FAA Electronic Navigation Exam 1

Question 1

(Refer to Figure 20.) What is your approximate position on low altitude airway Victor 1, southwest of Norfolk (area 1), if the VOR receiver indicates you are on the 340° radial of Elizabeth City VOR (area 3)?

Accepted Answer

18 nautical miles from Norfolk VORTAC.

Answer

To find your position, locate Elizabeth City VOR (area 3) on Figure 20. Draw a line extending from the VOR along its 340° radial (which is 340° magnetic from the VOR). Next, locate low altitude airway Victor 1 (the blue line) southwest of Norfolk (area 1). The point where the 340° radial intersects Victor 1 is your approximate position. Using the nautical mile scale on the chart, measure the distance from this intersection point to the Norfolk VORTAC (area 1), which will be approximately 18 nautical miles.

Question 2

(Refer to Figure 20, area 3; and Figure 28.) The VOR is tuned to Elizabeth City VOR, and the aircraft is positioned over Shawboro. Which VOR indication is correct?

Accepted Answer

9.

Answer

First, locate Elizabeth City VOR (area 3) and the town of Shawboro on Figure 20. Draw a line from the VOR to Shawboro. This line represents the aircraft's position relative to the VOR. By aligning this line with the VOR rose, you can determine that Shawboro lies approximately on the 255° radial from the Elizabeth City VOR. Since the aircraft is positioned *over* Shawboro, it is *from* the VOR. Therefore, the correct VOR indication (Figure 28) would show the OBS set to 255°, a centered CDI, and a FROM flag, which corresponds to illustration 9.

Question 3

(Refer to Figure 21.) What course should be selected on the omnibearing selector (OBS) to make a direct flight from Mercer County Regional Airport (area 3) to the Minot VORTAC (area 1) with a TO indication?

Accepted Answer

A. 359°.

Answer

To determine the course for a direct flight from Mercer County Regional Airport (area 3) to Minot VORTAC (area 1) with a TO indication, draw a straight line between the two points on Figure 21. Measure the magnetic bearing of this line from Mercer County to Minot. Using a protractor or by visually estimating against the VOR rose, the course from Mercer County to Minot is approximately 359°. For a 'TO' indication, the OBS should be set to the magnetic course *to* the station.

Question 4

(Refer to Figure 23.) What is the approximate position of the aircraft if the VOR receivers indicate the 320° radial of Savannah VORTAC (area 3) and the 191° radial of Allendale VOR (area 1)?

Accepted Answer

Briggs private airfield.

Answer

To determine the aircraft's position, plot the two VOR radials on Figure 23. From Savannah VORTAC (area 3), draw a line along the 320° radial (northwest). From Allendale VOR (area 1), draw a line along the 191° radial (south-southwest). The intersection point of these two radials indicates the aircraft's approximate position. This intersection falls directly over Briggs private airfield, making it the correct answer.

Question 5

(Refer to Figure 23.) On what course should the VOR receiver (OBS) be set to navigate direct from Hampton Varnville Airport (area 1) to Savannah VORTAC (area 3)?

Accepted Answer

196°.

Answer

To navigate direct from Hampton Varnville Airport (area 1) to Savannah VORTAC (area 3), draw a straight line between these two points on Figure 23. Then, measure the magnetic course of this line from Hampton Varnville to Savannah. By aligning a protractor or visually estimating with the VOR rose, the magnetic course is approximately 196°. This is the course that should be set on the VOR receiver's OBS for a direct flight with a TO indication.
