- 1AIR NAVIGATIONThe process of piloting an aircraft from one geographical location to another, while monitoring the position as the flight progresses.
- 2Aeronautical chartsAn aeronautical chart is the roadmap for a pilot flying under VFR. The chart provides information which allows pilots to track their position and provides available information which enhances saftey.
- 3Sectional chartThe most commonly used charts today. Are scaled 1:500,000( 1 in.=6.86 NM) This allows for more detailed information to be included on the chart.
- 4VFR terminal area chartAre helpful when flying in or around airspace class B. They are scaled 1:25,000 (1 in.=3.43 NM). These charts provide a more detailed display of topographical information.
- 5World aeronautical chartWorld aeronautical charts are designed to provide standard series of aeronautical charts, covering land areas of the world, at a size and scale convenient for moderate speed aircraft, they are produced at a scale of 1:1,000,000(1in. =13.7NM)
- 6LatitudeImaginary circles parallel to the Earth's equator, called latitudinal parallels, are used to measure degrees of latitude 0-90 degrees north or south of the the equator.
- 7Meridians of longitudeare used to measure east or west degrees. The prime meridian which passes through Greenwich, England is used as the zero line. Which degrees are measured east or west to 180 degrees. Meridians are also useful for designating time zones.
- 8Time ZoneA time zone is established for every 15 degrees of longitude. This means there is a difference of 1 hour for each time zone.
- 9CourseIntended path of an aircraft over the ground or the direction of a line drawn on a chart representing the intended aircraft path, measured from a specific reference datum clockwise from 0 degrees through 360 degrees.
- 10WCAcorrection applied to the course to establish a heading so that track coincides with course.
- 11headingdirection in which the nose of the aircraft points during flight
- 12VariationVariation is the angle between true north and magnetic north.
- 13Magnetic heading (MH)obtained by applying variation to true heading
- 14Deviationbecause of magnetic influences within an aircraft such as electrical circuits, radio, lights, tools, engine and magnetized metal parts the compass needle is frequently deflected from its normal reading
- 15Compass headingreading on the compass found by applying deviation to magnetic heading
- 16Transition layerThat portion of airspace between the transition level and transition altitude.
- 17ReciprocalThe return trip
- 18Air speedRate of an aircraft's progress through the air
- 19Ground speedThe rate of an aircraft's in-flight progress over the ground
- 20isogonic lineconnect points of equal magnetic variation
- 21Agonic lineA line where magnetic north and true north coincide, and zero degree variation exists.
