How do VOR and ILS differ in navigation guidance?

• A. VOR provides altitude data.
• B. ILS provides radial guidance to a VOR station.
• C. VOR provides radial guidance to a VOR station; ILS provides precision approaches with localizer and glideslope guidance for landing.
• D. VOR stands for Visual Optical Receiver used for landing.

Answer: (C)

VOR is about locating and tracking using angular information from a ground station. The VOR receiver shows which radial you’re on relative to that station, so you can navigate by choosing a course and flying along that line, or determine your position by crossing radials from different stations. It does not provide altitude or vertical guidance. ILS, on the other hand, is a precision approach system for landing. The localizer gives you horizontal alignment with the runway centerline, while the glideslope provides vertical guidance to a safe descent angle toward the runway. This combination allows a precise approach and stabilized landing even in instrument meteorological conditions. So, the key distinction is that VOR supplies azimuthal navigation information for en route and situational awareness, whereas ILS provides a guided path to a runway with both horizontal and vertical guidance for landing. For the distractors: VOR does not give altitude data, ILS does not rely on radials from a VOR for its guidance, and VOR stands for VHF Omnidirectional Range, not Visual Optical Receiver.
