Where are the controls for the radio systems located in a Cessna 172?

The controls for the radio systems in a Cessna 172 are situated on the center console or instrument panel. This placement allows the pilot to have easy access to the radio equipment while ensuring that these controls are at a convenient location for operation during flight. The instrument panel, where the primary flight instruments are located, is designed for quick reference, enabling the pilot to manage navigation and communication effectively without having to divert their attention too far from flying the aircraft.

Accessibility is critical for safety and ease of operation, which is why the center console or instrument panel is the most logical location for these controls compared to other options like under the pilot's seat, on the cabin roof, or in the cargo area where access would be cumbersome and impractical during flight operations.
