Just in Case Youve Forgotten …
If your heading matches a value in the top half of the OBS, then you have correct sensing and To/From indications.
Key Takeaways:
- The OBS (Omni Bearing Selector) is used to determine the accuracy of sensing and To/From indications relative to an aircraft's heading.
- Correct sensing and To/From indications occur when the heading matches a value in the top half of the OBS; conversely, a heading in the bottom half results in reverse sensing and reversed To/From indications.
