When navigating with a VOR, when will you experience "reverse sensing"?

The concept of "reverse sensing" occurs when the airplane is flying away from the VOR station while the navigation receiver indicates a "TO" indication for that VOR. In basic terms, the VOR receiver shows the direction to the station, and if the aircraft is headed away from it, the "TO" indication suggests that the pilot should fly towards the station, which is not the case in this situation. This creates confusion since the pilot may think they are flying toward the VOR when in fact, they are moving away from it.

For a clearer understanding, consider the implications of the other scenarios. When flying toward the VOR with a "FROM" indication, the pilot is correctly navigating towards the station, so reverse sensing is not applicable. Flying at the same altitude as the VOR does not inherently lead to reverse sensing, as altitude does not affect the direction indicated by the VOR. Lastly, if the VOR station is turned off, the equipment's reliability is compromised, but that condition does not produce the phenomenon of reverse sensing. Therefore, the correct answer underscores the importance of understanding how the VOR indications correlate with the aircraft's position relative to the station.
