Question: 1 / 400

If ATC instructs you to track outbound on the 180 radial, which OBS setting should you use?

180° and correct away from the CDI

360° and correct toward the CDI

180° and correct toward the CDI

To track outbound on the 180 radial from a VOR (VHF Omnidirectional Range), the correct setting for the OBS (Omni Bearing Selector) should be set to 180 degrees. This indicates that you are heading away from the VOR station along that specific radial.

When you set the OBS to 180 degrees and are tracking outbound, the CDI (Course Deviation Indicator) will show the needle centered as you fly exactly along the 180 radial. If the needle is deflected to one side, it indicates that you are off course. In this case, to correct your course, you need to adjust your heading towards the CDI; moving the aircraft in the direction of the needle will bring you back onto the desired radial.

This understanding of the VOR system and its operation is key for effective navigation and ensures that you maintain the intended flight path when instructed by ATC. It emphasizes the relationship between the OBS setting, CDI indications, and navigation techniques.
