What is AFCS?

AFCS can stand for several things, depending on the context. It most commonly refers to an Automatic Flight Control System (AFCS), which is a system that automatically controls the flight of an aircraft. This system often includes autopilot and flight management systems to maintain stability, altitude, heading, and airspeed. However, AFCS can also refer to other things like the Automatic Fare Collection System in transit or Automatic Fire Control System in military applications. Without more context, it is difficult to provide a more specific definition.
