The RMP allows the pilot to see at a glance the active and standby frequencies selected for all the installed radios of each type (up to 3 VHF radios, 2 HF radios and single or dual channel SATCOM installations).Some of the main changes are explained below, with further details provided in the section “digital audio operating modes from a flight crew perspective”: Increasing synchronisation and simplifying operating procedures Some functions are controlled via a Line Select Key (LSK) and the RMP software can be programmed to give access, or not, as required (for example, CPDLC LOAD function), or to accurately reflect the aircraft configuration (for example, STBY NAV function and NAVAIDS listening). For example, if the aircraft is not equipped with an HF radio, then the associated menu key and transmissions keys will not be illuminated and pressing on those keys will have no effect. The RMP has a single part number and can be programmed such that the HMI is coherent with the installed equipment. Different cockpit layouts are available according to operators’ needs: 2 RMP + 1 ACP, 3 RMP or 3 RMP + ACP. Some functions are controlled via a Line Select Key (LSK) and the RMP software can be programmed to give access, or not, as required (for example, CPDLC LOAD function), or to accurately reflect the aircraft configuration (for example, STBY NAV function and NAVAIDS listening).Ī320 and A330 cockpits. The RMP builds on the service-proven design from the A380 and A350, but takes into account the desire to implement new functions, as well as the physical installation constraints of the A320 and A330 cockpits. The power supply has been updated with dual power supply for RMP and AMU to ensure higher levels of equipment and function availability in the case of degraded electrical configurations. Now, the RMPs (and not the AMU) manage the boomsets, headsets, hand microphones, oxygen mask microphones and loudspeakers. Wherever it is technically feasible, links are now digital between the AMU and the peripheral equipment. It now includes some of the previously external computers (such as the SELCAL box) and has a dual channel configuration with internal reconfiguration capability to improve robustness. Improving and streamlining the architecture improve aircraft dispatch capability and remove some airline maintenance tasks.integrate additional functions and provide provisions for future upgrades.
