General Navigation

Сложность: Medium-HighВес на экзамене: High

Обзор

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).

Ключевые темы

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

Советы по учёбе

Master the navigation computer (E6B/CRP-5) — speed and accuracy matter

Practice triangle of velocities problems until automatic

Understand map projection properties — what is preserved and what is distorted

Learn the 1-in-60 rule and its applications thoroughly

Practice chart reading with actual sectional or ICAO charts
