What is a VOT?
What is this system’s raison d'être?
How does it operate? |
|
Definition
VHF Omni Test
Use a VOT in order to check that your OBS is operating correctly.
Always radiates (transmits) a 360-degree test signal. |
|
|
Term
|
Definition
1) Dial in 360 FROM (since it radiates 360, so you’ll always be at a 360 radial FROM it, WHEREVER you are)
2) Verify a CENTERED needle
Or, dial in 180 TO, and verify a CENTERED needle. |

|
Definition
1) Tune in the VOR frequency in the navigation radio
2) Verify the Morse Code identifier
3) Determine which radial you are on by turning the OBS (Omni Bearing Selector) knob until the CDI (Course Deviation Indicator) needle is centered and you have a FROM indication
4) Read the heading #. |
