The present invention is a communication system for implementation on-board an aircraft. The communication system includes an Audio Control Panel (ACP) including a first input device associated with an installed component and a second input device associated with an uninstalled component. The communication system further includes a Radio Interface Unit (RIU) which is communicatively coupled to the ACP. The communication system further includes an Engine Indicating and Crew Alerting System (EICAS) which includes a Display Management Computer (DMC), the EICAS being communicatively coupled to the RIU and an Aircraft Personality Module (APM) of the communication system. The DMC may be configured for evaluating an input device status (generated based upon an input received via the second input device) against an APM configuration file, and based upon said evaluation, providing an aural and/or visual alert to a user that an input device associated with an uninstalled component has been activated.
