Methods and apparatus are provided for displaying the operational parameters of a radio system located onboard an aircraft. The apparatus comprises a permanent radio display bar that shows an active radio frequency in use by the radio system and a variable radio display pad. The variable radio display pad shows multiple historical past radio frequencies previously used by the radio system and multiple predicted future radio frequencies for use along a flight plan of the aircraft. It includes a change command that allows a crew member to manually change the active radio frequency in the permanent radio display bar.
