Which statement accurately describes VHF signals in aviation?

• A. They are used only for weather broadcasts
• B. They are commonly used for communications and navigation
• C. They are used solely for satellite communications
• D. They are not used in aviation

Answer: (B)

VHF signals in aviation are used because this band supports reliable, short-range, line-of-sight communications and navigation aids that pilots rely on. The VHF range allocated for aviation is set up for two-way voice communication between pilots and air traffic control, which is essential for clear coordination during all phases of flight. It also hosts ground-based navigation aids like VORs and the ILS localizer, which provide pilots with bearing and precise course guidance. That combination—direct, intelligible voice communication and accurate navigation signals—makes VHF ideal for both talking to controllers and navigating. Saying VHF is used only for weather broadcasts isn’t accurate, since weather information is distributed through various channels but VHF is not limited to weather. And satellite communications use different frequency bands, not the primary aviation VHF range, so that isn’t the main use of VHF aviation signals. VHF is indeed used in aviation, for both communication and navigation.
