Multiple Choice

Hawkins Field is how many miles away from Magnolia VORTAC along radial 190?

The distance along a VORTAC radial is read along the line extending from the VORTAC. If Hawkins Field lies on the 190-degree radial from Magnolia VORTAC, you determine how far away it is by reading the mileage along that radial from the VORTAC to the field. Charts or DME from the VORTAC will show this distance. In this case, Hawkins Field is published as being 10 miles from Magnolia VORTAC along the 190 radial, so the correct choice is ten miles. This illustrates how radials define a line and distances along them are the measure from the nav aid to the fix on that line.
