🔍 Key Concepts

• How VOR provides directional (azimuth) information to aircraft • Use of phase differences in AC signals to encode angular position • Difference between determining azimuth (bearing) and determining distance or altitude

💭 Think About

• Ask yourself: Does a VOR help a pilot know how far they are from the station, which direction they are from the station, or how high they are above it? • Which of the choices correctly connects phase difference in AC voltages with the idea of bearing/radial from the station rather than range or altitude? • Think about which system (VOR vs. DME/altimetry) is normally associated with distance and altitude information.

✅ Before You Answer

• Identify which answers refer to distance or altitude and which refer to direction/azimuth • Check which option uses phase difference between two AC signals and links it to azimuth/bearing information • Eliminate any option that mixes up what VOR does (direction information) with what other systems do (distance or altitude).
