• Rhumb lines are straight lines

• Rhumb lines are curved lines convex to the equator

Which of the following is a property of the Lambert Projection Chart?

• Rhumb lines are straight lines

• Rhumb lines are curved lines concave to the nearer pole

• Rhumb lines are curved lines convex to the nearer pole

Which of the following text states the two qualities that make an aeronautical chart 'orthomorphic'?

• (1) Constant scale and shape over the entire chart, and

  (2) parallels of latitude and meridians of longitude intersect at right angles

• (1) Constant scale or constant scale expansion in all directions over a small area, and

  (2) parallels of latitude and meridians of longitude intersect at right angles

• (1) Constant scale or constant scale expansion in all directions over a small area, and

  (2) parallels of latitude and meridians of longitude intersect at constantly varying angles

• (1) Constant scale and shape over the entire chart, and

  (2) parallels of latitude and meridians of longitude intersect at constantly varying angles

A Mercator Chart is useful for navigating …?

• at all latitudes

• between 30°N and 30°S

• between 70°N and 70°S

• close to the poles

Where on a Lambert's Conformal Chart is the scale compressed?

• outside the standard parallels

• this is not applicable to Lambert's Conformal Charts

• through the entire chart

• within/between the standard parallels

What chart projection is produced by placing a cone over a globe parallel to the Earth’s polar axis?

• Lambert’s polar spheroid

• Lambert's conformal chart

• Mercator chart

• Mercator polar spheroid

What unit of measurement is used to indicate spot height elevations on New Zealand VPC and VNC charts

• meters above ground level

• meters above mean sea level

• feet above ground level

• feet above mean sea level

The solid line A to B indicated by the arrow in this diagram is ….

• a great circle

• a small circle

• the equator

• a rhumb line

What chart projection is produced by placing a cylinder tangential to the equator?

• Lambert's conformal chart

• Mercator chart

• Mercator polar spheroid

• Transverse Lambert’s chart

• Transverse Mercator chart

What is the major disadvantage of the Mercator chart?

• The chart can only be used at latitudes between 70°N and 70°S

• It is not possible to show the equator

• Great circles cannot be plotted (because they are curves)

• Rhumb lines will appear as straight lines
