VHF radio signals are commonly used for which two aviation functions?

VHF radio signals are used in aviation mainly for two functions: communications and navigation. Pilots rely on VHF voice channels to talk with air traffic control (and other aircraft), while navigation signals like VOR and localizer (VHF-based aids) provide bearing and position information to help guide routes and approaches. Weather information and surveillance aren’t delivered primarily through cockpit VHF navigation/voice channels—the former comes from weather systems and broadcasts, and the latter relies on radar and transponder signals. So the best description is communications and navigation.
