ACS element text (the applicant demonstrates understanding of)

Maintain airplane control while selecting proper communications frequencies, identifying the appropriate facility, and managing navigation equipment.

Bottom line

Civilian pilots communicate with ATC on frequencies in the very high frequency (VHF) range between 118.000 and 136.975 MHz. If ATC assigns a frequency that cannot be selected, ask for an alternative frequency. VOR receivers are designed with an alarm flag to indicate when signal strength is inadequate to operate the navigational equipment.
