Which FMS page provides access to communication and navigation radio system management?

• A. FREQ
• B. INIT REF
• C. HOLD
• D. FIX

Answer: (A)

Tuning and managing the aircraft’s communication and navigation radios is done on the FMS frequency page. This page is dedicated to entering and adjusting radio frequencies, showing active and standby values for both communications and navigation systems (like COM and NAV channels). You can input a new frequency in MHz, swap to make it active, and quickly switch between radios as needed, all in one place. The other pages serve different tasks: initialization data and reference values, holding patterns, or entering fixes, rather than handling radio frequencies.
