Instrument Rating Checkride Practice Test

When navigating from VOR to VOR, when should you change frequencies?

1. At every waypoint

2. At the changeover point depicted on the airway

3. When cruising above 10,000 feet

4. Whenever the controller asks

The correct answer is: At the changeover point depicted on the airway

Changing frequencies at the changeover point depicted on the airway is the correct procedure when navigating from VOR to VOR. This changeover point, typically marked on aeronautical charts, indicates the optimal location for switching from one VOR station's frequency to another, ensuring that pilots maintain the best signal reception. Using this point helps to reduce confusion and enhance situational awareness, as these designated points are calculated based on the range of the VORs and the geography of the area. This ensures that as you approach the changeover point, you are still connected to the VOR providing guidance without any interruption in navigation signals. The other options, while they might seem reasonable in different contexts, do not follow the standard practices for VOR navigation as accurately as the changeover point does. For example, changing frequencies at every waypoint might lead to frequent and unnecessary changes, which could complicate navigation and increase workload. Similarly, switching frequencies solely due to altitude does not align with the defined airspace operations. Finally, changing frequencies only when a controller asks could disrupt your navigation flow, as it may not coincide with the ideal designated frequency change.
