Using your plotter, draw a line from the Elizabeth City VOR to extend the 340° radial to where it intersects Victor 1. Using the sectional side of your plotter and reading the nautical miles scale, measure the distance of this point from the Norfolk VORTAC: 18 NM. (Note: Don't get trapped into using the 340 feet MSL obstacle as the 340° radial.). Answers A and C are incorrect because neither distance on Victor 1 would put you on the 340° radial of Elizabeth City VOR.
Explanation:
The plane can be going in any direction as long as it is at the appropriate checkpoint on the airport's surface. OBS should be placed on the specified radial. The CDI must center with a FROM indication, plus or minus 4° of that radial. The OBS being set to 180° or 000° refers to a check utilizing a VOT, hence answers B and C are incorrect.
