When can Flight Management Computers automatically control a flight?

Flight Management Computers (FMC) are designed to enhance the automation of flight operations, allowing for precise and efficient management of the aircraft's flight path. The functionality of an FMC in controlling a flight includes various phases, but it is particularly optimized for the phases of takeoff, cruise, approach, landing, and roll-out.

The correct choice indicates that the FMC can manage flight operations starting from takeoff and extending through landing and roll-out. This capability involves coordinating with other systems like autopilot during the ascent after takeoff, managing its path during the descent towards landing, and allowing for an automatic roll-out upon touchdown. This level of integration and control is established to minimize pilot workload, facilitate compliance with flight procedures, and enhance overall safety.

It’s noteworthy that, while some options refer to the automation capabilities of FMCs in different flight phases, only the specified choice encompasses the full breadth of control designed for modern flight management systems, illustrating their advanced integration in automating critical segments of a flight from the moment of takeoff through to the conclusion of landing and the roll-out on the runway.
