनाई: Medium-Highपरीक्षा भार: High

अवलोकन

General Navigation covers the fundamentals of air navigation: Earth geometry, map projections, dead reckoning, in-flight navigation techniques, and solar system basics. This subject is calculation-heavy and requires proficiency with the navigation computer (E6B or CRP-5).

मुख्य विषय

  • Earth geometry — great circles, rhumb lines, convergency
  • Map projections — Lambert, Mercator, Polar Stereographic
  • Direction — true, magnetic, compass headings
  • Distance, speed, and time calculations
  • Dead reckoning navigation
  • Triangle of velocities and wind correction
  • In-flight navigation techniques (track keeping, ETAs)
  • The 1-in-60 rule
  • Charts — scale, symbols, datum
  • Solar system — seasons, day/night, twilight

अध्ययन टिप्स
