What happens to the navigation system's function if the OBS setting is rotated and the needle moves left?

• A. The aircraft is on the FROM side
• B. The aircraft is on the TO side
• C. The aircraft is out of range
• D. The aircraft is flying in a loop

Answer: (B)

When the OBS (Omni Bearing Selector) setting is rotated and the needle moves left, it indicates that the aircraft is currently flying toward the selected navigation radial, thus placing it on the "TO" side of the station. The OBS setting allows the pilot to select a specific radial from a VOR (VHF Omni-directional Range) station. If the needle moves left in relation to the selected radial, it signifies that the aircraft is approaching the selected course from the direction where the radial is projected; hence, it is moving toward that radial. In practical terms, the VOR system provides a means of navigating and maintaining a specific course. By observing the position of the needle in relation to the selected course, a pilot can determine their orientation toward the VOR station and correct the flight path as necessary. A leftward movement of the needle indicates that the aircraft is indeed headed to the station, reinforcing that the "TO" indication is appropriate in this context.
