将下列段落翻译成汉语:The automatic flight control systems (AFCS) consist of three independent systems: digital flight control system (DFCS), yaw damper system, and autothrottle system. These systems provide automatic airplane stabilization about the pitch, roll, and yaw axes and control the airplane with selective guidance from radio, heading, flight management computer, and air data computer inputs.
将下列段落翻译成汉语:The DFCS system is a two-axis (pitch and roll) system which operates the elevators and ailerons to automatically maintain altitude, airspeed and/or guide the airplane to designated locations and make automatic landings. Control functions are also translated into flight director commands for display on the pilots’ attitude director indicators.
将下列段落翻译成汉语:An autothrottle system automatically maintains selected airspeeds or Mach during cruise conditions and maintains selected engine thrust settings when making flight director controlled take-offs or autopilot/flight director controlled landing approaches by adjusting engine thrust levers.
将下列段落翻译成汉语:Flight instruments in the cockpit of an aircraft provide pilots with information about the flight situation of that aircraft, such as height, speed and attitude. The flight instruments are of particular use in conditions of poor visibility, such as in cloud, when such information is not available from visual reference outside the aircraft. The main flight instruments are altimeter, attitude indicator, and airspeed indicator.
