Chapter 4

Question 1

What is a VOR radial?

Answer 1

A VOR radial is a magnetic bearing transmitted by a VOR station, representing a magnetic direction from the station.

Question 2

How do you determine your position relative to a VOR?

Answer 2

1. Tune and identify the station.
2. Rotate the OBS to center the CDI needle with a FROM indication.
3. The number under the course index represents the radial you are on.

Question 3

Does the airplane’s heading affect your position relative to a VOR?

Answer 3

No, the heading has no effect. Position relative to the VOR changes based on your radial, not your heading.

Question 4

What is the role of the OBS (Omni Bearing Selector) in VOR navigation?

Answer 4

The OBS is used to select a radial and center the course deviation indicator (CDI) needle, which tells you your position relative to the selected radial.

Question 5

What is the first step in intercepting an airway using VOR?

Answer 5

Tune and identify the VOR station, then rotate the OBS to center the CDI needle with a FROM indication.

Question 6

What are the steps to fly from 21AF to PNH via V-280?

Answer 6

1. Tune 116.6 and identify PNH
   
   2. Center with FROM = 176
   3. Locate position as south of PNH
   4. Turn to northwest at 315
   5. Set OBS to 044 (northeast)

Question 7

What are the steps to fly to PNH via V-280?

Answer 7

1. Tune 116.6 and identify PNH
   
   2. Center with FROM = 176
   3. Locate position as south of PNH
   4. Turn to northwest at 315
   5. Set OBS to 044 (northeast)

Question 8

How do you visualize your position relative to PNH when using V280?

Answer 8

Visualize your position relative to PNH (cardinal direction) and look for V280 on the chart. Follow V280 back to PNH to determine the radial that makes up the airway.

Question 9

After identifying your position on V280, what is the next step?

Answer 9

Turn to the cardinal heading which comes closest to a perpendicular intercept of V280.

Question 10

What should you do once established on the intercept heading?

Answer 10

: Set the OBS to the direction you will fly after intercepting the airway. Always adjust the OBS after intercept unless you will be tracking away from the VOR.
