To tune one of the radios to the desired frequency, we simply type in the numerical part of the frequency using the number keys and hit the key-select button adjacent to where we want the frequency to go. The tuning and control panel on the 787 Dreamliner. The TCP gives us two options for each radio - "active" for the frequency we wish to receive and transmit on and "standby" for a frequency that we would like to have ready to use at the push of a single button. VHF-L is used primarily for communications with the active ATC frequency, VHF-C for our datalink and VHF-R to keep a listening watch on the emergency frequency, 12.5. On the 787, the three VHF radios are identified as "VHF left," "VHF center" and "VHF right." The tuning and control panel (TCP) is - unsurprisingly - used to tune and control all three VHF radios. Not only does this give us backups in case of a failure, but it also allows us to use to a number of different frequencies at the same time. Most commercial aircraft will have three separate VHF radios.
