 RADIO MANAGEMENT - DESCRIPTION AND OPERATION
____________________________________________
 1.
 General

_______ The radio management panels (RMP) centralize radio communication (VHF, HF) frequency control. They can also serve as backups of the flight management and guidance computers (FMGC) for radio navigation frequencies control (VOR, DME, ILS, ADF(if installed)). The aircraft is equipped with three RMPs which are identical and interchangeable.
