What capabilities do AFCS systems on jet transports commonly have?

AFCS, or Automatic Flight Control System, on jet transports typically encompasses a range of functionalities that enhance the aircraft's handling and reduce pilot workload. The correct choice emphasizes the role of auto-throttle and auto-pilot systems, which are integral components of AFCS.

The auto-throttle system helps to automatically manage engine power settings to maintain a desired speed or thrust, thereby optimizing fuel efficiency and ensuring smooth operation, especially in varying phases of flight like takeoff and landing. The auto-pilot, on the other hand, takes over the lateral and vertical flight control tasks, allowing the pilot to concentrate on other critical operations or tasks. Together, these two systems are foundational in modern jet transports, assisting pilots in achieving safer and more efficient flights.

Other options suggest functions that may not be as directly associated with the core responsibilities of AFCS. For example, auto-flight and auto-navigate imply a broader scope of functions, but do not specifically address the commonly recognized components like auto-throttle and auto-pilot. Auto-control and auto-recovery confuse the terminology, as these are not standard terms used in the context of AFCS capabilities on commercial jets. Hence, the emphasis on auto-throttle and auto-pilot accurately reflects the standard functionalities of AFCS systems
