3.02 Using Charts

• MTPs:– Using Aeronautical Charts– Types of Charts– Symbols on Charts– Measuring Distance– Tracks and Bearings

Using Aeronautical Charts

• How charts differ from maps:• Control Zones• Aerodrome Information• Ground Elevation• Lines of Variation• Airspace Information• Communication/ Navigation Aids

Types of Charts

• VNC (VFR Navigation Chart):– Lambert Conformal Conic Projection, 1:500 000 scale– Used to enable visual navigation (lower level, low

speed)• VTA (VFR Terminal Area Chart):

– Transverse Mercator Projection, 1: 50 000 scale– Used to illustrate landmarks, call points, and control

zones in a terminal area (e.g. Vancouver)• WAC (World Aeronautical Chart):

– Lambert Conformal Conic Projection, 1:1 000 000 scale

– Designed for visual navigation (higher levels, greater speed)

Symbols on Charts

• Charts:– Where to find the chart legend– How to interpret symbols

Measuring Distance

• To Measure Distance on a Chart– Use ruler and chart scale

Tracks and Bearings

• Track:– Proposed path over the

ground• Track Made Good:

– Actual path over the ground

• Track Error:– Angle between track and

track made good• Bearing:

– The direction or angle from one point to another
