Latitude and Longitude (Meridians and Parallels) – Measurement of Direction

Navigation

By using the meridians, direction from one point to another can be measured in degrees, in a clockwise direction from true north. To indicate a course to be followed in flight, draw a line on the chart from the point of departure to the destination and measure the angle which this line forms with a […]

Latitude and Longitude (Meridians and Parallels) – Time Zones

Navigation

The equator is an imaginary circle equidistant from the poles of the Earth. Circles parallel to the equator (lines running east and west) are parallels of latitude. They are used to measure degrees of latitude north (N) or south (S) of the equator. The angular distance from the equator to the pole is one-fourth of […]

Latitude and Longitude (Meridians and Parallels) – Variation

Navigation

Variation is the angle between true north and magnetic north. It is expressed as east variation or west variation depending upon whether magnetic north (MN) is to the east or west of true north (TN). The north magnetic pole is located close to 71° N latitude, 96° W longitude and is about 1,300 miles from […]

Aeronautical Charts

Navigation

An aeronautical chart is the road map for a pilot flying under VFR. The chart provides information which allows pilots to track their position and provides available information which enhances safety. The three aeronautical charts used by VFR pilots are: Sectional VFR Terminal Area World Aeronautical A free catalog listing aeronautical charts and related publications […]
