Preface

The terrain contour interval between major contour lines on a WAC is:

1.

Half that of a sectional (every 1000 feet versus every 500 feet).

2.

A quarter that of a sectional, (every 2000 feet versus every 500 feet).

3.

Actually the same as a sectional, but the sectional has extra, minor, contour lines.

4.

Gimme a break. I donít have a WAC chart to look at terrain.

And if you thought it was unfair, confusing, or a waste of time, we'd like you to tell us that, too. And if you have an idea for a subject that you think would make a good future IFR Quiz, be sure to let us know.
