What is the role of flight control computers in the CRJ?

The role of flight control computers in the CRJ is pivotal as they directly control the ailerons, elevators, and rudders, which are essential components for managing the aircraft’s attitude and flight path. These computers process inputs from the pilots and various aircraft sensors to ensure precise movements of the flight control surfaces, facilitating stable flight dynamics and responsiveness to changes in control inputs.

The flight control computers also play a critical role in the aircraft's overall handling characteristics, allowing for safe and efficient maneuvering during all phases of flight. Their capability to automatically adjust the control surfaces based on real-time data enhances both safety and performance, and is essential for modern fly-by-wire systems utilized in the CRJ series.

In contrast, the other options present functions that are not typically managed by flight control computers. Monitoring passenger comfort relates more to in-flight services, regulating fuel burn rates pertains to the engine management systems, and overseeing cabin pressure and environmental systems involves separate systems typically managed by different onboard computers.
