True or False: Both RTUs monitor and control COM 1 and COM 2.

In the context of the CRJ550 aircraft systems, it is important to understand the function of the Radio Tuning Units (RTUs). While the RTUs do facilitate communication and operational tuning for both COM 1 and COM 2, they do not both actively monitor and control them simultaneously. Instead, typically one RTU is dedicated to each communication unit, allowing for efficient management and operation of the radios. This specialized control means that only one RTU is engaged with each COM channel at any given time, thus preventing simultaneous control by both units.

This operational design ensures that the systems remain streamlined and functional, thereby enhancing safety and effectiveness in communications. The functional separation is crucial, particularly during critical phases of flight where clarity and response time in communication are essential. Understanding this nuanced division in control and monitoring is key to mastering the operational aspects of the CRJ550 systems.
