FAA Ground School Practice Test

If the VOR receivers indicate the 245° radial of Sulphur Springs VOR-DME and the 140° radial of Bonham VORTAC, where is the aircraft's approximate position?

1. Dallas Fort Worth Airport

2. Glenmar Airport

3. Bonham International

4. Sulphur Springs Regional

The correct answer is: Glenmar Airport

To determine the approximate position of the aircraft based on the indicated radials from the VOR receivers, we first need to visualize the situation. The VOR system works by providing directional information based on radials—imaginary lines radiating from the VOR station. In this case, the aircraft is on the 245° radial from the Sulphur Springs VOR-DME and the 140° radial from the Bonham VORTAC. To understand where these two radials intersect, we can draw both on a map. The 245° radial from Sulphur Springs indicates that the aircraft is located southwest of Sulphur Springs, because it is the direction in which the radial is heading from the VOR. The 140° radial from Bonham points southeast from Bonham. When these two radials are plotted, their intersection indicates where the aircraft is located. Close examination of the map should reveal that this intersection aligns near Glenmar Airport. Therefore, this option accurately describes the aircraft's position relative to the VOR stations. Other locations, such as Dallas Fort Worth Airport, Bonham International, and Sulphur Springs Regional, do not align at the intersection defined by those specific radials when accurately plotted. Therefore, the
