FAA Ground School Practice Test

What radial is the aircraft crossing if the VOR receiver shows an indication of 030°?

1. 360°

2. 300°

3. 030°

4. 120°

The correct answer is: 030°

When a VOR receiver shows an indication of 030°, it indicates that the aircraft is on a radial that is 30 degrees from the VOR station. Radials are essentially lines extending outward from a VOR station in specified directions, measured in degrees from true north. In this case, the 030° radial means that the aircraft is either on the radial itself or is navigating towards the VOR station along this line of course. Therefore, 030° is indeed the radial that is being crossed, confirming that the answer is accurate. Understanding the concept of radials is crucial for navigation, as pilots rely on these measurements to determine their position relative to the VOR station and to avoid potential navigational errors.
